Life

The latest ingredients of life to be discovered off-world are certain bio-essential sugars, which have now been found in meteorites. This could lend weight to the idea that meteorite impacts are responsible for the origin of life on Earth.

A new Japanese study simulated interstellar clouds of dust and gas, and managed to produce some of the building blocks of DNA.

Scientists have found some of the earliest direct evidence of life, in the form of organic remains in 3.5-billion-year-old stromatolites in Australia.

A new study argues that the death of a huge asteroid caused an ice age that dramatically altered the evolution of life on Earth.

Just how common are potentially habitable Earth-like planets? Researchers on a new study claim to have come up with the most accurate estimate yet – and they’re more common than you might think.

While we have some idea about what kinds of signs of life to look for on other planets, many of these can also be created under natural processes. Now NASA is about to launch a new mission that can help root out these false positives by studying the interactions between stars and their planets.

Exactly how life sprung out of non-living matter is one of biology’s biggest mysteries. In new research, scientists cooked up a “primordial soup” and found that some of the crucial building blocks of life spontaneously stacked themselves in a surprisingly efficient way.

A new study has used simulations to show that even Earth-like planets completely encased in ice could still have areas warm enough for life, muddying up the already-murky definition of habitable worlds.

NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered three worlds orbiting a star located a mere 73 light-years from Earth. The exoplanets are a tempting target for scientists hoping to understand how planets form, and may even be a future hunting ground for E.T.

The biggest missing link lies between non-living matter and the earliest living cells. A new study has found a mechanism that may have helped droplets transition into early cells, taking place in ponds, puddles and waterways that dried out and refilled repeatedly over time.

Statistically it’s pretty much a given that alien life is out there, whether that’s Martian microbes or intelligent life beaming comms through the cosmos. Now, a new telescope array has joined Breakthrough Listen, scanning for flashes of laser light that alien civilizations might be giving off.

Modern Mars is a desolate husk of a planet, as far as life is concerned. But it’s not completely uninhabitable, since microbes could be hiding in the cracks of rocks and dirt. And now a new study has found a possible food source for these organisms – space dust.
