Gallery: He Drew the Sun for 40 Years, But Now His Telescope Is Dying

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

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.

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.

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.

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

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

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

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.

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

“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.
