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

Ape ancestors and early humans likely kissed their friends and sexual partners, according to a new study.

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.

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

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

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

CAPE CANAVERAL, Florida (Reuters) -The Blue Origin space venture of billionaire Jeff Bezos launched its giant New Glenn rocket from Florida on Thursday on its debut flight for paying customers, carrying two satellites on their way to Mars in the company's first NASA-scale science mission. The powerful two-stage rocket, ​standing 32 stories tall, blasted off from Cape Canaveral Space Force Station, marking the first mission flown by Blue Origin since New Glenn's inaugural test launch on January

After a weather delay dashed its first launch attempt over the weekend, Blue Origin’s New Glenn rocket has lifted off Thursday from Cape Canaveral, Florida.

Blue Origin launched its huge New Glenn rocket Thursday with a pair of NASA spacecraft destined for Mars. It was only the second flight of the rocket that Jeff Bezos’ company and NASA are counting on to get people and supplies to the moon — and it was a complete success. The 321-foot (98-meter) New Glenn blasted into the afternoon sky from Cape Canaveral Space Force Station, sending NASA’s twin Mars orbiters on a drawn-out journey to the red planet.
