A Huge Comet Is About to Become Visible in the Sky

In October, a newly discovered comet will streak so close to Earth that people may be able to make out its heavenly fireworks with the naked eye - a spectacle that won't happen again for more than a millennium, according to Space.com, so it's worth trying to spot it. This icy interstellar visitor, now given the clunky name of C/2025 R2 (SWAN), is estimated to make its closest approach to Earth at a mere 25.10 million miles away on around October 21, Space.com reports.
