Is there a Red Dwarf XIII? https://briefnews.eu/red-dwarf-season-13-will-there-be-another-series-of-red-dwarf-is-there-a-red-dwarf-xiii/ https://briefnews.eu/red-dwarf-season-13-will-there-be-another-series-of-red-dwarf-is-there-a-red-dwarf-xiii/#respond Thu, 09 Nov 2017 22:18:53 +0000 http://briefnews.eu/red-dwarf-season-13-will-there-be-another-series-of-red-dwarf-is-there-a-red-dwarf-xiii/

Lister (played by Craig Charles) and his friends had a hilarious series of adventures in Red Dwarf XII that saw them coming face to face with a non-evil version of Adolf Hitler and Vlad the Impaler in the season premiere to the entire cast transforming into mechanoids like Kryten (Robert Llewelyn).

The UKTV sci-fi hit has also seen foursome run their own presidential elections aboard the Red Dwarf after the machines go on strike and Kryten is running against Rimmer (Chris Barrie).

The show will be coming to an end next week with the final episode entitled Skipper, which will see Rimmer getting his mitts on a Quantum Skipper and ending up in a dimension where he’s actually done pretty well for himself. 

Red Dwarf writer Doug Naylor told Express.co.uk in an exclusive interview: “We’re on a bit of a roll at the moment which is great. The ratings are great, the boys had a really great time making it, want to do more.”

Although the show has not yet officially been recommissioned by the broadcaster, the 61-year-old went on to say of the next season: “Certainly, yes, I think everyone wants to do it including UKTV. Everyone had a blast doing the last 12. 

“We also went to do a tour of some kind at the O2 possibly, so we’ve got a few things in the pipeline and we’re very lucky to be in this situation and it’s great everyone gets on and it’s such a happy team. It’s such a privilege to be involved. Everyone feels like that.”

Doug said that he had some plans for red Dwarf season 13, explaining: “I’ve jotted down lots of ideas – I had so many ideas and we weren’t able to do a lot of them because we were making 12 and not more.

“I’ve got ideas I wasn’t able to do last time and new ideas I’ve got since because post-production lasted the best part of nine to 10 months. So, there was time to jot down ideas and I started writing the next lot anyway. I’m just starting it now.”

Speaking about the end of Red Dwarf season 12, Doug that the last two episodes rounded off the run nicely. 

“The last show was a great one to make. It’s the one where Norman [Lovett] comes back into the show and we have a few guest stars and there’s a real kind of end of term energy about the whole thing. That was 12th show we were making,” Doug said.

He promised some “fantastic sequences” in the episode called Skipper and promised plenty of laughs. 

“I think the fans will absolutely love it,” the star said.

Red Dwarf XI and XII were made back-to-back after the well-loved space comedy got a double commission, however Doug seemed less sure about whether they could make two seasons in one go.

“It would have to fit in with everyone’s schedule. Craig’s very busy and Danny’s very busy as is Chris and Rob. Danny is in Guadeloupe for half a year, so we need to get something that works for him and also we’re quite keen to do a tour.”

“When I say a tour, I mean do a live show at the O2, so we need to get a schedule that works for the O2 and certainly for Red Dwarf XIII. Probably if we did a Red Dwarf XIII and XIV, it would make the O2 live show more difficult.”

He added: “So we’ll probably do Red Dwarf XIII, live show and come back and probably do XIV afterward that.”

The star from Manchester is already busy with ideas for another season of Red Dwarf as well as the live show, however he admitted that he was also working on another sci-fi project.

He teased: “I have written a thing that I thought I’d finished about four months ago and because I’ve got so many things on, I thought what I needed was a couple of days just tweaking it […] but it will still need tweaking.

Doug added: “It’s a science fiction thing, contemporary, two one hours.”

Red Dwarf XII continues Thursdays, 9pm on Dave. Catch up with the series so far on UKTVPlay.

A small body at the edge of our solar system has brought into question the notion that, when it comes to planets, only giants can have rings.

An international team of scientists made the discovery after being treated to a clear view of the dwarf planet Haumea as it crossed between Earth and a distant star in January this year.

Haumea, a pebble-shaped rock named after the Hawaiian goddess of childbirth, is one of the largest space rocks in the Kuiper belt, the disc-shaped region of icy bodies extending from the orbit of Neptune.

As the dwarf planet crossed in front of the star, scientists from the Andalucia Institute of Astrophysics (IAA) in Granada, Spain, coordinated with 10 other labs to examine the data collected by their 12 telescopes.  

