Interstellar comet 3I/ATLAS shines in the sharpest view yet captured by the Hubble Space Telescope, helping astronomers determine the object’s size.

The Hubble Space Telescope has captured a stunning image of a high-speed comet traveling through our solar system. Scientists say the comet poses no danger to the Earth, and Hubble’s observations will help them learn more about this interstellar visitor.

These strange objects could explain how water arrived on Earth, but may also be a previously unrecognised threat to our planet. Now, a spacecraft is headed towards one to investigate.
