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.....»»
High-mass stars are formed not from dust disk but from debris
A Dutch-led team of astronomers has discovered that high-mass stars are formed differently from their smaller siblings. Whereas small stars are often surrounded by an orderly disk of dust and matter, the supply of matter to large stars is a chaotic m.....»»
FAST detects 3D spin-velocity alignment in a pulsar
Pulsars—another name for fast-spinning neutron stars—originate from the imploded cores of massive dying stars through supernova explosion......»»
Intel Core i7-11370H Review: Quad-Cores Aren"t Enough in 2021
The Core i7-11370H is part of the Tiger Lake H35 line-up that bridges the gap between the UP3 series for ultraportables, and the 45W H-series chips used for work and gaming machines. Unfortunately, it fails at it......»»
A violent delidding reveals that Intel"s Sapphire Rapids CPUs could have up to 80 cores
Eighty cores is twice the amount you can currently purchase from Intel for up to $8,099, though it’s only a third more than what AMD could sell you for $7,890. But Intel’s flashiest Xeons and AMD’s shiniest Epycs are more similar than you'd ima.....»»
Ryzen rumors: Zen 5 to use Alder Lake-style hybrid design, Zen 3+ canceled due to chip shortage
Intel's Alder Lake chips, set to debut in the second half of this year, will bring the combination of larger high-performance cores and smaller high-efficiency cores to desktop x86 PCs. 2022's Raptor Lake, which also uses the LGA 1700 socket, will fe.....»»
A superluminous supernova from a massive progenitor star
Stars greater than about eight solar-masses end their lives spectacularly as supernovae. These single-star supernovae are called core collapse supernovae because their dense cores, composed primarily of iron at this late stage of their lives, are no.....»»
Surprise twist suggests stars grow competitively
A survey of star formation activity in the Orion Nebula Cluster found similar mass distributions for newborn stars and dense gas cores, which may evolve into stars. Counterintuitively, this means that the amount of gas a core accretes as it develops,.....»»
Machine-learning methods lead to discovery of rare "quadruply imaged quasars"
With the help of machine-learning techniques, a team of astronomers has discovered a dozen quasars that have been warped by a naturally occurring cosmic "lens" and split into four similar images. Quasars are extremely luminous cores of distant galaxi.....»»
Intel’s Ice Lake Xeon comes out swinging at AMD’s Epyc Milan
Chipzilla's new server processors bring more cores, more RAM, more features. Enlarge / Thirty-six individual models of Ice Lake Xeon Scalable processor launch today, with immediate retail availability expected from major system vendors, includin.....»»
Some Dead Stars May Harbor Enough Uranium To Set Off a Thermonuclear Bomb
sciencehabit shares a report from Science Magazine: A thermonuclear bomb might be ticking deep in the cores of some dead stars. A new theoretical study traces out how certain stellar corpses known as white dwarfs could accumulate a critical mass of u.....»»
Not so fast, supernova: Highest-energy cosmic rays detected in star clusters
For decades, researchers assumed the cosmic rays that regularly bombard Earth from the far reaches of the galaxy are born when stars go supernova—when they grow too massive to support the fusion occurring at their cores and explode......»»
A 64-core Mac Pro priced at $19,000+ rumored to arrive next year
The speculation comes from @LeaksApplePro, who claims at least three Mac Pro configurations will arrive next year featuring Arm-based SoCs that mix performance and efficiency cores, just like the M1. The rumored flagship comes with a monstrous 64 CPU.....»»
RTX 3060 prices suggest it will be 50% more expensive than the MSRP
The RTX 3060 is supposed to offer fantastic value for money, with 3,548 Cuda cores and 12GB of GDDR6 for just $329. But with no Founders Edition, there was little expectation that third-party manufacturers would stick with that price......»»
Cold dust cores in the central zone of the Milky Way
The Milky Way's central molecular zone (CMZ) spans the innermost 1600 light-years of the galaxy (for comparison, the Sun is 26,600 light-years away from the galactic center) and includes a vast complex of molecular clouds containing about sixty milli.....»»

Astronomers uncover mysterious origins of "super-Earths"
Mini-Neptunes and super-Earths up to four times the size of our own are the most common exoplanets orbiting stars beyond our solar system. Until now, super-Earths were thought to be the rocky cores of mini-Neptunes whose gassy atmospheres were blown.....»»
RapidSOS raises $85M for a big data platform aimed at emergency responders
Emergency response services have been one of the unsung heroes of the last chaotic year, providing essential and urgent medical and other assistance during a period that has faced not just the usual run of natural and man-made disasters, but a global.....»»
Decoding the age of the ice at Mars" north pole
Mars' north pole contains a large ice cap made up of many layers of frozen water. Like ice cores on Earth, those layers offer a tantalizing record of climate on Mars over the past several million years. The first step in decoding that climate record.....»»
Galaxy-Size Gravitational-Wave Detector Hints At Exotic Physics
The fabric of spacetime may be frothing with gigantic gravitational waves, and the possibility has sent physicists into a tizzy. A potential signal seen in the light from dead stellar cores known as pulsars has driven a flurry of theoretical papers s.....»»
Image: Hubble spots an interstellar interaction
The life of a planetary nebula is often chaotic, from the death of its parent star to the scattering of its contents far out into space. Captured here by the NASA/ESA Hubble Space Telescope, ESO 455-10 is one such planetary nebula, located in the con.....»»
