A remarkable new fossil from China reveals for the first time that a group of reptiles were already using whale-like filter feeding 250 million years ago.

New observations and simulations of three spiral arms of gas feeding material to three protostars forming in a trinary system have clarified the formation of multi-star systems.

A subpolar species associated with Atlantic water expanded far into the Arctic Ocean during the Last Interglacial, analysis of microfossil content of sediment cores reveals. This implies that summers in the Arctic were ice free during this period.

New research details the discovery of the highest-energy light ever observed from the sun. The international team behind the discovery also found that this type of light, known as gamma rays, is surprisingly bright. That is, there's more of it than scientists had previously anticipated.

An international team of scientists have discovered an unusual Jupiter-sized planet orbiting a low-mass star called TOI-4860, located in the Corvus constellation.

NASA's James Webb Space Telescope has recorded breath-taking new images of the iconic Ring Nebula, also known as Messier 57.

A new image of the galaxy cluster known as 'El Gordo' is revealing distant and dusty objects never seen before, and providing a bounty of fresh science. The infrared image displays a variety of unusual, distorted background galaxies that were only hinted at in previous Hubble Space Telescope images.

Royal Ontario Museum announces the oldest swimming jellyfish in the fossil record with the newly named Burgessomedusa phasmiformis. This 505-million-year-old swimming jellyfish from the Burgess Shale highlights diversity in the Cambrian ecosystem.

The origin of bees is tens of millions of years older than most previous estimates, a new study shows. A team led by Washington State University researchers traced the bee genealogy back more than 120 million years to an ancient supercontinent, Gondwana, which included today's continents of Africa and South America.

A young planet whirling around a petulant red dwarf star is changing in unpredictable ways orbit-by-orbit. It is so close to its parent star that it experiences a consistent, torrential blast of energy, which evaporates its hydrogen atmosphere -- causing it to puff off the planet.

Many people know that stars appear to twinkle because our atmosphere bends starlight as it travels to Earth. But stars also have an innate 'twinkle' -- caused by rippling waves of gas on their surfaces -- that is imperceptible to current Earth-bound telescopes. In a new study, researchers developed the first 3D simulations of energy rippling from a massive star's core to its outer surface. Using these new models, the researchers determined, for the first time, how much stars should innately twinkle.

Some organisms, such as tardigrades, rotifers, and nematodes, can survive harsh conditions by entering a dormant state known as 'cryptobiosis.' In 2018, researchers found two roundworms (nematode) species in the Siberian Permafrost. Radiocarbon dating indicated that the nematode individuals have remained in cryptobiosis since the late Pleistocene, about 46,000 years ago. Researchers have now used genome sequencing, assembly, and phylogenetic analysis and found that the permafrost nematode belongs to a previously undescribed species, Panagrolaimus kolymaensis.

As the next generation of giant, high-powered observatories begin to come online, a new study suggests that their instruments may offer scientists an unparalleled opportunity to discern what weather may be like on far-away exoplanets.

Young stars are rambunctious! NASA's James Webb Space Telescope has captured the 'antics' of a pair of actively forming young stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. To find them, trace the bright pink and red diffraction spikes until you hit the center: The stars are within the orange-white splotch. They are buried deeply in a disk of gas and dust that feeds their growth as they continue to gain mass. The disk is not visible, but its shadow can be seen in the two dark, conical regions surrounding the central stars.

Astronomers have discovered new evidence of how planets as massive as Jupiter can form.

An international team of scientists, including astrophysicists, report on a dedicated observational campaign on the Galactic microquasar dubbed GRS 1915+105. The team revealed features of a microquasar system that have never before been seen. Using the massive Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China, astronomers discovered a quasi-periodic oscillation (QPO) signal in the radio band for the first time from any microquasar systems.

The spiral galaxy NGC 1532, also known as Haley's Coronet, is caught in a lopsided tug of war with its smaller neighbor, the dwarf galaxy NGC 1531.

Researchers have described a new species of armored reptile that lived near the time of the first appearance of dinosaurs. With bony plates on its backbone, this archosaur fossil reveals that armor was a boomerang trait in the story of dinosaur and pterosaur evolution: the group's ancestors were armored, but this characteristic was lost and then independently re-evolved multiple times later among specialized dinosaurs like ankylosaurs, stegosaurs, and others.

Miyako Islands are home to various native species of snake and lizards. How these species came to call these islands home has long puzzled scientists. A group of researchers have compiled the latest geological and biological data, proposing that an island once facilitated migration between Okinawa and Miyako Islands.
