A visitor from another star system is creating excitement in the astronomy community. The comet 3I/ATLAS which was first spotted in July 2025 contains chemical clues that scientists can use to ...

Astronomers have caught what may be a rare cosmic catastrophe unfolding 11,000 light-years away. A seemingly ordinary sun-like star suddenly began flickering wildly, puzzling scientists until they ...

Cornell students reflect on the Artemis program seeking to return astronauts to the Moon and establish a sustained scientific presence there.

The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples could upend a major theory about how these extreme pairs form.

Astronomers have for the very first time watched the birth of a magnetar comprising the mass of 500,000 Earths squeezed inside a sphere measuring just 12 miles across.

An unusual flickering of a young F-type star called Gaia20ehk and an expanding cloud of dust around it suggest that a catastrophic planetary crash unfolded in real time, offering a rare glimpse of the ...

Tzanidakis was combing through old telescope data from 2020 when he found an otherwise boring star acting very strangely. The ...

In December 2024, astronomers watched a star around 25 times the mass of our sun die in a blaze of glory. Located one billion light-years from Earth, SN 2024afav was a prime example of a superluminous ...

Space scientist Maggie Aderin talks telescopes, neurodiversity and being underestimated with Rowan Hooper on the New ...

Analysis reveals what appears to be a channel of hot, low-density plasma stretching out from our solar system toward distant ...

New high-resolution simulations reveal that stellar rotation plays a crucial role in transporting material inside red giant stars.

Scientists are scrambling to explain why interstellar visitor 3I/ATLAS is carrying life's chemical building blocks at concentrations never before seen, and it makes its final pass through our cosmic n ...
