Yellowstone volcano: How ‘major earthquake’ put USGS on alert – ‘Plates grinding!’ | Science | News

The Yellowstone volcano is dubbed a supervolcano due to its capability to inflict global devastation during a supereruption, something that has happened three times in the past – 2.1 million years ago, 1.3 million years ago and 640,000 years ago. Located below the states of Wyoming, Montana and Idaho, the area is constantly monitored by the USGS (United States Geological Survey) for signs that a supereruption is on its way. While most of these incidents are nowhere near the levels needed to trigger an eruption, the 1959 Hebgen Lake earthquake that occurred on August 17,…

Life on Mars: ‘Puzzling’ CO2 and ozone traces fuel Martian methane mystery | Science | News

The methane mystery on Mars is exciting because the gas is known to break down in just 400 years. The detections, therefore, suggest the gas was produced or released in the relative past. In June 2019, NASA scientists behind the Curiosity rover mission detected about 21 parts per billion units by volume (ppbv) of methane – the largest amount of methane ever measured by the mission. However, it was unclear what the source of the methane was and follow-up measurements a week later produced significantly lower results. Paul Mahaffy of…

Space news: Hyades star cluster caught in its ‘death throes’ will soon disappear | Science | News

The Hyades cluster is losing mass at an accelerated rate and has entered its twilight years. Hyades is the closest open cluster to Earth, located only 150 light-years away. For comparison, the galactic centre of the Milky Way is about 26,000 light-years away – 152,844,260,000,000,000 miles. In a paper published on the Cornell University preprint server arXiv.org, astronomers have predicted when the cluster will disappear. The paper has been titled Kinematic modelling of clusters with Gaia: the Death Throes of the Hyades. Dr Semyeong Oh, an astronomer at the University…

Black hole news: NASA shows sheer fury of supermassive black hole | Science | News

NASA’s Hubble telescope snapped an image of the supermassive black hole at the centre of the M87 galaxy, emitting a powerful jet. The black hole is 55 million light years away and has around 6.5billion times the mass of the Sun and a diameter which is 3 million times that of Earth. In the image from NASA, a powerful jet can be seen stemming from the black hole’s core. The jet is made via the black hole’s accretion disk, which is shooting out particles at near light speed. Accretion disks…

Chernobyl fungi could save space travellers as it EATS radiation – study | Science | News

The fungi growing inside the aftermath of the Chernobyl disaster could help protect humans from radiation during space travel. The fungi was discovered in 1991, five years after the disaster, and experts have discovered that it feeds on radiation. The fungi, named Cryptococcus neoformans fungi, contains large amounts of melanin – a pigment found in skin which turns it dark. The copious melanin levels absorb the harmful radiation, turning it into chemical energy, in the same way plants convert carbon dioxide and chlorophyll into oxygen and glucose via photosynthesis. It…

Archaeology MAPPED: Best places in the UK to find buried treasure REVEALED | Science | News

New research by online metals retailer metals4U has revealed the most lucrative areas of the UK to go metal detecting. More than 44,000 archaeological items have been discovered by metal detectors in the past 12 months, meaning 120 pieces of treasure are unearthed every day. Norfolk takes the top spot, with more than 6,500 items discovered since June 2019, including a Bronze Age sword and a Medieval chandelier. And this number is likely to rise, with Brits looking for new outdoor pastimes to enjoy during their summer staycations. Following Norfolk,…

Mars in 4K: NASA Red Planet rover’s surface photos are remastered in STUNNING ultra HD | Science | News

All of the images are publicly available and shared by US-based space agency NASA, including a 1.8 billion pixel mosaic of the Martian surface. This was taken from the Glen Torridon area, consisting of more than 1,000 images from Curiosity taken last year. Mosaics are considered a good way for NASA to increase the available quality of the images beamed-back to Earth by their rovers. Among the panoramic images and ‘sweeping views’ featured in the video are scenes of the Meridiani Planum showing tracks made by Opportunity. Source link

Astronomy news: Never before seen cosmic structures spotted in distant galaxy | Science | News

A distant galaxy has thrown up some unexpected surprises to astronomers, including superbubbles, giant loops and X-shaped magnetic field structures. Astronomers have been observing a spiral galaxy known as NGC 4217, which is 67 million lightyears away, in order to understand more about our Milky Way. Spiral galaxies can have sprawling magnetic fields, but why has always remained a bit of a mystery. However, new research used radio observations to help unravel the enigma. NGC 4217 has several “remarkable” structures which made it the ideal candidate to look at. Most…

Proteus: Engineers create material so tough even an ANGLE GRINDER can’t cut it | Science | News

The non-cuttable material is made from alumina ceramic spheres encased in a cellular aluminium, metallic foam structure Proteus works by turning back the force of a cutting tool on itself. In tests, Proteus could not be cut by angle grinders, drills, or high-pressure water jets. The interlocking vibrational connection created by the ceramic spheres inside the casing resists the cutting disc or drill bit. Source link

Artificial intelligence: AI ‘too dangerous to release’ STUNS experts – ‘Mind blowing’ | Science | News

The artificial intelligence tool Generative Pre-training Transformer (GPT-3) has stunned experts with its unerring ability to design websites, prescribe medication and even answer questions. GPT-3 is the third generation of the machine learning model, where computers can automatically learn from their experiences without having to be programmed. The AI’s predecessor GPT-2, made headlines after being dubbed “too dangerous to release” due to its ability to create text apparently indistinguishable from that written by human beings. While GPT-2 had 1.5 billion parameters which could be set, the AI’s successor has 175…
