A sequence of events during the evolution of certain rocky planets orbiting M-dwarfs, the most common stars in the universe, creates an atmosphere that would be stable over time. This is true for more ...

Scientists have been exploring the evolution of our universe for decades, trying to gain a better understanding of the cosmic phenomenon exhibited by the celestial bodies that occupy space. They've ...

If you look across space with a telescope, you'll see countless galaxies, most of which host large central black holes, ...

When you think of a planet, you probably think of one of the planets in our own solar system, like Earth, Jupiter, or Mars. Most of the exoplanets we’ve discovered have been like those in our solar ...

Across the galaxy, astronomers now see that planetary systems fall into four broad classes, and our own solar system, part of the rare Ordered group, is only one of them. At the same time, discoveries ...

Planets are about as scarce as they can be in our summer evening sky. Earth is the only one that’s visible as darkness falls. Just look down instead of up. All of the major planets that are visible to ...

(CNN) — Astronomers are questioning the theories of planet formation after discovering an exoplanet that technically shouldn’t exist. The planet, about the mass of Neptune and more than 13 times as ...

Earth-like planets orbiting close to small stars probably have magnetic fields that protect them from stellar radiation and help maintain surface conditions that could be conducive to life, according ...

For centuries our solar system was the only planetary system known to humans. We had no proof other worlds existed beyond those in our own cosmic backyard, and we imagined that if other planetary ...

Water worlds could be surprisingly common in our galaxy — but they probably don’t look like you expect. If we find evidence of life on alien worlds, it will probably be on a planet somewhere between ...

A star about 600 light-years away is giving astronomers a front-row view to the environments in which rocky planets like Earth form around the most abundant stars in the universe. Called ISO-ChaI 147, ...
