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.....»»
Astronomers discover irregularities in the cores of red giants
Red giants are dying stars, in advanced stages of stellar evolution, which have depleted the hydrogen in their cores. In a study published today in Nature Communications, a team of astronomers mainly from Instituto de Astrofísica e Ciências do Espa.....»»
NASA"s Perseverance rover collects two samples of Martian regolith
NASA's Perseverance rover snagged two new samples from the Martian surface on Dec. 2 and 6. But unlike the 15 rock cores collected to date, these newest samples came from a pile of wind-blown sand and dust similar to but smaller than a dune. Now cont.....»»

Perturbing the Bernoulli shift map in binary systems
Is it possible for a deterministic system to be unpredictable? Although counter-intuitive, the answer is yes. Such systems are called "chaotic systems," which are characterized by sensitive dependence on initial conditions and long-term unpredictabil.....»»
Volcanic activity and low ocean oxygen events linked to climate warming and rapid ice melt during last ice age
A chemical analysis of sediment cores from the North Pacific Ocean show a consistent pairing of volcanic ash and hypoxia, a low ocean oxygen condition spanning thousands of years, during times of rapid climate warming at the end of the last ice age,.....»»
Nvidia RTX 4080 prices look a lot better in the US
Nvidia was originally going to launch two versions of the RTX 4080, a 16GB model and a cut-down 12GB card. But the backlash over releasing something with 4GB less VRAM, 25% fewer CUDA cores, and a narrower memory bus than the RTX 4080 16GB while pric.....»»
Geekbench was tricked: the Ryzen 7 7800X doesn"t exist
Nope. Chips and Cheese has come clean. They fooled Geekbench with a phony name by spoofing the CPUID on what was actually a Ryzen 9 7950X system. They also disabled six cores and reduced the precision boost overdrive clock by 350 MHz to make it look.....»»
