A newly identified Earth-sized exoplanet with a year-long orbit may lie near its star’s habitable zone, but extreme cold could limit its chances of hosting liquid water.

The planet is one of the best worlds for follow-up studies to determine whether it could be habitable or not.

Just decades after the first exoplanets were identified, our database of the distant worlds—monitored by the NASA Exoplanet Science Institute—has breached a new threshold. Now, astronomers have ...

An exoplanet called HD 137010 b might be the closest thing astronomers have ever seen to “Earth 2.0.” The trouble is that it’s only been seen once—and may never be glimpsed again ...
