Astronomers want to collect as much data as possible using as many systems as possible. Sometimes that requires coordination ...

A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST’s powerful vision, astronomers detected sulfur in their atmospheres — a chemical clue that they formed ...

A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, ...

SIGNS of an alien planet that’s about the same size as Earth have been picked by up a Nasa telescope. Scientists say it might ...

The researchers discovered the candidate world while examining data gathered by the NASA Kepler space telescope in 2017. It ...

They show up as a mathematical solution in general relativity, basically as a time-reversed version of a black hole. Some ...

Of the 6,000 exoplanets known, a very thin slice of them are in the geometry required to perform a deceitfully simple ...

Gas giants are enormous planets made primarily of hydrogen and helium. They may contain dense central cores, but unlike Earth, they do not have solid ...

The Earth-size planet HD 137010 b has a ‘50% chance of residing in the habitable zone’ of its sun-like star, scientists say ...

Scientists have discovered something that they previously thought wasn’t possible – an ‘inside out’ star system. When you ...

Jupiter is the largest planet in our Solar System and the fifth planet from the Sun. It is a massive gas giant made mostly of hydrogen and helium, the same elements that form stars.

Precious metals may be escaping from the planet’s core. This hotly debated subject could help us understand Earth’s evolution and determine whether life exists elsewhere in the Universe ...
