The chaotic cores of Perseus protostars
The formation of a star has a simple tale. A region of interstellar gas collapses under its own weight, eventually forming a dense protostar surrounded by a disk of gas and dust. The protostar and the disk rotate in the same plane, and often jets of.....»»
Alienware vBIOS abducts CUDA cores from the RTX 3070

Jets from massive protostars might be very different from lower-mass systems
Astronomers studying the fast-moving jet of material ejected by a still-forming, massive young star found a major difference between that jet and those ejected by less-massive young stars. The scientists made the discovery by using the U.S. National.....»»
White dwarf stars" debris disk formation delayed
White dwarfs, the glowing cores of dead stars, often host disks of dusty debris. However, these debris disks only appear 10 to 20 millions of years following the star's violent Red Giant phase. A new paper by Planetary Science Institute Research Sci.....»»
Dead zones formed repeatedly in North Pacific during warm climates, study finds
An analysis of sediment cores from the Bering Sea has revealed a recurring relationship between warmer climates and abrupt episodes of low-oxygen "dead zones" in the subarctic North Pacific Ocean over the past 1.2 million years......»»
Taking Lyft’s new e-bike for a spin
The bike had none of the usual signage when I took it for a spin around the chaotic and construction-filled streets of Manhattan. It very much looked like a prototype, with visible soldering on the joints and a not-quite-complete AV system. But it ha.....»»
