Scientists confirmed that Perseverance had discovered a rock that contained "complex organic matter," the building blocks of life.

Astronomers may have witnessed one of the rarest and most dramatic cosmic events ever seen: a long-sought intermediate-mass black hole ripping apart a dense white dwarf star and devouring it. The Einstein Probe space telescope caught the explosion in ...

Photo credit: NASA / Daniel Rutter Astronomers poring over years of data from NASA's planet-hunting satellite have confirmed a pair of worlds that rank among the largest and least dense ever detected. A sun-like star called TOI-791 hosts them both, . ...

At the right point of the orbit and stellar cycle, the star's chromosphere brightens.

Backyard astronomers will be able to use their telescopes to focus in on a massive cosmic visitor when it 'skims' past Earth this weekend.

The featherweight pair -- orbiting a star 1,110 light-years away -- are the biggest exoplanets found to have less density than cotton candy.

Black holes are a mainstay in sci-fi movies. How do these massive black holes, spread throughout our universe, actually work in real life?

Perseverance identifies organic carbon molecules in rocks on riverbed that carried water billions of years ago ...

Light from a galaxy that lived just 1.4 billion years after the Big Bang traveled more than 12 billion years to reach us. Astronomers examining long Hubble exposures of a deep sky field spotted something they had not expected to see at such an early ...
