Researcher Matthew Graham said scientists didn't initially "believe the numbers about the energy" emitting from the cosmic display.

Scientists working in Mexico have recorded multiple incidents in which a group of orcas hunt young great white sharks and eat their energy-rich livers.

Dark matter obeys gravity after all — could that rule out a 5th fundamental force in the universe?

China's Shenzhou 20 and 21 astronauts enjoyed freshly cooked BBQ aboard the Tiangong space station recently, thanks to a new microgravity oven.

Paleontologists spotted injuries on the tails of duck-billed dinosaur fossils that might have occurred during mating.

"This discovery ends a protracted search for these waves that has its origins in the 1940s."

The brief flashes were captured from Earth and could be from the Taurid meteor shower.

Multiple NASA missions captured images as an interstellar comet zoomed by Mars in October.

NASA released new images of the interstellar comet 3I/ATLAS — just the third cosmic visitor from elsewhere in the galaxy ever confirmed — on Wednesday.

NASA unveiled close-up pictures on Wednesday of the interstellar comet that’s making a quick one-and-done tour of the solar system. Discovered over the summer, the comet known as 3I/Atlas is only the third confirmed object to visit our corner of the cosmos from another star. Three NASA spacecraft on and near the red planet zoomed in on the comet as it passed just 18 million miles (29 million kilometers) away, revealing a fuzzy white blob.

Astronomer Gianluca Masi captured breathtaking imagery of solar system comet C/2025 K1 (ATLAS) breaking into multiple pieces after being warmed by the sun.

This image shows Euclid's capability to explore both our cosmic neighborhood and the deep universe beyond.

The world's climate leaders are conceding that Earth's warming will shoot past a hard limit they set a decade ago in hopes of keeping the planet out of a danger zone. United Nations officials, scientists, and analysts are pinning their hopes on eventually forcing global temperatures back below the red line they set in the 2015 Paris Agreement, which sought to limit warming to 1.5 degrees Celsius (2.7 Fahrenheit) since preindustrial times. In the way climate science uses the term, it doesn't me
