Since fast radio bursts (FRBs) were first discovered over a decade ago, scientists have puzzled over what could be generating these intense flashes of radio waves from outside of our galaxy. In a gradual process of elimination, the field of possible explanations has narrowed as new pieces of information...
Gray wolves are among the largest predators to have survived the extinction at the end of the last ice age around 11,700 years ago. Today, they can be found roaming Yukon’s boreal forest and tundra, with caribou and moose as their main sources of food. A new study led by...
The SwRI-led Ultraviolet Spectrograph (UVS) orbiting Jupiter aboard NASA's Juno spacecraft has detected new faint aurora features, characterized by ring-like emissions, which expand rapidly over time. SwRI scientists determined that charged particles coming from the edge of Jupiter's massive magnetosphere triggered these auroral emissions. "We think these newly discovered faint...
AT FIRST, the scene at DeGray Lake in Arkansas looked like a massacre. In 1994, 29 bald eagles were found dead nearby. It was the biggest undiagnosed die-off of bald eagles in history, and it was only getting started. By 1996, at least 70 eagles had died across several Arkansas...
A team of international scientists that includes a Canadian researcher said it has mapped, for the first time, the magnetic fields surrounding a black hole. The Event Horizon Telescope Collaboration team produced an image that shows electromagnetic fields that look like a "crisp swirl" of light around the black hole...
Understanding the evolution of the polar sea ice is not enough to study the effects of the climate change on marine ecosystems in Antarctic seafloors. It is also necessary to determine the intensity of phytoplankton local production during the Antarctic summer, as stated in a new study by a...
93-million-year-old shark would have resembled manta and devil rays. Researchers announced the discovery of a nearly complete fossil of the shark, called Aquilolamna milarcae, that lived during the Cretaceous Period at a time when dinosaurs ruled the land. Its unusual proportions – a fin span of about 6-1/4 feet (1.9 meters)...
In 2017, the first interstellar object from beyond our solar system was discovered via the Pan-STARRS astronomical observatory in Hawaii. It was named 'Oumuamua, meaning "scout" or "messenger" in Hawaiian. The object was like a comet, but with features that were just odd enough to defy classification. Two Arizona...
The fossil in question is that of an oviraptorosaur, a group of bird-like theropod dinosaurs that thrived during the Cretaceous Period, the third and final time period of the Mesozoic Era (commonly known as the ‘Age of Dinosaurs’) that extended from 145 to 66 million years ago. The new...
Media accreditation is now open for NASA’s SpaceX Crew-2 mission to the International Space Station. This is the second crew rotation flight with astronauts on the Crew Dragon spacecraft and the first launch with two international partners as part of the agency’s Commercial Crew Program. The launch, on a Falcon...
