The most powerful solar flare of 2025 has launched a ball of energy toward Earth that could trigger widespread auroras across the northern half of the United States.

Astronomers using data from ESA's Euclid and Herschel space telescopes have confirmed that star formation has already peaked in the cosmos, and that the universe is bound to get steadily 'colder and deader' from here on.

An astronomer in Italy caught a fortuitous image of the bright comet Lemmon seemingly entwined with the glowing trail of a "shooting star."

The interstellar comet 3I/ATLAS is barreling toward its closest point to the sun as perihelion looms on Oct. 29. How different will it look when it reappears on the other side?

New telescope images show that the interstellar comet 3I/ATLAS is shooting a giant jet of gas and dust toward the sun. This is normal behavior for comets, an expert told Live Science.

The European Space Agency's ExoMars orbiter has captured the closest view yet of the interstellar comet 3I/ATLAS. The images reveal the comet's bright coma but show no signs of a tail.

The interstellar comet 3I/ATLAS does not come from our corner of the Milky Way, and may be a time capsule of the early galaxy, new research into its trajectory hints.

A small, giraffe-size asteroid called 2025 TF came closer to Earth than some satellites on Wednesday (Oct. 1), stunning astronomers who first spotted it hours later.

Scientists spotted an enormous black hole in the early universe that's growing at 2.4 times the theoretical Eddington limit. Studying it further could help answer one of the biggest questions in astrophysics.

Three years into its mission, the James Webb Space Telescope has advanced the search for alien life more than any machine before it. What will it find next?
