Gallery: At the Bottom of the Sea, Glass Spheres Prepare to Hunt for Mysterious Neutrinos

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.

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

“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.

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

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.

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.

Optogenetics revolutionized neuroscience, but its origins come from an entirely brainless organism—an alga.

Researchers took lessons from nocturnal animals to help rescue drones overcome a key challenge: flying in the dark.

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.

While oil is known to float, new research finds that over time it can permeate even extremely deep marine habitats, with animal populations declining by as much as 80 percent.

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 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.
