New study suggests tighter restrictions on exoplanet habitability

Accounting for the buildup of toxic gases predicted to occur in the atmospheres of most planets narrows the habitable zone for complex life by half and, in some cases, rules it out altogether, the study concludes.

Harsh radiation no barrier to life on nearby exoplanets

Hopes for finding life on four rocky exoplanets relatively close to Earth have been boosted by new modelling that shows biological systems could survive the intense and prolonged bursts of X-ray and UV radiation.

Complex Life Might Require a Very Narrow Habitable Zone

A research into how life evolved on Earth has shown that water alone does not guarantee life – nor does the presence of oxygen gas. And that two other major biosignatures, carbon dioxide and carbon monoxide could be needed.

Newly Found Planet Could Host Primitive Life, Study Suggest

Barnard b or GJ 699 b – might have microbes or other simple life in its environment as long as there is a lot of thermal activity within the planet itself. This would theoretically provide enough energy for life to survive.

The Closest Exoplanet Planet Could be Habitable With a Dayside Ocean

A new NASA-led study shows that Proxima b could support the existence of an ocean on its dayside, which means it could still be habitable.

This Rocky Exoplanet Is the Most Likely to Support Life

Of the thousands of known exoplanets, Kepler-452b has the most ideal combination of UV light exposure and conditions for liquid water.

Exoplanets may contain vast amounts of water

Scientists have shown that water is likely to be a major component of those exoplanets which are between two to four times the size of Earth. It will have implications for the search of life in our Galaxy.

121 giant planets that may have habitable moons

US Researchers have identified more than 100 giant planets that potentially host moons capable of supporting life. Their work will guide the design of future telescopes that can detect these potential moons.

NASA Planet Hunter on Its Way to Orbit

NASA’s Transiting Exoplanet Survey Satellite (TESS) has launched on the first-of-its-kind mission to find worlds beyond our solar system, including some that could support life.

Good News For The Search For Life, - The Trappist System Might Be Rich In Water

Scientists have been hard at work trying to determine the densities of the TRAPPIST-1 planets, and it looks like water is abundant in the TRAPPIST system.

TRAPPIST-1 Star System Contains Two Potentially Habitable Planets

It’s been less than a year since astronomers detected TRAPPIST-1, a remarkable star system located 39 light years from Earth. New research suggests life could take root on at least two of these planet.

Periodic Table of Exoplanets Classifies Over 3,700 Known Worlds

Astronomer from Puerto Rico has put together a Periodic Table of Exoplanets, where each of the 3,700 confirmed exoplanets is slotted into its own discrete category—including planets that could harbor life.

Exoplanet 55 Cancri e likely to have atmosphere

Twice as big as Earth, the super-Earth 55 Cancri e was thought to have lava flows on its surface. Now, a new analysis finds this planet likely has an atmosphere whose ingredients could be similar to those of Earth.

Three Possible Super Earths Discovered Around Nearby Sun-Like Star

A recent study involving data collected by the K2 mission has revealed three possible Super-Earths around a nearby Sun-like star.

Discovery of boron on Mars adds to evidence for habitability

The discovery of boron on Mars gives scientists more clues about whether life could have ever existed on the planet, according to a new paper.
