A new theory suggests that NASA's Curiosity rover could be "burping" the surface of the Red Planet, releasing methane trapped beneath a salty crust.

When it arrives at Jupiter and the planet's moons in 2031, the JUICE spacecraft will use ice-penetrating radar to see beneath determine habitability.

The great planetary instability coincides with the collision that formed Earth's moon — could the two events be linked?

Earth's ancient magnetic field appears to have had a strength similar to what we see today, and it may have protected ancient life from harmful cosmic radiation.

Japan's SLIM lunar lander has now survived three week-long nights on the moon, braving temperatures as low as minus 274 degrees Fahrenheit, despite not being designed to last one!

Earth's magnetic shield weakened around 41,000 years ago, resulting in increased bombardment of our atmosphere by energetic charged particles called cosmic rays.

Scientists turned into cosmic crime scene investigators to reconstruct the impact that sent Earth's "quasi-moon" Kamo'oalewa rocketing from the lunar surface millions of years ago.

The quadruple eruption was captured by NASA's Solar Dynamics Observatory.

How Pluto's Sputnik Planitia formed remains unknown, but researchers have imagined a body about the size of Switzerland crashing into Pluto at a shallow angle.
