About 50 light-years from Earth, a gas giant about half the mass of Jupiter orbits a sunlike star. The discovery of Pegasi 51 b ushered in a new era of exoplanet research.

When evaluating possible planets out of the thousands out there, explained Prof. Bean, scientists look for liquid water as a main guiding principle. “All life on Earth needs liquid water, no matter ...

The Penn State team discovered the exoplanet using the Habitable-Zone Planet Finder (HPF), a high-resolution spectrometer at the McDonald Observatory in Texas that operates in the near-infrared ...

One hundred twenty light-years from us, there is an exoplanet that can potentially host life. It’s called K2-18b, and it’s ...

What if humanity could no longer live on Earth? Perhaps a catastrophic event forced us to find a new home among the stars.

Astronomers discovered GJ 251 c, a rocky planet four times Earth’s mass orbiting in its star’s habitable zone.

Scientists don't yet know whether GJ 251 c has an atmosphere, but new telescopes could reveal this within a decade.

If alien life exists on the newly discovered JG 251 c, we could know about it in the next 10 years.
