Solar Cycle 25 has surpassed its predecessor — but is the end in sight?

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

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.

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.

Astronomers have examined infant planets orbiting a star 370 light-years away, seeing the exomoon forming disks of gas and dust around them in unprecedented detail.

NASA's Lucy spacecraft will soon travel by asteroid Donaldjohanson, which formed roughly 150 million years ago.

The cosmic pinwheel that astronomers feared could one day shower Earth with lethal gamma rays may not be as dangerous as once thought.