“We started to see something weird in the light curve,” the study’s co-author Pablo Santos Sanz told Space.com, recalling how the light dimmed before and after Haumea passed in front of the star, as if something else was obscuring it.

Further research revealed that the dimming was actually evidence of a 43-mile-wide (70 km) ring of debris encircling Haumea at a distance of around 620 miles (1,000 km) from the surface.

Other planets in our solar system which have a ring include Jupiter, Saturn, Uranus and Neptune. The phenomenon is said to be evidence of a collision in the relatively recent history of the planet in question, which is to say the last one billion years.

IAA researcher Dr Jose Ortiz explained that the study, published in the journal Nature, was started after the discovery of a ring around Chariklo, a rock in the Centaurs region of space, in 2014. The Centaurs is an area of space between Neptune and Jupiter.

“We didn’t expect to find a ring around Haumea, but we were not too surprised either,” Dr Ortiz said.

The origins of the ring remain a mystery to scientists, but for some the discovery is yet another sign of the solar system’s unpredictability.

“Our discovery proves that there is a lot more diversity and imagination in our solar system than we had thought,” study co-author Bruno Sicardy of the Paris Observatory told AFP.

Thanks largely to the improvements in our instrumentation, we’ve started to get a picture of what the far reaches of our Solar System look like. Beyond the orbit of the outermost planet, there is a large collection of icy dwarf planets called trans-Neptunian objects, or TNOs. Pluto may have been the founding member of the TNOs, but there are now more than 1,200 known bodies in the list; only 270 of those have even been observed well enough to have their orbits characterized. It’s a safe bet that there will be some surprises among them.

In a paper being released today, researchers are reporting on one such surprise, courtesy of the dwarf planet Haumea: it’s got a ring. The observations that spotted the ring also suggest that Haumea is larger than we thought it was, which means that gravity hasn’t yet pulled it into a stable, rounded shape. Awkwardly, this means that Haumea may not fit the definition of dwarf planet set down by astronomers.

Meet the dwarf

Haumea, named after a Hawaiian goddess, has a closest approach to the Sun of 35 Astronomical Units (AU, the typical distance between the Earth and Sun). For context, Neptune is typically about 30 AU. Due to its highly elliptical orbit, Haumea is over 50 AU at its farthest distance from the Sun. At those distances, not a lot of sunlight reaches it, so most observations of the dwarf planet involve just a few smeary pixels. But we have observed it enough to know that it’s consistently associated with two smaller smears of pixels, its moons Hi’iaka and Namaka. The moons’ orbits told us something about Haumea’s mass.

Red Dwarf will air on Thursday, 9pm on Channel Dave

Many actors claim to suffer  for their craft, whether it’s performing daring stunts or hitting the gym for a big role.

But Robert Llewellyn has perhaps had it harder than most over the years. After all, the 61 year old has now spent three decades enduring painfully long sessions in the make-up chair – as much as five hours at a time – to transform into his robotic alter-ego, Kryten, in sitcom Red Dwarf.

“I think what I really need, at this point, is some quite intensive therapy! You do have to be slightly bonkers to do this job,” laughs Robert, who is unrecognisable without his latex mechanoid outfit.

“It’s got a lot quicker over the years. It used to be four or five hours and now it only takes two. Thankfully, I’m used to it after all this time.”

For fans, it’s a relief to hear that sweltering in a rubber suit has not put the star off returning for a 12th series of the cult sci-fi comedy.

The long-running show, which started on BBC2 back in 1988 and moved to Dave in 2009, follows the adventures of the last human alive, Dave Lister, and his friends, Kryten, Arnold Rimmer and Cat, stranded three million years into deep space.

The new run on Dave sees Robert reunite once again with his co-stars Danny John-Jules (Cat), as well as Craig Charles (Lister) and Chris Barrie (Rimmer), both of whom join him for our interview.

Red Dwarf XII comprises six new episodes, all recorded in front of a live studio audience, and has plenty of treats in store for aficionados.

The good ship Red Dwarf has apparently undergone some major changes – “yeah, we got new lights,” deadpans Craig – while Norman Lovett will be back as Holly, the ship’s computer, after 18 years away.

There’s a rumoured return of Rimmer’s much loved alter-ego, Ace Rimmer, and an exciting array of guest stars, too, including Call The Midwife’s Helen George, The Inbetweeners’ James Buckley and Johnny Vegas (the latter, apparently, as a policeman from a futuristic dystopia).

