Astronomers Catch a Superflare From a Puny Star

Astronomers recently spied a massive flare on a tiny diminutive star, a powerful, radiation spewing event that you wouldn't want to witness up close. The post Astronomers Catch a Superflare From a Puny Star appeared first on Universe Today.

Researchers Measure Atom With Half-Life of 18 Sextillion Years

A detector designed to hunt for dark matter has succeeded in detecting one of the rarest particle interactions in the universe. "According to a new study published today in the journal Nature, the team of more than 100 researchers measured, for the first time ever, the decay of a xenon-124 atom into a tellurium 124 atom through an extremely rare process called two-neutrino double electron capture," reports Live Science. "This type of radioactive decay occurs when an atom's nucleus absorbs two electrons from its outer electron shell simultaneously, thereby releasing a double dose of the ghostly particles called neutrinos." From the report: By measuring this unique decay in a lab for the first time, the researchers were able to prove precisely how rare the reaction is and how long it takes xenon-124 to decay. The half-life of xenon-124 -- that is, the average time required for a group of xenon-124 atoms to diminish by half -- is about 18 sextillion years (1.8 x 10^22 years), roughly 1 trillion times the current age of the universe. This marks the single longest half-life ever directly measured in a lab. Only one nuclear-decay process in the universe has a longer half-life: the decay of tellurium-128, which has a half-life more than 100 times longer than that of xenon-124. But this vanishingly rare event has only been calculated on paper. Read more of this story at Slashdot.

Scientists Have Developed a Brain Implant That Can Read People's Minds

An anonymous reader quotes a report from the BBC: The team at the University of California, San Francisco says the technology is "exhilarating." They add that their findings, published in the journal Nature, could help people when disease robs them of their ability to talk. The mind-reading technology works in two stages. First an electrode is implanted in the brain to pick up the electrical signals that maneuver the lips, tongue, voice box and jaw. Then powerful computing is used to simulate how the movements in the mouth and throat would form different sounds. This results in synthesized speech coming out of a "virtual vocal tract." "The system is better with prolonged sounds like the 'sh' in ship than with abrupt sounds such as the 'buh' sound in 'books,'" the report adds. "In experiments with five people, who read hundreds of sentences, listeners were able to discern what was being spoken up to 70% of the time when they were given a list of words to choose from."

Astronomers Think a Meteor Came from Outside the Solar System

When ‘Oumuamua was first detected on October 19th, 2017, astronomers were understandably confused about the nature of this strange object. Initially thought to be an interstellar comet, it was then designated as an interstellar asteroid. But when it picked up velocity as it departed our Solar System (a very comet-like thing to do), scientists could … Continue reading "Astronomers Think a Meteor Came from Outside the Solar System" The post Astronomers Think a Meteor Came from Outside the Solar System appeared first on Universe Today.

First 'Marsquake' Detected on Red Planet

There are earthquakes and moonquakes, and now a NASA spacecraft has detected what's believed to be a "marsquake" on the Red Planet. From a report: The spacecraft picked up the faint trembling of Mars's surface on 6 April, 128 days after landing on the planet last November. The quake is the first to be detected on a planetary body other than Earth or Moon. The shaking was relatively weak, the French space agency CNES said on 23 April. The seismic energy it produced was similar to that of the moonquakes that Apollo astronauts measured in the late 1960s and early 1970s. "We thought Mars was probably going to be somewhere between Earth and the Moon" in terms of seismic activity, says Renee Weber, a planetary scientist at NASA's Marshall Space Flight Center in Huntsville, Alabama. "It's still very early in the mission, but it's looking a bit more Moon-like than Earth-like," she says. It's not yet clear whether the shaking originated within Mars or was caused by a meteorite crashing into the planet's surface. Read more of this story at Slashdot.
