Giant neutrino telescope to open window to ultra-high-energy universe. The long-sought, elusive ultra-high-energy neutrinos, ghost-like particles that travel cosmological-scale distances, are key to understanding the…
An international team of scientists has announced a breakthrough in its quest to measure the mass of the neutrino, one of the most abundant, yet…
Major steps forward in understanding neutrino properties. In the quest to prove that matter can be produced without antimatter, the GERDA experiment at the Gran…
Joseph Formaggio explains the discovery that the ghostly particle must be no more than 1 electronvolt, half as massive as previously thought. An international team…
The VERITAS array has confirmed the detection of gamma rays from the vicinity of a supermassive black hole. While these detections are relatively common for…
For the first time ever, scientists using NASA’s Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. This…
Astronomers and physicists around the world, including in Hawaii, have begun to unravel a long-standing cosmic mystery. Using a vast array of telescopes in space…
Theoretical physicists calculate the origin of a high-energy particle track captured by the IceCube Neutrino Observatory It was just eight years ago that the IceCube…
New data could shed light on why the universe has more matter than antimatter. This week, an international team of physicists, including researchers at MIT,…
If equal amounts of matter and antimatter had formed in the Big Bang more than 13 billion years ago, one would have annihilated the other…
New model connects the origins of very high-energy neutrinos, ultrahigh-energy cosmic rays, and high-energy gamma rays with black-hole jets embedded in their environments. One of…
Using elaborate computer simulations, researchers show how radioactive elements in gaseous supernova remnant Cassiopeia A can provide glimpses into the explosion of massive stars. Stars…
Nearly 10 billion years ago, the black hole at the center of a galaxy known as PKS B1424-418 produced a powerful outburst. Light from this…
The IceCube Collaboration and DM-Ice have announced new observations on cosmic neutrinos and the nature of dark matter. Yale University physicists are part of two…
Using data from the IceCube Neutrino Observatory, scientists have confirmed the existence of astrophysical neutrinos from our galaxy as well as cosmic neutrinos from sources…
A new tabletop particle detector is able to identify single electrons in a radioactive gas, a big step toward measuring the mass of a neutrino….
An international team of scientists has published an extensive report on the future of astrophysical neutrino measurements, discussing how facilities that measure the microwave background…
Using three NASA satellites, astronomers have revealed the first evidence that the Milky Way’s supermassive black hole (Sagittarius A*) may be producing neutrinos. The giant…