And interestingly for Robert, his fellow Red Dwarfers will finally get an insight into just how uncomfortable his costume is, when they are all transformed into mechanoids for a special episode. 

“The mask I wore had so much glue on it that I think I was glue sniffing for most of the day,’” says Chris, 57.

“Chris actually got ill wearing it. When I put the mask on, I thought, ‘Why am I crying?’ But I wasn’t – I realised I was just sweating out of my eyelids!” chips in Craig Charles, 53. “We had so much respect for Rob after that.”

The first episode, Cured, sees the Dwarfers come across a space station where the crew has developed a cure for evil, with some entertaining sequences.

 The new series marks the 30th anniversary of the comedy, but far from being bored of the show, Robert admits that he’s always excited to return, partly because of the long breaks they enjoy between filming.

“If we’d been doing it every year, maybe it would be different… time might have dragged. But we’ll do one or two series and then have a year off. We’ve all done a lot of other things in the meantime. It’s great to be back doing it again. I can’t remember life before Red Dwarf. We’re all really close knit. We’re like brothers,” he smiles. 

“We’ve known each for so long, and I’ve had a relationship with these guys unlike any relationship I’ve had with anyone else in my life,” Craig agrees.

“I’ve known them longer than I have my wife and children!”

Of course, the question on everyone’s minds now is whether the boys will return for more Red Dwarf. Could we see them back for a 13th, or even a 14th series in the near future?

“I’d hate for there to be a final episode,” reveals Craig.

“It’s one of those things where we’d just want to quietly sail off into the distance and not make too much of a fuss about it. The problem with writing final episodes is that they’re always disappointing.”

“There’s definitely a demand for more, though,” adds Robert.

“I’m sure we will be back. But we’d better hurry up; we don’t have long left at our age. 

“And particularly for me… You don’t want to be covered in rubber in old age. It really isn’t good for you!”

Strange signals emanating from a dwarf star are not evidence of extraterrestrial life. That’s according to astronomers who detected the unidentified radio signals, setting off public speculation that aliens were trying to making contact with Earth.

Scientists from the Arecibo Observatory in Puerto Rico revealed last week that they were baffled by signals detected on May 12 emanating from the star Ross 128.

The wide-band radio signal was considered unusual because not only did it repeat with time, it also slid down the radio dial, going from a higher note to a lower one.

While the team were quick to point out that it was highly unlikely the signals were from aliens, that didn’t stop curious conjecture around their discovery.

“Many people were more interested in the signals as potential proof of transmissions from an extraterrestrial intelligent civilization,” Professor Abel Mendez from the Planetary Habitability Laboratory wrote in a press statement.

“Statistically, this is always the last consideration, not because such civilizations are impossible, we humans are an example, but because other possibilities had frequently arisen and no extraterrestrial civilizations have been detected yet.”

Mendez is now confident that he and his team have solved the mystery of the signal, officially called “Weird!”

After careful analysis of the observations, with assistance from the SETI Institute, the source of the signal was determined to be interference from a distant satellite.

“The best explanation is that the signals are transmissions from one or more geostationary satellites. This explains why the signals were within the satellite’s frequencies and only appeared and persisted for Ross 128; this star is close to the celestial equator where many geostationary satellites are located,” Mendez said.

The team fell short of explaining the shape of the signal and will continue to investigate this.

Before confirming the results publicly, Mendez took advantage of the huge media attention to gauge what the public believed was the most likely source of the signal.

Nearly 800 people, including more than 60 astronomers, participated in the informal survey.

The majority of those surveyed believed the signals were a result of some astronomical phenomenon. Interestingly, the possibility of radio interference or instrumental failures were considered least likely.

About one quarter of respondents said the most likely explanation of the signal was that of a communication with an Extraterrestrial Intelligence (ETI). A similar number, however, said this was likely only “in our craziest dreams.”

Astronomers on the hunt for habitable worlds beyond our solar system say they have picked up “strange signals” emanating from a nearby star, 11 light years away.

Scientists from the Arecibo Observatory in Peru are studying red dwarf stars in the hope that they might find planets orbiting them. On May 12, they observed mysterious radio signals emanating from a star called Ross 128.

Could these radio signals be signs of extraterrestrial life? Prof. Abel Méndez, planetary astrobiologist and director of the Planetary Habitability Laboratory at the University of Peru, doesn’t think it’s very likely.

