Using NASA’s Fermi and Swift spacecraft, astronomers have investigated SGR J1935+2154, the most recurring transient magnetar known to date. The new research sheds more light on the burst properties of this object. The study is detailed in a paper published March 23 on the arXiv pre-print repository.

Quasar tsunamis rip across galaxies
Astronomers using the Hubble Telescope found that the region around a quasar’s black hole pushes out material at a few percent the speed of light. These quasar tsunamis wreak havoc on the galaxies in which the quasars live. Source: https://earthsky.org/space/quasar-tsunamis-rip-across-galaxies…
We’ve figured out why bubbles make a ‘pop’ sound when they burst
A number of difference forces are involved in producing sound when a bubble pops, and the exact noise depends on the chemical properties of the soap film Source: https://www.newscientist.com/article/2238125-weve-figured-out-why-bubbles-make-a-pop-sound-when-they-burst/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
SpaceX Starship SN-1 Fails Pressure Test and Explodes
SpaceX envisions Starship as a 387-foot-tall (118 meters) spacecraft/booster that can carry up to 100 people to Mars. Pig Hogger (Slashdot reader #10,379) tipped us off to this progress report from Space.com:
SpaceX’s new Starship prototype appeared to burst during a pressure test late Friday (Feb. 28), rupturing under the glare of flood lights and mist at the company’s south Texas facility….

Chip Industry Had Worst Sales Year Since Dot-Com Bubble Burst
The semiconductor industry last year suffered its worst annual slump in almost two decades, hurt by a trade war between the largest chip producer, the U.S., and the largest consumer, China. Bloomberg reports: Revenue fell 12% to $412 billion in 2019, the Semiconductor Industry Association said Monday in a statement. That’s the biggest drop since 2001, when industry sales slumped 32%…
Astronomers watch star swallow up matter, emit heatwave blast, in rare event
Astronomers observe a rare event, as a star engulfs matter and emits a heatwave blast, something called an accretion burst event. Source: https://www.livescience.com/rare-accretion-star-burst-observed.html
