Experts have discovered more than 4,000 exoplanets, but an exomoon has yet to be definitely discovered, despite the 2018 announcement there was something orbiting Kepler-1625b. But now, researchers ...

Forget about love. Scientists want to know: Are we looking for life in the wrong places? An astrophysicist at the U.K.'s University of Lincoln says that exomoons, moons which orbit planets outside of ...

There are eight planets in our Solar System (sorry Pluto), but collectively, these planets host over 175 moons, one or two of which may even harbor life. Indeed, our galaxy, based on what we observe ...

A reddish striped planet is seen next to a smaller orb that's blueish. The two objects are set against a dark background representing space. New research has a duo of scientists channeling Obi-Wan ...

This article was originally published at The Conversation. The publication contributed the article to Space.com's Expert Voices: Op-Ed & Insights. When I was young, the only planets we knew about were ...

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 ...

The extrasolar planets Kepler-1625b and Kepler-1708b are supposedly the home worlds of the first known exomoons. A new study now comes to a different conclusion. Only two of the more than 5300 known ...

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 ...

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 ...

Bright, young planets that are still hot from their formation could shine some light on their moons, making the dim satellites easier for astronomers to spot using a newly developed technique. The new ...

Solar systems in the midst of their death throes may offer planetary scientists a chance to search for surface life on their far-flung surface moons, says a new paper. The idea is that after sunlike ...

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 ...