“In case you are wondering, the recurrent aliens hypothesis is at the bottom of many other better explanations,” Méndez wrote in a recent blog post.

However, the source of the strange signals still eludes the team. One theory about the source is solar flares – powerful outbursts of energy shooting out from the star’s surface travelling at light speed.   

A second theory is that the signals are actually coming from another object within the field of view of Ross 128. However, as Mendez says, “there are no[t] many nearby objects in the field of view of Ross 128,” further deepening the mystery.

The signals could also be coming from something far closer – a high orbit satellite which passed through the telescope’s field of view, but which moved too quickly to be detected. However, this seems an unlikely source for the mysterious signals.

“We have never seen satellites emit bursts like that, which were common in our other star observations,” Mendez said of this theory.

Whatever the signals are, they are “not local radio frequency interferences” and are “unique to Ross 128,” as similar observations of other stars did not show anything quite like it.

Dwarf stars have already been shown to have planets orbiting the habitable, or ‘goldilocks,’ zone, as is the case with the recently discovered TRAPPIST-1.

Mendez and his team will once again observe Ross 128 on Sunday, July 16. Until then, we’ll have to wait patiently just like Prof. Mendez.

He’ll be having a drink to celebrate if and when results come in. “I have a Piña Colada ready to celebrate if the signals result to be astronomical in nature,” he said.

A new study has revealed that the third-largest dwarf planet in our solar system has its own moon.

Researchers used three different space observatories to confirm that dwarf planet 2007 OR10, which is nicknamed “Snow White,” is orbited by a moon.

Snow White is a 1,530 kilometer-wide (950 mile) dwarf planet, while the new moon has been measured at between 240 to 400 kilometers (150-250 miles) in diameter. They are located in the frigid Kuiper Belt, on the outskirts of our solar system, beyond Neptune.

The moon was spotted in archival images of Snow White taken by NASA’s Hubble telescope. Observations of the dwarf planet by the agency’s Kepler Telescope first alerted astronomers to the possibility of a moon circling it.

Dwarf planets resemble small planets but they lack certain technical criteria that are required to be classed as such.

The discovery means that astronomers have now found moons orbiting most of the known dwarf planets in the Kuiper Belt. This latest discovery provides researchers with valuable clues into how moons formed in the young solar system.

“The discovery of satellites around all of the known large dwarf planets – except for Sedna – means that at the time these bodies formed billions of years ago, collisions must have been more frequent, and that’s a constraint on the formation models,” said Csaba Kiss of the Konkoly Observatory in Budapest, Hungary. “If there were frequent collisions, then it was quite easy to form these satellites,” Kiss added.

Scientists theorize that the objects most likely slammed into each other more often because the region was crowded. The speed of the colliding objects also played a key role as it could not have been too fast or too slow.

If the impact velocity was too fast, the collisions would have created lots of debris that could have escaped from the system; too slow and only an impact crater would have been produced.

When we think of dwarf planets, the first thing that comes to mind is obviously the injustice of Pluto getting demoted to one. But the truth is, these little guys—and there are six currently recognized within our solar system—deserve just as much love as their mightier planetary cousins. Good news for them: a new study suggests that the dwarf planet club could get another member, in the form of a very small, distant object located roughly 92 astronomical units (AU) from the Sun.

Planetary body 2014 UZ224, also known as DeeDee (short for “distant dwarf”), has been getting a lot of attention from a team of scientists who’ve observed it using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. Though DeeDee was first discovered using the Blanco telescope in 2014, this new study has been able to record its size for the first time. By picking up DeeDee’s heat signature, the ALMA data suggests the object is about 635 kilometers across, about two-thirds the diameter of dwarf planet Ceres.

If DeeDee has enough mass to be spherical, it would meet the criteria for the International Astronomical Union (IAU) to recognize it as a dwarf planet. In order to be recognized as such, an object must orbit the Sun but cannot be a satellite (like a moon), must have enough mass to be spherical, and has not cleared its planetary neighborhood of debris. The team’s observations were published on April 12th in The Astrophysical Journal Letters.

“This object is currently the second-most distant known trans-Neptunian object with reported orbital elements, surpassed in distance only by the dwarf planet Eris,” the researchers wrote. Trans-Neptunian objects (TNOs) are minor objects that orbit the Sun at a distance greater than Neptune does at 30 AU. We suspect there are thousands of TNOs in our solar system, and while they may seem distant and unimportant, they’re essentially scraps from the formation of the solar system—so very old and very cold.

