‘Nobody looked at this before’: Parker solar probe shares first up-close look of the sun (PHOTO)

A clear image of plasma flowing from the sun taken by the Parker Solar Probe during its rendezvous with the center of our Solar System has amazed NASA scientists who now expect more treasures from the robotic spacecraft mission. While the solar approach of the probe took place on November 8, NASA only recently received […]

Floating solar is more than panels on a platform—it’s hydroelectric’s symbiont

Mysterious interstellar asteroid could be a solar sail from wrecked alien probe, astronomers say

Interstellar mystery rock Oumuamua might have been part of an alien reconnaissance mission, according to two Harvard Smithsonian astronomers who saw in the strange object signs it could be a light-driven probe. As the strange rock moved out of our solar system last September, it sped up instead of slowing down as would be expected. […]

Five solar roof shingles that aren’t from Tesla

Colliding stars or alien solar sails? Detection rate of mysterious space signals doubles

The detection of incredibly powerful signals from deep in space has increased dramatically and the mysterious radio waves are now closer and brighter than ever before. The phenomena, known as ‘fast radio bursts’, have puzzled scientists since their discovery more than a decade ago and now Australian researchers have announced, in a study published in […]

Brice/Wattway) Four years ago a viral campaign wooed the world with a promise of fighting climate change and jump-starting the economy by replacing tarmac on the world’s roads with solar panels. The bold idea has undergone some road testing since then. The first results from preliminary […]

Trump’s solar tariff isn’t hurting the industry as much as everyone expected

(credit: Robert Nickelsberg/Getty Images) On Thursday, the Solar Energy Industries Association (SEIA) published a quarterly report that offered surprising results. Despite a 30-percent tariff on solar cells and modules imported to the US, solar installations only fell by about nine percent, year over year. At the […]

Carpeting Sahara with wind and solar farms could make it rain

Enlarge / “Whaaaaaaaat?” (credit: Lisa de Vreede) If you’ve spent any time thinking about the world’s dirty energy problem, you’ve probably pondered some impractical “What if?” scenarios. Solar panels in space beaming energy down, or covering Nevada in solar panels—that kind of thing. Well, a new study led by Yan Li, Eugenia Kalnay, and Safa […]
