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.

Comet C/2025 A6 (Lemmon) is coming close to Earth, offering Californians a rare celestial viewing opportunity.

The rare interstellar comet 3I/ATLAS is under intense scrutiny as it passes through the solar system. Spacecraft like Hera, Europa Clipper, and JUICE are positioned to observe its unique 56,000 km ion tail.

A rare green comet is passing by Earth and can be seen with the naked eye from Oklahoma – and the next shot to catch it won’t come until the year 3375.

The comet C/2025 (SWAN) will be visible to the naked eye throughout the month, but will be most visible on October 21.

Asteroids, comets, and clouds contain complex organic molecules that form in space and might have kickstarted life on Earth and elsewhere.

The highly anticipated interstellar comet is currently invisible from Earth and completely hidden by the Sun's glare.
