A remarkably hardy bacterium can survive pressures similar to those generated when asteroid impacts blast debris off Mars, a ...

Tiny life forms tucked into debris from an asteroid hit could catapult to other planets—including Earth—and survive, a new ...

New research using NASA’s James Webb Space Telescope examines the maximum sizes of gas giant exoplanets, measuring chemical compositions and formation processes in the HR 8799 system.

Researchers analyzed 28 Ryugu asteroid samples and found preserved magnetic signals that record early solar system magnetic fields and water-driven alteration on its parent body.

Infant planets are ravenous little blighters that quickly devour what remains of the star-circling gas and dust clouds in which they form. The gas in these protoplanetary disks disappears rapidly, ...

Ohio, US: A recent study has revealed that super-Earth exoplanets, worlds that are larger than Earth but smaller than Uranus or Neptune, are far more common in the universe than previously believed.

Water is essential for life on Earth. So, the liquid must be a requirement for life in other worlds. For decades, scientists' definition of habitability on other planets has rested on this assumption.

A new analytical transmission model incorporating pressure-dependent opacity improves interpretation of exoplanet atmospheres and supports data analysis from JWST and the upcoming ARIEL mission.

When you see art of our solar system as the planet orbit the sun, you may notice that Earth's orbit has a tilt. It is not a perfect circle. What's more, Earth is not the only planet that displays such ...
