Unusual chemical compounds found on rocks on Mars could be a sign that life once existed on the red planet, though researchers have cautioned the evidence is far from conclusive.

Sapphire Canyon, a rock sample collected by NASA’s Mars rover, may hold the clearest evidence yet of ancient life on Mars. Scientists revealed that unusual dark markings on the rock, along with signs of water and organic molecules,

On the Red Planet, aurorae glow green because the charged particles collide with oxygen atoms high above Mars. They may be bright enough that astronauts on Mars could spot them with their naked eye. Here on Earth, it’s usually helpful to have a telescope or even a phone camera filter to really see the aurora.

The Perseverance rover’s new findings set the stage for bringing Martian samples back to Earth to test whether microbes once inhabited the Red Planet

Recently, scientists made a stunning discovery that beneath Mars' ice layers, there exists a 'radiation habitable zone,' where life could potentially be hidden within 1.5 meters of ice dust! This really challenges our previous understanding of Mars.

How close are we to answering the biggest question of all—are we alone? With new discoveries on Mars and Jupiter, scientists say we may be nearer than ever to proving alien life exists. This video explores the latest breakthroughs and what they mean for humanity.

Mars has always held a special fascination for humanity. Since the 19th century, when telescopic observations fired the imagination with supposed canals and dried seas, the question refused to go away: did the Red Planet once harbor large bodies of liquid water?
