The James Webb Space Telescope found "tiny red dots" in the early universe representing overgrown supermassive black holes and stars that are impossibly old for the infant cosmos.

The Astronomy Photographer of the Year contest has revealed the jaw-dropping finalists of its 2024 competition.

New photos from the European Space Agency's Mars Express orbiter give us our best look yet at a giant ravine on the Red Planet. The dark "scar" was likely birthed by a gigantic blob of magma hidden beneath a massive nearby volcano millions of years ago.

New infrared images showcase "fire-breathing" lakes all across the surface of Jupiter's volcanic moon Io.

The vibrant auroras from earlier this year have a darker side that scientists are still uncovering.

A new paper suggests that we may be able to spot alien spaceships hopping between distant stars using "warp drives" because the sci-fi-inspired technology would give off specific gravitational waves that are unlike anything else we know about.

Astronomers have just discovered two dwarf galaxy candidates orbiting our galaxy. The orientation of these entities suggests there could be up to 500 similar stellar clusters circling the Milky Way, which is more than double previous estimates.

Summer is the best time to see the Milky Way in the Northern Hemisphere without a telescope. The key is to find clear, dark skies on moonless nights.

China's Chang'e 6 mission return capsule has been transferred to Beijing and opened to access its precious cargo — samples from the moon's mysterious far side.

A new multiwavelength 3D visualization of the iconic "Pillars of Creation" showcases the differences between Hubble and James Webb Space Telescope data.
