New high-contrast images from SPHERE show a stunning variety of debris disks shaped by collisions of tiny planet-building ...

Observations with the instrument SPHERE at ESO's Very Large Telescope have produced an unprecedented gallery of "debris disks" in exoplanetary systems.

Still, science being science, we needed proof—and we got it in 1992, when two astronomers found two planets orbiting a pulsar ...

Roughly four and a half billion years ago the planet Theia slammed into Earth, destroying Theia, melting large fractions of Earth’s mantle and ejecting a huge debris disk that later formed the moon.

"We reported hints of methane, but the question is, 'is the methane attributable to molecules in the atmosphere of the planet ...

Theia, the world that helped form the Moon, came from the Solar System. Chemical clues in Earth and Moon rocks reveal this close origin.

Later in December, the 3I/ATLAS interstellar comet will get as close to Earth as it ever will. Here's what to know.

A collision between Earth and a massive Mars-sized protoplanet likely caused the formation of our moon. Now scientists from the Max Planck Institute suggest that doomed planet was likely a rowdy ...

Across the galaxy, astronomers now see that planetary systems fall into four broad classes, and our own solar system, part of the rare Ordered group, is only one of them. At the same time, discoveries ...

Time moves differently on Mars. NIST physicts recently calculated exactly how fast each second passes on Mars. And if humans want to explore the solar system, every microsecond counts.

Astronomers have spotted an intriguing cluster of objects in the Kuiper belt, the enormous, donut-shaped region of icy objects beyond the orbit of Neptune. This latest “inner kernel” was identified by ...

More research is needed before scientists can determine whether the recently observed methane signatures point to the presence of an atmosphere or are simply the result of contamination from the host ...
