There are only a few days left to watch the Zuchinshan-Atlas comet in the evening sky (streaming recording)

The comet discovered at the same time by two automatic stargazers and named after both is extremely bright. It will return to Earth's proximity only in 80 thousand years

The Webb Space Telescope finds an abundance of carbon molecules around a young star

"It's amazing that we can detect and quantify the amount of molecules we know very well on Earth, like benzene, which is actually more than 600 light-years away," said one of the authors of the paper that appeared.

This figure illustrates how an interstellar object is rapidly approaching our solar system. Ejected from its home planet system long ago, the object traveled through interstellar space for billions of years before passing briefly in our cosmic neighborhood. The Robin Observatory will reveal many of these unknown interstellar visitors.

Visitors from distant stars: The Rubin Observatory will detect a multitude of interstellar objects moving through our solar system

The Vera Rubin Observatory's Legacy Survey of Space and Time (LSST) will revolutionize solar system science by discovering a population of previously undiscovered interstellar comets and asteroids passing through the neighborhood

The Green Comet C/2022 E3: How to watch the rare visitor

Green Comet C/2022 E3 (ZTF) will approach Earth on February 1st and, although pale in the northern sky, will be seen near the carts/bears before sailing into deep space for millions of years if at all
