Gregg, a Ph.D. candidate in physics and astronomy, developed a computer model to study our solar system, Alpha Centauri and the interstellar activity—the movement of gas, dust and other space ...

All eyes are on Comet 3I/ATLAS as astronomers worldwide chase the exotic ice ball through our solar system ...

Trans-Neptunian objects (TNO) are some of our solar system's lesser-known objects. They number in the thousands, and they get ...

I/ATLAS might be over 7 billion years old, a new study reports, which would make it the oldest comet known. But experts caution we need more data.

The Colorado Scale Model Solar System depicts the Sun, the planets, and the distances between them all on the same scale of 1 to 10 billion. That is, the real objects and distances are 10 billion ...

I came across an interactive NASA tool called Solar System Simulator. On it, you can view objects in our solar system from different viewpoints and moments in time. Fill out each drop down menu ...

After defending his PhD thesis on modeling interstellar objects on Monday, June 30, Matthew Hopkins intended to take some ...

These briefly-captured interstellar objects may make up a sizeable chunk of the Oort Cloud, the hypothetical cloud of icy objects surrounding the farthest outskirts of our Solar System.

Researchers at Oxford have discovered that comet 3I/ATLAS may be over 7 billion years old, making it the oldest one we've ...

Our solar system may not be as isolated as we once thought. According to a new study, more than 1 million interstellar objects could be lurking in the outer reaches of our cosmic neighborhood ...

Galactic hitchhikers visiting our solar system, if theyexist, would probably love to get their hands on a new guide that puts GPS toshame. A planetary scientist has made the most detailed maps of ...