Indeed, DeeDee might not be as cute as its name suggests. In addition to taking 1,100 years to complete its orbit around the sun, the object is blisteringly chilly, which makes sense seeing as it’s located in the Kuiper Belt where our sun is no more than a bright pinprick in the sky. The region is chock full of ancient ice balls.

“We calculated that this object would be incredibly cold, only about 30 degrees Kelvin, just a little above absolute zero,” lead author David Gerdes, a scientist with the University of Michigan, said in a statement.

Despite its unbearable coldness, it’d be nice for Pluto to have another dwarf planet to befriend. We’ll be rooting for you, DeeDee.

NASA has released its highest-resolution color image of Pluto, showing the dwarf planet dramatically backlit by the sun.

The receding crescent was snapped by the New Horizon Spacecraft as it traveled some 120,000 miles (200,000 km) from Pluto.

Somewhat confusingly, the space agency dubbed the photo as a “Farewell to Pluto” because the shot was captured during New Horizons’ departure from the planet, and not because Pluto or the spacecraft are going anywhere.

The image, described by NASA as being “shown in approximate true colour”, is constructed from six black-and-white images taken by the Long Range Reconnaissance Imager (LORRI) and one color image from the lower-res Ralph/Multispectral Visible Imaging Camera (MVIC).

All photos were taken about three and a half hours after New Horizons made its closest approach to Pluto on July 14, 2015.

The image showcases Pluto’s spectacular blue haze atmosphere — a photochemical smog composed of a mixture of methane and other molecules as it was illuminated from behind by the sun.

The layers of haze extend to altitudes of over 200 kilometers (120 miles) from Pluto’s surface.

  • TRAPPIST-1, a red dwarf star 39-light-years away from us, has seven Earth-size planets orbiting it.
  • It’s likely that all of these worlds are rocky and may possibly harbor liquid water.
  • Red dwarf stars are the most abundant type of star in the Milky Way galaxy.
  • In the future, telescopes might be able to detect light that passes through the planets’ atmospheres — and possibly signal the presence or absence of alien life.

Less than a year ago, astronomers announced an astounding discovery: They’d found three Earth-size planets orbiting a small, dim red star.

But as it turns out, their first observations missed a whole bunch of worlds.

The astronomers now think seven rocky planets similar to our own may circle the star, called TRAPPIST-1 — an “ultra-cool” red dwarf located about 39 light-years away in the constellation Aquarius. Thirty researchers from around the world announced the new discovery Tuesday in the journal Nature.

The team’s surprise didn’t end with an increased world count, though.

Each planet orbits TRAPPIST-1 in the star’s Goldilocks-like habitable zone — a region where there’s enough starlight to permit the existence of liquid water. Four of the seven worlds may even be candidates for hosting alien life, team members said Tuesday during a press teleconference call.

“This is really the first time we have seven planets that we can say are in terrestrial zone, and it’s really, really surprising,” said Michaël Gillon, a study co-author and astronomer at the Université de Liège in Belgium.

The discovery of the new worlds, each within 10-20% of the size of Earth, may have profound implications for the search for extraterrestrial life beyond the solar system.

An alien, yet possibly common, solar system

The dwarf star and its system of seven known planets — called TRAPPIST-1b, 1c, 1d, 1e, 1f, 1g, and 1h — is relatively small compared to our own.

In fact, one “year” on the innermost planet, 1b, takes about a day and a half on Earth. The outermost planet, 1h (which scientists have caught only a fleeting glimpse of), takes about 20 Earth-days to orbit the star.

“If we put the TRAPPIST-1 star [in] the place of the sun, we’d have all seven planets inside the orbit of Mercury,” Emmanuël Jehin, another co-author at the Université de Liège, said on the call.

But that isn’t a deal-breaker for the possibility of life.

TRAPPIST-1’s surface temperature is about half that of the sun’s, making it “ultra-cool” as stars go. However, if a planet orbits closely enough, it can receive the same amount of solar energy as the Earth receives from the sun at 93 million miles away. All of TRAPPIST-1’s worlds appear to be “temperate” and not close enough to get roasted.

The team said it’s “very hard to know” if they just got lucky with their unprecedented discovery of seven Earth-size planets around a single star, or if such an abundance of worlds is common, said Amaury Triaud, fellow co-author and astronomer at the Institute of Astronomy in Cambridge, UK.

