‘God of chaos’: Milky Way star on the brink of massive gamma-ray supernova explosion
Posted by Michael Lance in category: cosmology
A star 8,000 light years from Earth is on the verge of a huge supernova explosion, which could produce the Milky Way’s first gamma-ray explosion, a dangerous and extremely energetic event.
Australian scientists at the University of Sydney discovered the rare ‘God of chaos’ star, which they say could produce the Milky Way’s first known gamma-ray burst, a lethal combination of dust and gas mixed with wind as fast as 12 million km/ph, which is one of the most extreme energetic events after the Big Bang.

What do sand, glass ⌛ and this technicolor remnant of a supernova 💥 have in common?
Posted by Michael Lance in categories: cosmology, materials
They all contain silica, a mineral that’s widespread on Earth and in space.
Using NASA’s Spitzer Space Telescope, researchers found that the material is produced by the massive explosions of stars. Details: https://go.nasa.gov/2r6Zq7P

Scientists find possible new species in Caribbean waters
Posted by Genevieve Klien in category: futurism
SAN JUAN, Puerto Rico (AP) — U.S. scientists have wrapped up a 22-day mission exploring waters around Puerto Rico and the U.S. Virgin Islands with the deepest dives ever recorded in the region.
They found a rare shark embryo, 2-meter (7 feet) high corals and sponges with sharp edges, among hundreds of other things.
Daniel Wagner was the expedition coordinator with the U.S. National Oceanic and Atmospheric Administration. He told The Associated Press on Wednesday that scientists collected 89 samples overall and will now start to analyze them. He said scientists believe they may have found several new species, although it will take years to confirm.

The microscope revolution that’s sweeping through materials science
Posted by Genevieve Klien in categories: particle physics, science
Scientists can’t study what they can’t measure — as David Muller knows only too well. An applied physicist, Muller has been grappling for years with the limitations of the best imaging tools available as he seeks to probe materials at the atomic scale.
One particularly vexing quarry has been ultra-thin layers of the material molybdenum disulfide, which show promise for building thin, flexible electronics. Muller and his colleagues at Cornell University in Ithaca, New York, have spent years peering at MoS2 samples under an electron microscope to discern their atomic structures. The problem was seeing the sulfur atoms clearly, Muller says. Raising the energy of the electron beam would sharpen the image, but knock atoms out of the MoS2 sheet in the process. Anyone hoping to say something definitive about defects in the structure would have to guess. “It would take a lot of courage, and maybe half the time, you’d be right,” he says.
This July, Muller’s team reported a breakthrough. Using an ultra-sensitive detector that the researchers had created and a special method for reconstructing the data, they resolved features in MoS2 down to 0.39 angstroms, two and a half times better than a conventional electron microscope would achieve. (1 Å is one-tenth of a nanometre, and a common measure of atomic bond lengths.) At once, formerly fuzzy sulfur atoms now showed up clearly — and so did ‘holes’ where they were absent. Ordinary electron microscopy is “like flying propeller planes”, Muller says. “Now we have a jet.”
