A few years ago, researchers studying stromatolites in Greenland dated them to 3.7 billion years old, making them the oldest evidence of life on Earth. However, a new study has now taken another look at the rocks and found that they probably weren’t biological in origin.

While NASA has plans to possibly send a lander to Europa in the coming years, a new discovery might make touchdown tricky – there’s a chance that large swathes of Europa’s surface are covered in ice spikes almost 50 ft (15 m) high.

Scientists may have discovered large amounts of water hidden deep beneath the surface of Jupiter’s famous Great Red Spot. The discovery, which was made using ground-based telescopes, opens up the possibility that extremophile lifeforms could exist in the atmosphere of the enigmatic gas giant.

The further back in time you go, the patchier our understanding of life on Earth gets. Now, British scientists have used a different method known as a molecular clock to plot out a rough timeline of all life on Earth, tracing the first organisms back to about 4.5 billion years ago.

Two worms frozen in the Siberian permafrost for around 40,000 years have now been thawed and revived, making them the oldest living creatures on the planet and the first multicellular organisms to have survived such long-term cryobiosis.

Scientists have long sought an explanation as to why stable conditions on Earth have persisted long enough for life to evolve over millions of years. Now a team has hit upon two mechanisms, "sequential selection" and "selection by survival alone," as a possible solution to this "Gaia puzzle."

When looking for exoplanets that could potentially support life, astronomers start with those orbiting within the “habitable zone." A new study has found that two of the most promising planets are now even more promising, with axial tilts that likely give them regular seasons and a stable climate.

According to the results of a new study, soon after the creation of the solar system, Mars may have formed a primordial crust capable of hosting life. The research is based on an analysis of the rare and super-valuable Black Beauty meteorite, which was discovered in the Sahara Desert back in 2011.

Saturn’s moon Enceladus is one of the most promising places in the Solar System to look for extraterrestrial life. Now Cassini mission data has shown the presence of complex organic molecules, spraying up from the moon’s subsurface ocean through cracks in the icy shell.

Scientists have found the earliest animal footprints ever discovered. The tracks and burrows, dating back half a billion years to the Ediacaran Period, were made by some of the earliest bilaterian animals, and reveal that more complex lifeforms arose earlier than previously thought.
