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.

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.

“Detecting a neutrino is like looking for a needle in a haystack,” says Juan Carlos Díaz Vélez, who breaks down why researchers are looking for the cosmic particles under the Antarctic ice.

Astronomers find that a white dwarf’s density and the kind of material it absorbed from its surroundings can produce a rainbow of shades in the star’s atmosphere.

JAXA is leading an international mission to reach Mars’ Phobos moon and bring soil back to Earth. If successful, it could unlock new clues about the history of the solar system.

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.

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.

The cloud has baffled astronomers since its discovery in 2018. Now, a new study offers a possible cause for its appearance.

Though scaled back from initial plans of landing, the voyage will serve as a dress rehearsal for when humans return to the moon’s surface.

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.

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

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