Comets

Comet Nishimura, which was only discovered in August, has survived its closest approach to the sun and will brighten over the next week. But is it still visible from Earth?

The comet Nishimura, which was only discovered in August, will soon be slingshotted around the sun and back out toward the edge of the solar system where it will remain for centuries.

Comet Nishimura has a hyperbolic orbit, which suggests that it may have come from outside the solar system and will likely be catapulted into interstellar space after slingshotting around the sun.

The exploding comet, known as 12P/Pons–Brooks, is currently approaching its closest point to Earth during its 71-year orbit through the solar system.

Astronomers accurately predicted that the icy volcanic comet 29P would erupt after noticing changes in its brightness leading up to its latest explosion.

Astronomers have spotted water that looks remarkably similar to our own in orbit around a young star 1,300 light years from Earth.

The newly discovered comet C/2023 A3 is making a close approach around the sun for the first time in 80,000 years, and might be as bright as a star in fall 2024.

Tonight (Feb. 1), the green comet C/2022 E3 ZTF will make its closest approach to Earth since the age of the Neanderthals. Here's how to view it.

The green comet C/2022 E3 (ZTF) will make a close approach to Earth on Feb. 1/Feb. 2 before sailing off into deep space, possibly never to return.

C/2022 E3 (ZTF), a comet that has recently made headlines as it flies closer to Earth, briefly developed an ethereal third tail thanks to a weird optical illusion.
