Scientists may have discovered when and how the high-energy particles that bombard the Earth and other objects emerge from violent environments like sun atmosphere. These high-energy particles pose a threat to sensitive satellite technology And astronauts, and can even affect aircraft flying over the North Pole. Although researchers have been studying these particles for decades, … Read more

Credit: Jingchuan Yu Fast Radio Bursts – A deep and puzzling puzzle An international team of scientists reveals the evolving, magnetized environment and location of a surprising source of fast radio bursts in deep space – observations that challenge current understanding. … Read more
A man sits at his work station inside the mission operations center of the Dual Asteroid Redirection Test (DART) spacecraft, which is rapidly approaching its target. I bet dinosaurs wish they’d thought about that. On Monday, NASA will attempt a feat humanity has never accomplished before: deliberately smashing a spacecraft into an asteroid to twist … Read more

Credit: Satoshi Kaya / Flickr Scientists who have delved deeper into an undersea earthquake fault than ever before have found that tectonic stress in Japan’s Nankai subduction zone is lower than expected, according to … Read more
A theoretical physicist who had never had a regular job won the most lucrative prize in science for his pioneering contributions to the field of quantum computing. David Deutsch, who belongs to Oxford universitythe $3 million (about £2.65 million) breakthrough prize in fundamental physics along with three other researchers laid the foundations for the broader … Read more
Zoom / There is a long tradition of empirical testing of the weak equivalence principle – the basis of Albert Einstein’s general theory of relativity. ONERA One of the most counter-intuitive concepts in physics is that all objects fall at the same rate, regardless of mass, aka Equivalence principle. This was most memorably illustrated in … Read more

Scientists from Ames National Laboratory and Iowa State University have developed a … Read more
CERN physicist Jimmy Boyd enters a tunnel near the ATLAS detector, an experiment at the world’s largest particle accelerator. From there, it turns into an underground space called TI12. “This is a very special tunnel,” Boyd says, “because that’s where the old transmission line of the Large Electron-Positron Collider used to be, before the Large … Read more
Experimental setup. Scheme of experimental setup for each shot: (1) selection of a 500 kV energy proton beam from the initial broadband TNSA spectrum generated by the main beam, (2) generation of a WDM sample by the heater beam, (3) downshift measurement of the proton energy spectrum of the selected beam after Passing through the … Read more