Either way, the bounty of worlds may vastly improve the chances that humans aren’t alone in the Milky Way galaxy, let alone the universe at large.

red dwarf star exoplanetHarvard-Smithsonian Center for AstrophysicsThat’s because red dwarf stars comprise “30 to 50%” of our galaxy’s 100 to 400 billion stars, Triaud said, which makes them the most abundant and long-lived type of star around. (Sun-like solar systems represent only about 10% of those discovered thus far, the researchers said.)

“I think we’ve made a crucial step toward finding life out there,” Triaud told Business Insider during the call.

“I don’t think we’ve had the right planets to look at,” he said. “If life managed to thrive and release gases similar to those here on Earth, then we will know. We have the right targets.”

Another target could also be Proxima Centauri, a red dwarf just 4.24 light-years away — many times closer than TRAPPIST-1. In 2016, astronomers learned this star system may harbor an Earth-like planet called Proxima b.

NASA’s upcoming James Webb Space Telescope (JWST) might be able to study the probable world’s alien atmosphere for signs of life. A Russian billionaire is also backing an ambitious mission to laser-propel a fleet of tiny spacecraft toward Proxima Centauri and its close neighbor Alpha Centauri to directly study and photograph any worlds around the stars.

Why there could be life around TRAPPIST-1

trappist 1 seven earth size planets discovery nature 7NASA/JPL-Caltech

Since astronomers verified the discovery of the first exoplanet 25 years ago, scientists have gradually come around to the idea that life is probably common in the universe. (Whether or not it’s intelligent, angry, friendly, or indifferent, however, is a different matter.)

The transit method, where a planet passes in front of a star and dims its light ever-so-slightly, showed humanity that perhaps trillions of planets may exist in our galaxy alone.

Gillon and his colleagues used the same method to discover the seven new worlds. They found the first three in previous years using a ground-based telescope named TRAPPIST. They detected the four additional worlds featured in the new study by staring down TRAPPIST-1 for 20 consecutive days with NASA’s Spitzer Space Telescope.

And, as previously mentioned, more-abundant stars that are much cooler than the sun can warm up rocky planets enough to melt water; that is, if they have enough insulating gases in their atmospheres.

“It’s possible their atmospheres are very similar to the Earth, or Venus, or something completely different,” Gillon said.

The study suggests that the diameters and masses of each planet, estimated based on the amount of starlight dimming they cause, match up with that of rocky worlds, and possibly those that harbor water as ice or liquid oceans.

That’s not to say life is guaranteed around TRAPPIST-1.

Dangerous space weather, including solar flares and coronal mass ejections, could endanger any aliens by blasting them with dangerous high-energy particles. And unfortunately, red dwarf stars — more than most other types of stars — are known for such temper tantrums.

The planets also seem to orbit in “resonance,” which could mean that they may be tidally locked and always facing the star with the same side, much like Jupiter’s largest moons.

But neither of these necessarily mean doom for any life that may exist there, the researchers said.

For one, Gillon said, TRAPPIST-1 “is a very quiet star” as far as giant balls of fusing plasma go.

Gillon also says orbital resonances and tidal locking may actually be an advantage.

“This could lead to a huge tidal heating in the cores of the planets,” he said, by kneading them with gravitational strain.

Such warmth could melt ice into liquid, belch insulating gases into the planet’s atmosphere through volcanism, and generally stir up the ingredients for life.

What’s next for TRAPPIST-1

Gillon said the team’s discovery of TRAPPIST-1’s seven planets “is just the beginning.”

Direct photographs of the planets may not be possible, the researchers said. But in the near future, the scientists hope to use telescopes like JWST — scheduled to launch in 2018 — to peek at starlight that passes through the atmospheres of the planets.

The technique could help them measure how much oxygen, ozone, and other gases the worlds might contain.

“For instance, oxygen can be produced by photolysis of water on a water-rich planet,” Gillon said. “It’s really the molecules and their relative abundances that enable us to give the plausible or restricted extent of life. We’ll see.”

And even if TRAPPIST-1 seems to be a dead or sterile planetary system now, that still doesn’t mean it’s an unlikely place to seek out aliens in the future.

“But one thing is certain: in a few billion years, when the Sun has run out of fuel and the Solar System has ceased to exist, TRAPPIST-1 will still be only an infant star. It burns hydrogen so slowly that it will live for another 10 trillion years” Snellen wrote, adding that’s “more than 700 times longer than the Universe has existed so far, which is arguably enough time for life to evolve.”
