Gallery: Mesmerizing Photos Capture the Flight Patterns of Birds

I’ve spent years testing smart bird feeders. These are the currently discounted models I’d buy for myself—or give as gifts.

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

As coastlines change, so do surf breaks. That may spell the end for premier waves and the tourist economies that depend on them.

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

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

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.

Redwoods adapted to a cool, foggy climate. Now a new study shows they slow down photosynthesis when their environment warms.

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

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

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.

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.

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.
