Evidence is mounting that the same basic chemistry that made Earth habitable is unfolding, or once unfolded, on Mars. From ...

NASA announced the selection of industry proposals to advance technologies for the agency’s Habitable Worlds Observatory concept.

ESA's Jupiter Icy Moons Explorer (JUICE) is ultimately headed for the Jovian system, but on Aug. 20, it took a quick look at Earth. The spacecraft returned some very exciting news: the Earth is indeed ...

Fact-based stories from our cosmic neighbourhood, one star or constellation at a time. Name it, navigate it, know it.

Earth’s distant future has always been framed as a slow fade billions of years from now, but a new generation of models is painting a sharper and more unsettling picture. Instead of a gentle decline, ...

Astronomers think the most likely place to find life in the galaxy is on super-Earths, like Kepler-69c, seen in this artist's rendering. NASA Ames/JPL-CalTech Astronomers now routinely discover ...

Astronomers have analyzed the atmosphere of a nearby exoplanet and found that there are plenty of scenarios where it could have liquid water – and by extension, possibly life – on its surface. This ...

The number of potentially habitable planets is greater than previously thought, according to a new analysis by a Penn State researcher, and some of those planets are likely lurking around nearby stars ...

Astronomers have discovered a type of exoplanet called a “super-Earth” located in the habitable zone of its small star, and it’s right in our cosmic backyard, just 137 light-years away. The planet, ...

It took evolution 3 or 4 billion years to produce Homo sapiens. If the climate had completely failed just once in that time, then evolution would have come to a crashing halt, and we would not be here ...

Scientists think they’ve worked out what an Earth-like planet in our neighboring star system could look like. Astronomers are always hunting for exoplanets, which are just planets outside our Solar ...

A reanalysis of data from NASA's Kepler space telescope has revealed an Earth-size exoplanet orbiting in its star's habitable zone, the area around a star where a rocky planet could support liquid ...
