In August astronomers announced that the nearby star Proxima Centauri hosts an Earth-sized planet (called Proxima b) in its habitable zone. At first glance, Proxima Centauri seems nothing like our Sun ...

Alpha Centauri, one of the two "Pointer Stars" that help stargazers find the Southern Cross in the Southern Hemisphere, may have a planet in orbit around it. If it does, the Webb Telescope will find ...

A team of astronomers using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) in Chile have found evidence of another planet orbiting Proxima Centauri, the closest star to our Solar ...

Within a few dozen light years of the Sun, the sky is crowded with stars that could, in principle, host living worlds. I want ...

The closest star to Earth, Proxima Centauri (PC), is still about 8000 times further away from us than Pluto. Propelling a probe to PC will require a much higher cruising speed than we can currently ...

The Extremely Large Telescope (ELT), currently under construction in northern Chile, will give us a better view of the Milky Way than any ground-based telescope before it. It's difficult to overstate ...

What can star variability—changes in a star's brightness over time—teach astronomers about exoplanet habitability? This is what a recent study accepted for publication in The Astronomical Journal ...
