Astronomers say a new type of stellar explosion on distant dead stars — called ‘micronova’ — could be plentiful in our universe
Posted by Genevieve Klien in category: space travel
Using NASA satellite data, researchers observed a new class of stellar explosion, which is similar to novas, but localized and short-lived.

NASA invents ‘revolutionary’ material 1,000 times better than state-of-the art spaceship alloys
Posted by Genevieve Klien in categories: materials, space travel
NASA scientists have invented a new metal alloy that is 1,000 times more durable than current state-of-the-art materials used in aviation and space exploration.
The US space agency believes that Alloy GRX-810 could revolutionise space travel, as it can withstand far harsher conditions than existing materials used within rocket engines.
The material has twice the strength, three-and-a-half times the flexibility and more than 1,000 times the durability under stress at high temperatures.

Alan DeRossettPutin propaganda is dividing opinions on Elon Musk for helping Ukraine and standing up to the Fossil fuel industry.
Walter LynsdaleI’m all for people making billions through technical advancement (teslas, space X rockets, the dojo chip are all pretty cool), but he comes out with a fair amount of double speak:
“people aren’t having enough babies” vs “we can make a humanoid robot”… See more.

Demand for Low-End Laptop CPUs Is Tanking

“Some pullback was expected, but the return to pre-COVID volumes was instantaneous rather than gradual,” he added. Other research firms including Canalys also report demand for Chromebooks has taken a sharp dive in recent months.
McCarron added: “Due to the decline in low-cost entry level shipments, the market average CPU selling price increased the most on-quarter in 23 years.” The average selling price is now at $168, up from $151, according to Mercury Research’s stats.
