Asteroid impacts may have helped make Mars a more life-friendly place — and not just by delivering water and the carbon-based building blocks of life as we know it to the Red Planet.

Is Earth an exhibit in an alien zoo?

The Russian-built landing platform for the ExoMars rover now has a name: 'Kazachok.'

Scientists hunting for signs of alien life shouldn't be so quick to dismiss carbon monoxide, a new study suggests.

NASA's Europa Clipper mission could receive $600 million for the fiscal year that begins in October, according to budget request documents released today (March 11) by the Trump administration.

NASA's recently deceased Kepler space telescope launched on March 6, 2009, ushering in a new era of planetary science.

Cosmic impacts on young Mars may have triggered deluges, potentially explaining why the Red Planet was once covered in water, a new study finds.

Scientists found valleys, channels, ridges and curved deltas in the depths of Martian craters, and those features provide the first evidence of a vast groundwater system in the planet's past.

Drilling for signs of life on Mars, as two rover missions plan to do soon, is a pretty sound strategy, a new study suggests.

If you want to share a meal with an alien, you may have to begin by broadening your definition of a meal. A lot.

Hydrothermal vents, where the planet's heat seeps out into the deep ocean through cracks in Earth's crust, are candidates for where life may have began — and scientists have built them in the lab.

We may not have to wait much longer to get our first glimpse of E.T., NASA chief Jim Bridenstine said.

Some parts of the dwarf planet Ceres harbored pockets of near-surface water for millions of years in the recent past, a new study suggests.

NASA is launching a new research partnership to tackle the search for life beyond Earth, including life that may look very different from the kinds we're familiar with.

The atmosphere surrounding the largest TRAPPIST-1 planet makes a strong case for it being a rocky world.

For more than two decades, scientists have wondered whether extraterrestrial life may be flourishing deep below the icy coatings boasted by moons in our outer solar system.

One of Earth's nearest exoplanet neighbors, the planet orbiting Barnard's Star, may still have a chance at hosting life, despite its frigid temperatures.

With research on extraterrestrial life continuing across the world, a noted researcher from the SETI Institute launched a new tool to help researchers keep track of results.
