[ad_1] An artistic rendering of a Dyson sphere around a star. | Photo credit: iStock images Highlights The Dyson sphere, as it is called, is a massive superstructure that surrounds a star, capable of gathering the energy it releases The recent study probed that if a similar structure was built around a black hole instead … Read more
[ad_1] Looking across the Universe is difficult. Fortunately, the Universe sometimes provides a little help, using gravity to give light a quick kick in the photons. I’m talking about a gravitational lens: In short, the gravitational lens occurs when the gravity of a massive object – a star, a black hole, a galaxy – curves … Read more
[ad_1] An artist’s concept of a planet eaten by its mother star. NASA / ESA / G. Bacon By Adam MannAug 30, 2021, 13:15 Like the Greek god Chronos, many stars devour their children. Up to a third of them have swallowed one or more of their own planets, a new study suggests. The findings … Read more
[ad_1] -. Credit: Tokyo Tech The current global climate emergency and the rapid decline in our energy resources are pushing people to seek cleaner alternatives like hydrogen. When burned in the presence of oxygen, hydrogen gas generates huge amounts of energy but none of the harmful greenhouse gases, unlike fossil fuels. Unfortunately, most of the … Read more

[ad_1] Tardigrades are undoubtedly strange. Dehydrate them in glass, then shoot them with a gun, and once you rehydrate them you can still have a living creature. Their exteriors aren’t the only thing that’s difficult either, with scientists finding out last year that they also have special DNA armor proteins. But if we take a … Read more
[ad_1] Bernese theoretical astrophysicist Kevin Heng has achieved a rare feat: on paper, he has found new solutions to an old mathematical problem needed to calculate light reflections from planets and moons. Now the data can be interpreted in a simple way to understand planetary atmospheres, for example. The new formulas will probably be incorporated … Read more
