Astronomers have used NASA’s Chandra X-ray Observatory to record material blasting away from the site of an exploded star at speeds faster than 20 million miles per hour. This is about 25,000 times faster than the speed of sound on Earth.
Kepler’s supernova remnant is the debris from a detonated star that is located about 20,000 light years away from Earth in our Milky Way galaxy. In 1604 early astronomers, including Johannes Kepler who became the object’s namesake, saw the supernova explosion that destroyed the star.
We now know that Kepler’s supernova remnant is the aftermath of a so-called Type Ia supernova, where a small dense star, known as a white dwarf, exceeds a critical mass limit after interacting with a companion star and undergoes a thermonuclear explosion that shatters the white dwarf and launches its remains outward.
NASA’s Mars rovers have been one of the great scientific and space successes of the past two decades.
Four generations of rovers have traversed the red planet gathering scientific data, sending back evocative photographs, and surviving incredibly harsh conditions—all using on-board computers less powerful than an iPhone 1. The latest rover, Perseverance, was launched on July 30, 2020, and engineers are already dreaming of a future generation of rovers.
While a major achievement, these missions have only scratched the surface (literally and figuratively) of the planet and its geology, geography, and atmosphere.
The Raptor engine, designed to power the ship that will send humans to Mars and beyond, has been racking up impressive test results.
Aug. 18 (UPI) — New research suggests harmful cosmic rays from a nearby supernova might have caused the extinction events that form the boundary between the Devonian-Carboniferous periods.
Around 360 million years ago, a lengthy period of biodiversity declines culminated in a series of extinction events that saw 19 percent of all families and 50 percent of all genera disappear.
Scientists have previously unearthed a diversity of Late Devonian plant spores that show evidence of being burnt by ultraviolet light, signs of a prolonged ozone-depletion event.
SpaceX, the Elon Musk-led company that recently became the first business in history to send astronauts into Earth’s orbit, is parlaying its successes into big money.
Nearly three-quarters of older adults with dementia have filled prescriptions for medicines that act on their brain and nervous system, but aren’t designed for dementia, a new study shows.
That’s despite the special risks that such drugs carry for older adults—and the lack of evidence that they actually ease the dementia-related behavior problems that often prompt a doctor’s prescription in patients with Alzheimer’s disease and related disorders. In fact, some of the drugs have been linked to worse cognitive symptoms in old adults.
The study looks at several classes of psychoactive drugs, including ones that the federal government has actively encouraged nursing homes to limit using in residents with dementia. The new study suggests a need to reduce prescribing to people living at home with dementia, too.
