So far, humanity has yet to find its first "exomoon"—a moon orbiting a planet outside of the solar system. But that hasn't ...

Universe Today reports on a new telescope proposal that could help astronomers detect Earth-sized exomoons, explaining current limits, future technology, and why moons around distant planets matter ...

The discovery of the first potential exomoon has astronomers scratching their heads. It’s the size of Neptune, and its planet is the same size as Jupiter but ten times the mass. It’s also made of gas.

We have now confirmed the existence of over 4,000 exoplanets, or planets outside our solar system, which are teaching us about how planets and systems form and could even help us locate other ...

Astronomers have their fingers crossed that within the haul of data collected by NASA's Kepler mission, which has already detected nearly 3,000 possible exoplanets, hide the signatures of the very ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Do planets harbor life? Or is it their moons that are most ...

CAPE CANAVERAL, Fla. — For the first time, astronomers have discovered what could be an exomoon, a moon outside our solar system. The so-called exomoon, which is estimated to be the size of Neptune, ...

One of the most important and interesting questions science has to answer is: Are we alone? Trying to find other worlds that are habitable to life is not just an interesting topic—but serves as future ...

Reports of an exomoon’s death may have been greatly exaggerated. In late April, a trio of astronomers suggested that the best-yet candidate for an exomoon—a moon orbiting a world in another planetary ...

Even though the ingredients for life have been confirmed to be practically everywhere we look, the only world where we've definitively confirmed its existence is Earth. Exoplanet science has exploded ...

A new catalog aims to list all the known planets in the galaxy that could potentially be habitable to life. The count is at seven so far, with many more to come, researchers said. The online listing, ...
