Life on mars

The organic carbon was found in mud samples dating back 3.5 billion years, just after Mars lost its atmosphere.

A transgenic lettuce may address bone loss not only for space travelers but also patients on Earth.

A photo appearing to show an alien basking on the surface of Mars has caught attention online recently—but is it possible that Mars could host such a life form?

Space researcher Sara Motaghian described the results as "really cool" to Newsweek, and said they could help in the search for life on the surface of Mars.

This recent finding signified that the Red Planet could contain deeper water stores covered by dust.

The Ingenuity copter is the first vehicle to perform a powered, controlled flight over the surface of an alien world.

Following years of analysis, the results of experiments conducted by the rover's SAM instrument, which searched for the building blocks of life on Mars, are in.

Researchers who suggest Mars' size could explain why it lost its water are the latest team to consider how Earth's neighbor became the Red Planet.

NASA Administrator Bill Nelson described the rover sampling the first core sample ever drilled from an alien world as a "momentous achievement."

Scientists hope the technology could help future Mars-goers produce breathable air and rocket fuel for return trips.

The unmanned spacecraft made it to Mars on Thursday after a long, seven-month trip.

The NASA craft lands this afternoon and will immediately set to searching for evidence of water.

"Organic molecules are those that contain chains and rings of carbon atoms linked together—like those used by life," said researcher Atsuko Kobayashi.

The rover will search for signs of past microbial life on Mars, while also investigating the planet's climate and geology.

The 'abiotic' methane may hold clues about its presence elsewhere in the solar system, researchers say.

Warmer conditions on Ancient Mars increase the possibility that life developed there, according to researchers.

Harvard-led team say a thin layer of silica aerogel could insulate the planet's surface.

The discovery could have significant implications in the search for signs of past life on the Red Planet.

Methane is one of the potential markers to indicate that life once existed on the red planet.

A study shows Mars's rivers persisted up until one billion years ago—and possibly for even longer than that.

A new study suggests that the Red Planet could have supported subsurface microbes.

Is the briny sludge teeming with tiny organisms?

Scientists found that Mars's crust formed much earlier than previously thought.

The rover has discovered ancient organic material that may be biological in origin, although this has not yet been proven.

These rocks formed at the bottom of ancient lake beds between three and four billion years ago, when the Martian surface was abundant in water and its climate was warmer.

The ExoMars Rover will drill more than six feet underground to search for organic material.

The new find might also reveal what life on Mars could look like.

Laguna Caliente in Costa Rica is one of the harshest environments on Earth for life.

The dents could have been left by life long ago, says one scientist.

The search for alien life is closer to home than one may think.
