A bright new solar system comet could put on a show in the October night sky as it zooms past Earth.
Comet C/2025 R2 (SWAN) was discovered on Sept. 10 by Ukrainian amateur astronomer Vladimir Bezugly. It has brightened significantly since then, raising hopes that it could become a naked eye comet around the time that it makes its closest approach to Earth later this month on Oct. 21.
