In the late 1970s, NASA declared 'no life on Mars' when the Viking landers failed to find organic molecules (but they did). So was that conclusion a mistake?

Dying old stars destroy their planets, new research shows

Astronomers have found new evidence that dying stars destroy their planets - with the closest planets at greatest risk - as the stars swell up into red giants.

Could black hole shadows reveal new theories of gravity?

A new international study proposes how astronomers could use future improved images of black hole shadows to test alternative theories of gravity.

Hidden ocean on Enceladus might be stable enough for life

The subsurface ocean on Enceladus is stable enough for life, a new study of data from the Cassini mission suggests. Heat flow at both poles provides the clues.

1st 3D temperature map of exoplanet shows dynamic atmosphere

Astronomers have created the 1st 3D temperature map of a distant exoplanet. The planet, WASP-18b, is a scorching ultra-hot Jupiter 400 light-years away.

Yeast on Mars could survive, unique new research shows

A new study from scientists in India shows that yeast could survive on Mars, tolerating both shockwaves from impacts and toxic perchlorate salts.

3 Earth-sized planets around double star surprise scientists

Astronomers discovered 3 Earth-sized planets in the binary star system TOI-2267. It's the first time where the planets are orbiting each individual star.

Super-Earth 18 light-years away sparks hope for life in space

Astronomers have found a new super-Earth 18 light-years away. Exoplanet GJ 251 c is both nearby and in the habitable zone of its star.

Transient flashes in ’50s sky plates still puzzle scientists

Scientists see mysterious transient flashes of light in 1950s sky images from the Palomar Observatory. It was before the 1st satellites. What were they?
