The remnants of former Tropical Storm Beryl are being battered by upper level winds, and that's fragmenting them even more. NASA's Aqua satellite passed over the northwestern Atlantic Ocean and found some of those scattered thunderstorms were strong.
For the first time, the source object which produced an ultra-high energy neutrino has been identified. This discovery was made possible by collaboration between the IceCube experiment in Antarctica and telescopes worldwide, including NAOJ's Subaru Telescope in Hawai'i.
An international team of scientists that includes UC Riverside physicist Hai-Bo Yu has imposed conditions on how dark matter may interact with ordinary matter. In the search for direct detection of dark matter, the experimental focus has been on WIMPs, or weakly interacting massive particles, the hypothetical particles thought to make up dark matter. But the research team invokes a different theory to challenge the WIMP paradigm: the self-interacting dark matter model, or SIDM.
In a paper published this week in the journal Science, scientists have, for the first time, provided evidence for a known blazar, designated TXS 0506+056, as a source of high-energy neutrinos. At 8:54 p.m. on Sept. 22, 2017, the National Science Foundation-supported IceCube neutrino observatory at the South Pole detected a high energy neutrino from a direction near the constellation Orion. Just 44 seconds later an alert went out to the entire astronomical community.
An MIT study finds black holes and neutron stars are key to measuring our expanding universe.
Using the power and synergy of two space telescopes, astronomers have made the most precise measurement to date of the universe's expansion rate.
Former Tropical Storm Beryl doesn't seem to want to dissipate into hurricane history. Visible data from NASA's Terra satellite captured the the remnants of Beryl lingering north of the Bahamas.
As Tropical Storm Chris was strengthening into a short-lived hurricane, the Global Precipitation Measurement mission or GPM core satellite investigated the storm's rainfall and cloud heights. By July 12, Chris weakened to a tropical storm and was passing by Nova Scotia, Canada.
The VERITAS array has confirmed the detection of high-energy gamma rays from the vicinity of a supermassive black hole located in a distant galaxy, TXS 0506+056. While these detections are relatively common for VERITAS, this black hole is potentially the first known astrophysical source of high-energy cosmic neutrinos, a type of ghostly subatomic particle that can be made at astrophysical sources of ultra-high energy cosmic rays.
Researchers help to resolve a more than century-old riddle about what sends subatomic particles such as neutrinos and cosmic rays speeding through the universe.
