Summary:
- Scientists have detected an X-ray glow from the interstellar comet 3I/ATLAS, which is a comet that originated from outside our solar system.
- This X-ray glow extends out to a distance of about 250,000 miles from the comet, which is much farther than the comet's visible tail.
- The X-ray glow is caused by the interaction between the comet's gases and the solar wind, which is a stream of charged particles flowing out from the Sun.
