The Milky Way likely has hundreds of millions of planets that are promising targets to probe for signs of life outside our solar system.

Researchers suggest a new way to expand the search for habitable planets that takes into account a zone not previously considered.

A new study presents the most detailed image ever of the inner region of planet forming disks that resemble dusty infrared donuts.

Regions on exoplanets called "terminator zones" could be prime sites for liquid water and possibly harbor life, a new study shows.

A newly-discovered Earth-sized exoplanet that could be capable of supporting life "is a key example that we have a lot more to learn."

Thanks to the new James Webb Space Telescope, astronomers are getting a clearer picture of an exoplanet about 700 light years away.

Planets may form differently around binary stars than they do near loners like our Sun. The finding could lead to new targets in the search for alien life.

The first ever look at a baby gas giant in its earliest stages provides evidence for a long-debated alternative theory of how Jupiter-like planets form.

Researchers conclude that only certain types of planets can form moons that are large in respect to their host planets. It could narrow the search for life.

"Eggshell planets" have an ultra-thin outer brittle layer and probably no plate tectonics. That raises questions about their habitability.
