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

Blue Origin's powerful New Glenn rocket just aced its second-ever mission —and returned to Earth safely for the first time. See a video of the booster's dramatic homecoming here.

Scientists have recovered RNA from a mammoth carcass preserved in permafrost for 40,000 years. The ancient molecules reveal details about the creature’s last moments.

On Episode 186 of This Week In Space, Rod Pyle and Tariq Malik talk with Dr. Jim Green, NASA's former chief scientist, about snow on the moon.

Paleontologists have discovered fossil remains belonging to an enormous ‘toothed’ bird that lived for a period of about 60 million years after dinosaurs.

Birds and dinosaurs lived together for millions of years, but only toothless birds survived the asteroid impact that upended life on Earth.

Researchers have newly described three extremely rare species of toad that leapfrog over the egg-to-tadpole stage and give birth to toadlets.

The behavior, which had never been observed before, stunned scientists as, typically, the larger house spider would prey on its smaller neighbor.

Jeff Bezos’s aerospace company Blue Origin is now the second, after SpaceX, to land a rocket booster for reuse.

A communications researcher lays out the dynamics of conspiracy theory belief and why they gain traction in times of anxiety and uncertainty.

By Will Dunham WASHINGTON (Reuters) -Dogs today come in a mind-blowing array of shapes and sizes, from the diminutive pug, Pekingese and Pomeranian to the grand Irish Wolfhound, Great Dane and Saint

A peek inside some leading research labs shows how scientists-turned-detectives are painstakingly decoding what causes autoimmune diseases and how to stop the immune system from attacking you instead of protecting you. Researchers use laser-powered machinery and brightly colored fluorescent dyes to tell rogue cells from normal ones. Take Type 1 diabetes, caused when cells in the pancreas that produce insulin are gradually killed off by rogue T cells.

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.

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.

Scientists may have solved the mystery of an "impossible" merger between two black holes so massive and fast-spinning that they shouldn't even exist, according to current theory.

Scientists say they have unearthed Australia’s oldest known crocodile eggshells, potentially shedding light on ancient reptiles called “drop crocs.”

Three solar storms reached Earth this week, triggering colorful auroras in unexpected places.
