With more than 4,000 exoplanets—planets orbiting stars other than our sun—discovered so far, it may seem like we are on the cusp of finding out whether we are alone in the universe. Sadly though, we don't know much about ...

A team of researchers from several European countries and one from Chile has found evidence of three possibly habitable exoplanets circling the star GJ1061. In their paper uploaded to the arXiv preprint server, and soon to ...
In the search for life beyond our galaxy, many scientists have their eyes turned toward orbs like Earth: rocky planets. So after the Transiting Exoplanet Survey Satellite (TESS) detected a rocky planet slightly larger than ...

Even though Earth has been habitable (has had surface liquid water and some crust) for 4.3 billion years, and the oldest putative traces of life suggested go back up to 4.1 billion years, the presence of a microbial biosphere ...

A new study provides the most accurate estimate of the frequency that planets that are similar to Earth in size and in distance from their host star occur around stars similar to our Sun. Knowing the rate that these potentially ...

A super-scorched planet orbiting around a nearby dim star has helped reveal the presence of two previously unseen planets—one of which could host liquid water and thus be friendly to life, astronomers say.

Icy planets once thought too cold to support life might have livable land areas above freezing, challenging the typical assumption of what kinds of planets might be habitable, a new study suggests.
