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

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.

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

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

Scientists can’t agree why reefs in the Red Sea have long been immune to bleaching. The answer could be the key to saving these tough corals as climate change begins taking its toll.

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

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

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.

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.

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.

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.
