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

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.

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.

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.

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.

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

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

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

“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.
