Dark energy may have a completely unknown aspect of physics acting as an accomplice in its efforts to defy gravity, suppressing the growth of large-scale structures like galaxy superclusters.

The nova is ignited when a "vampirific" white dwarf steals too much matter from a companion star.

A group of stellar Sherlocks have solved the mystery of red transient objects that appear and fade in the sky, linking them to the total explosive death of stars.

Using the James Webb Space Telescope, astronomers have captured direct images of Neptune's elusive auroras for the first time.

This new moon of March 2025 will create a partial solar eclipse visible in the northeastern part of North America, much of Europe and Russia.

While the presence of these molecules is not proof of ancient life on Mars, scientists say it shows we could detect chemical signatures of past life, if it ever existed.

The observation of titanic jets emerging from the supermassive black hole at the heart of a distant galaxy could be a grim prediction of the Milky Way's future.

Using data from the Euclid Space Telescope, astronomers have discovered a stunning 2,674 dwarf galaxies, the study of which could help better understand cosmic evolution.

A new recipe for black holes could do away with central singularities, saving the laws of physics from troubling infinities.

JWST could potentially detect the signature of methyl halide compounds, produced by microbial life in Earth's ocean, on hypothetical hycean exoplanets.
