RIVERSIDE, Calif. -- An international team of scientists that includes University of California, Riverside, physicist Hai-Bo Yu has imposed conditions on how dark matter may interact with ordinary matter -- constraints that can help identify the elusive dark matter particle and detect it on Earth. Dark matter -- nonluminous material in space --…

Hawaii telescopes help unravel long-standing cosmic mystery

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 and on Earth, they have identified a source of cosmic rays--highly energetic particles that continuously rain down on Earth from space. In a paper published this week in the journal Science, scientists have, for the first time, provided evidence for…

MAGIC telescopes trace origin of a rare cosmic neutrino

For the first time, astrophysicists have localized the source of a high energy cosmic neutrino originating outside the Milky Way. It is highly likely that the neutrino comes from a blazar in the Orion constellation. Scientists reached this interesting finding by combining a neutrino signal from IceCube with measurements from other instruments, e.g. the Fermi-LAT and MAGIC telescopes. This multi-messenger observation provided a clue to…

University of Alabama professors help in discovery of potential cosmic ray...

TUSCALOOSA, Ala. - Three professors at The University of Alabama are part of an international team of scientists who found evidence of the source of tiny cosmic particles, known as neutrinos, a discovery that opens the door to using these particles to observe the universe. "We're beginning to do astronomy using means other than light, combining electromagnetic (light) observations with other measurements in what we…

Blazar accelerates cosmic neutrinos to highest energies

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from…

University of Leicester scientists involved in discovery of origins of ‘ghost...

Scientists from the University of Leicester have played a key role in a momentous discovery about the origins of 'ghostly' particles from the distance universe that bombard Earth from billions of light years away. The Leicester team from the Department of Physics & Astronomy are part of a global network of researchers that have helped to resolve a more than century-old riddle about what sends…

Students from Missouri, Mississippi to Call Space Station

Students in St. Louis and southern Mississippi will get to ask questions of NASA astronauts on the International Space Station during two events next week as part of NASA’s Year of Education on Station.

Could gravitational waves reveal how fast our universe is expanding?

CAMBRIDGE, Mass. -- Since it first exploded into existence 13.8 billion years ago, the universe has been expanding, dragging along with it hundreds of billions of galaxies and stars, much like raisins in a rapidly rising dough. Astronomers have pointed telescopes to certain stars and other cosmic sources to measure their distance from Earth and how fast they are moving away from us -- two…

New era of space research launched by IceCube Observatory and global...

The first-ever identification of a deep-space source of the super-energetic subatomic particles known as high-energy neutrinos is being heralded today as inaugurating a new era of space research. Detection of a single such neutrino deep beneath the Antarctic ice cap last fall sent a global team of astronomers racing to track down its cosmic origins, ultimately leading them to a flaring supermassive black hole 3.7…

Hubble and Gaia team up to fuel cosmic conundrum
