Every few years, something strange drifts into our solar system. However, this object is not from the family of the Sun’s planets, asteroids, or comets. Instead, it comes from the vast darkness of ...

Rogue objects, also known as interstellar objects, are celestial bodies that wander through space without being gravitationally bound to any star system. Unlike planets, asteroids, or comets within ...

Astronomers have spotted 3I/ATLAS, just the third interstellar object ever seen in our solar system. Bigger, faster, and possibly far older than ‘Oumuamua or Borisov, this icy traveler could help ...

Called 3I/ATLAS, the object is only the third of its kind known to astronomers, and it’s likely been heading our way for billions of years, carrying pristine material from another star system Jay ...

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. A remarkable ...

Astronomers have uncovered a massive new trans-Neptunian object, 2017 OF201, lurking at the edge of our solar system. With an orbit stretching 25,000 years and a size that may qualify it as a dwarf ...

Objects such as 'Oumuamua, Borisov and recently 3I/ATLAS have opened our eyes to the reality that outsiders regularly visit our solar system — and we're about to start spotting a whole lot more of ...

It comes down to the speed at which these objects were moving during their formation, and the strength with which their constituent particles interlocked. When you purchase through links on our site, ...

The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...

It may not feel like it, but everything in the universe is in constant motion. Our Sun, with all its planets, orbits the center of the Milky Way, flying through the cosmos at around 450,000 miles per ...

The Solar System is the name given to the part of space that surrounds the Sun. Even though it is bigger than anything we can imagine, the Solar System is actually a very tiny part of the universe.
