This year, astronomers discovered more than 100 previously unknown moons in our own solar system. There may be many more yet to be discovered, and cataloguing them could help us better understand how ...

The giant planets weren't always where we find them today. Jupiter, Saturn, Uranus and Neptune formed in a more compact configuration and later underwent a violent reshuffling that scattered them to ...

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...

The comet is the third object ever confirmed to have entered our cosmic neighborhood from elsewhere in the galaxy. Space telescopes and orbiters have been documenting the rare visit. A mysterious ...

Earth has the perfect combination of a livable atmosphere and a protective magnetic field that prevents the Sun's harmful radiation and radioactive solar winds from damaging us, allowing us to live on ...

New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple ...

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 ...

NASA’s Goddard Space Flight Center shared the images of comet 3I/ATLAS. It's possibly as big as Manhattan, likely older than our own solar system and it's traveling through space at speeds of up to ...

NASA unveiled close-up pictures on Wednesday of the interstellar comet that's making a quick one-and-done tour of the solar system. Discovered over the summer, the comet known as 3I/Atlas is only the ...

Our solar system is speeding through space much faster than previously thought, challenging the fundamental assumptions that have long shaped our understanding of the cosmos. That’s according to ...

Our solar system appears to be breaking the cosmic speed limit, according to new research from Bielefeld University, casting fresh doubt on the Standard Model of Cosmology. “Our analysis shows that ...
