Ancient plants reveal that the vestiges of the North American ice sheet started expanding a few thousand years ago, but that climate change caused it to reverse course.

“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.

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.

Seven of 16 planetary vital signs are in their most extreme state ever recorded, and El Niño is here to make matters even worse.

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

Scientists left structures up to 100 meters under the surface. Here’s what they found when they retrieved them 10 years later.

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.

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.

Here’s what we know about the record-setting El Niño on a record-hot planet, and the most important questions scientists are trying to answer.

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