The first image of the behemoth at the center of our galaxy opens new avenues for understanding the nature of black holes

Astronomers announced a new exomoon candidate orbiting an exoplanet about 5,400 light-years from Earth. It is the latest possible exomoon

Astronomer David Kipping and his Cool Worlds Lab at Columbia find an exomoon signal in archival data, hinting at the possibility of more exomoon discoveries to come.

Whats believed to be an exomoon - a moon outside our solar system - is orbiting a Jupiter-sized planet called Kepler 1708b, say scientists at Columbia University in New York.

ASTRONOMERS believe they may have found a second supermoon 5500 light years away which is orbiting a planet the size of Jupiter.

Astronomers have reported a second, super-sized moon orbiting a Jupiter-sized planet beyond our solar system.

The red dwarf star TRAPPIST-1 is home to the largest group of roughly Earth-size planets ever found in a single stellar system. Located about 40 light-years away, these seven rocky siblings provide an example of the tremendous variety of planetary systems that likely fill the universe. A new study published in the Planetary Science Journal shows that the TRAPPIST-1 planets have remarkably similar densities. Th...

Washington: The seven rocky planets orbiting the the red dwarf star TRAPPIST-1 have remarkably similar densities, which provides clues about their composition.
