The galactic sources of nine extremely high-energy gamma rays have been identified by scientists from Penn State and members of the High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory. All of the sources generate gamma rays with powers more than 56 trillion…
Researchers have discovered signals due to slow slip events with huge amounts of slip along the Nankai Trough subduction zone, southeast of Japan. The findings shed light on the marine sedimentary environment and plate tectonics of Nankai Trough and may help in…
Some scientists theorize that Jupiter acts like a giant space shield– due to its tremendous mass, it sucks in or deflects dangerous space objects. However, studies led by American planetary physicist Kevin Grazier demonstrate that the planet is actually a threat…
A newly published research suggests the crater left behind by the biggest asteroid to ever hit Earth has been found. Traces of the gigantic impact of the meteorite, which crashed on the planet approximately 790 000 years ago, have been observed across around 20% of…
Scientists were able to find the first active fault zone yet on Mars after NASA's InSight mission spacecraft detected marsquakes, with two standing out loud and clear. These events registered between M3 and 4– both were from an area called Cerberus Fossae– a…
A new underwater volcano formed near the island of Mayotte in the Indian Ocean in 2018, which was confirmed in May 2019. Now, an international team of scientists is unraveling the dramatic events that led to its creation. It is the deepest and largest magma…
Researchers found that quasiparticles in quantum systems could be effectively immortal, as detailed in their study published in Nature Physics. These quantum particles, however, still decay but once they do, they are able to rebuild themselves back into existence–…
NASA intern Jennifer Briggs, a physics student at Pepperdine University in California, discovered a new type of aurora in three-year-old footage of the Arctic Sky. Scientists were able to correlate the never-before-seen aurora to a sudden compression in Earth's…
Betelgeuse, one of the brightest stars in the night sky, has been dramatically dimming recently, indicating that it's about to enter its last phase of life before finally exploding into a supernova. Some scientists believe that Betelgeuse may be ready to go…
Scientists have suspected for many years that decades-long droughts occurred in North and South America simultaneously during the Middle Ages. By studying ancient tree rings, pieces of evidence have been discovered that tandem droughts are common over the past 1 200…
