A stunning new image from the NASA/ESA/CSA James Webb Space Telescope reveals a comet-shaped cloud in the Carina Nebula hiding a cluster of about 70 young stars, including a rare giant of O-type nearly 19 times as massive as the Sun. This Webb image shows the Treasure Chest, a cometary globule located within the famous Carina Nebula. Image credit: NASA / ESA / CSA / Webb / M. Reiter / M.H. Özsaraç. The...

Planetary researchers analyzing images from NASA’s New Horizons spacecraft have found evidence that liquid nitrogen may still be seeping up from beneath the dwarf planet’s giant glacier, Sputnik Planitia, marking the first suggested case of recently flowing liquid on Pluto’s surface. This Pluto mosaic was made from New Horizons LORRI images taken on July 14, 2015, from a distance of 49,700...

Archaeologists in southwestern Germany have unearthed two miniature bird figurines carved from mammoth ivory, among the smallest and most delicate examples of Ice Age art ever found.

The two ancient figurines, roughly 2 cm (0.8 inches) long and weighing...

Dinosaurs evolved into some of the largest animals ever to walk the Earth, but a new mathematical model suggests that early mammals may have crowded them out of the ecological niches reserved for the smallest creatures.

Using the largest sample yet of particles called beauty mesons, physicists with the CMS Collaboration at CERN’s Large Hadron Collider (LHC) refined a decades-old test of the subtle imbalance that let our Universe exist at all. Neutral beauty mesons can turn into their own antimatter opposite and back again. Image credit: Ansar Iqbal / CMS. One of the greatest mysteries in physics is why the Universe...

In a perspective paper published in The American Journal of Clinical Nutrition, a team of researchers and health experts calls for a ‘paradigm shift’ in how public health agencies address hypertension, which affects more than 1.28 billion adults worldwide and remains a leading driver of cardiovascular disease. The authors say high blood pressure can be controlled better with a strategy that combines...

Neanderthals vanished roughly 42,000 years ago, but a piece of their biology appears to be quietly at work in some people today, according to a new study led by scientists from the Max Planck Institute for Evolutionary Anthropology. Aspects of Neanderthal anatomy live on in people today. Image credit: Holger Neumann / Neanderthal Museum. “Neanderthals are the most well-known among archaic human...

Zircon crystals and impact-altered minerals show that a massive asteroid slammed into what is now the Pilbara region of Western Australia about 3 billion years ago. The North Pole Dome crater: (A) simplified map of the East Pilbara Terrane (EPT, Western Australia), showing Paleoarchean granite domes (pink) and greenstone belts (greens and blues); the North Pole Dome (NPD) lies near the terrane center;...
