Astronomers have identified 3I/ATLAS, an ancient, ice-rich interstellar comet potentially older than our solar system.

The comet is on what’s known as a hyperbolic trajectory, which means that it doesn’t follow an orbital path around the sun.

Typically, telescopes are synonymous with bringing far-off objects close, but the newest member of the solar system was discovered using wide-field imaging. The Subaru Telescope has spotted a distant ...

An interstellar comet that originated outside our solar system just flew by the sun. Next, the object will fly by Earth in December.

As 3I/Atlas neared its closest point to the sun in its orbit, the internet was abuzz with curiosity about the comet.

This point, known as perihelion, was around 210 million kilometers from the sun, or 1.4 times the distance between the sun ...
