Interstellar comet 3I/ATLAS is briefly out of view as it travels around the sun this week, but researchers and amateur astronomers used spacecraft data to track its progress right up until perihelion.

Researchers armed with a new "photonic lantern" device have discovered an unexpectedly asymmetrical disk of gas swirling around a mysterious star 162 light-years from Earth. The new technology could revolutionize ground-based astronomy, the researchers claim.

New ESA simulations suggest that a solar storm on par with the 1859 Carrington Event could wreak havoc on Earth-orbiting satellites — and it is a question of "when," not "if" this will happen, experts say.

An early-stage study has found that a common chemotherapy drug disrupts lymphatic cells in the tissue surrounding the brain. This is linked to memory issues in mice.
