There are plenty of ways to make the upcoming solar eclipse a fun learning experience for children.

Astronomers propose a new hypothetical planet, Planet Y, beyond Neptune, based on observed orbital anomalies in the Kuiper belt.

In 2017, astronomers found an object they’d never seen before. Now, it’s part of a growing category of elusive ‘dark comets’ – and we might find more soon.

This process, called accretion, is how everything in the solar system – planets, moons, comets and asteroids – came into being. Telescopes can see young solar systems being born.

Astronomy often focuses on objects that are vast distances from Earth – stars that are light-years away, galaxies that are ...

The star is surrounded by a protoplanetary disk, and this disk is the first evidence of debris condensing into what will eventually become planets and other objects. Observing this early phase of ...

NPR's Ari Shapiro talks with astronomer David Jewitt about what we can learn from the third interstellar object to have entered our solar system, a comet-like object known as 3I/ATLAS.

Weighing in at 0.6 solar mass, HOPS-315 should someday grow to become a star much like our own sun; this makes it a promising stand-in for studying the first stages of our solar system’s history. For ...

As the comet 3I/ATLAS through our Solar System, NASA's Hubble Space Telescope has captured the best look yet at the interstellar visitor.

Astronomers have spotted the birth of a new solar system for the very first time ever. Using the ALMA telescope and the James Webb Space Telescope, they observed the creation of the first specks ...
