This week, the Pentagon released a full-resolution image of the vehicle, the capabilities of which remain rather mysterious.

Lying beyond Pluto, 2026 ED138 could be as large as 1,500 kilometers in diameter. Astronomers are still working to confirm whether it meets the criteria for a dwarf planet.

The data drop includes photographs, audio, video, and astronauts’ notes that will be used to study the moon and prepare for future human missions.

The new image isn’t just stunning—it may also provide clues about how this star survived its own explosion.

Made up of small fragments left behind by Halley’s Comet, these meteors are known for being especially bright and speedy.

A global network of detectors are reporting some of the most substantial measurements yet of neutrinos created deep underground by the radioactive elements that power our planet’s tectonic activity.

These elusive and reactive particles have been challenging to hold on to and even more challenging to study, but a new method paves the way for tests on the differences between matter and antimatter.

The Webb telescope sees tiny red dots everywhere. Astronomers can’t agree on what they are, but some believe they may be enormous stars with black holes inside.

Castelion—a next-generation defense tech company—is building a facility in Rio Rancho Estates that documents show could pose a major fire and chemical hazard to neighboring communities.

Bluesky tells WIRED it blocked links to a leaked archive of information on 41,000 ICE, CBP, and other DHS workers because it contains people’s contact information, shared without their authorization.

Under 1 million years old, “Elias 2-24b” is now the youngest exoplanet ever observed, and it may force researchers to reevaluate theories about how planets are formed.

Two orbiters have long outlasted their expected lifespans and completely reshaped our understanding of the Red Planet, all while operating 140 million miles from Earth.
