June 3, 2025 — Astronomers have revealed new research showing that millions of new solar system objects are likely to be detected by a brand-new facility, which is expected to come online later this ...

An accidental discovery in an astronomy show offers researchers a new clue about the mysterious Oort Cloud, a large expanse of icy bodies revolving around the sun.

This makes one or more stellar passages the most likely cause of instability in the orbits of the solar planets for the next 4–4.5 Gyrs. Says Kaib: "[T]he approximation that the solar system is ...

It’s possible that this object was first ejected to the Oort cloud, the most distant region in our solar system, which is home to many comets, and then sent back,” Cheng adds. The size of 2017 ...

But this assumes that nothing affects the Solar System in the meantime, and that is not a certainty. As we travel around the galaxy, we might encounter stars, and even from a distance, they can ...

Astrophotographer Greg Meyer has captured a colorful view of the famous Trifid and Lagoon nebulas illuminated from within by ...

Astronomers have discovered that the Jupiter, the largest planet in our Solar System, was once so big that it could have held 2,000 Earths. Jupiter is our system's oldest planet, forming from the ...

So many unexplored secrets still lie at the outskirts of our solar system, where a potential candidate for a new dwarf planet lies. Although space beyond Neptune was thought to be mostly devoid of ...

If you were to look at a giant picture of space, zoom in on the Milky Way galaxy, and then zoom in again on one of its outer spiral arms, you’d find the solar system. Astronomers believe it ...

With binoculars or a wide-field scope, emission nebula IC 1396 is a vast playground, filled with many other interesting objects.

But it doesn’t end there. As more of the solar system has been explored and imaged, all kinds of geographical features have been mapped on many of our planets and satellites from Mercury to ...
