Squid Galaxy Gets in on the Neutrino Game
Astronomers have connected dozens of neutrinos detected by the IceCube Observatory to a nearby galaxy, M77, aka the Squid Galaxy.
Giant Black Holes Make Tiny, Ghost-like Particles
Blazars, the gas-guzzling black holes at the center of galaxies, could make most of the tiny particles known as neutrinos we catch on Earth.
Astronomers Announce Priorities for Next Decade
The National Academy of Science detailed the direction for astronomy and astrophysics today for the coming decade.
Star-shredding Black Hole Makes Ghostlike Particle
A single high-energy neutrino may shed light on a star being swallowed by a supermassive black hole some 690 million light-years away.
IceCube Neutrino Offers New Eyes on the Cosmos
A combination of neutrino detection and observations across the full spectrum of light has pinpointed a cosmic accelerator for the first time, revitalizing multi-messenger astronomy.
Search for Fourth Neutrino Goes Cold
The Antarctic observatory known as IceCube has ruled out the existence of a fourth type of neutrino particle — and one-time dark matter contender — known as the light sterile neutrino.
Where Big Bird Neutrino May Come From
Scientists might have found the source of an incredibly energetic particle that bored into the Antarctic ice sheet.
South Pole Science
A behind-the-scenes look at the construction of the IceCube Neutrino Observatory in Antarctica, plus more information about science done at the South Pole. (This blog is an online companion to our January 2014 feature article on IceCube.)
Cosmic Ray Origin Still Mysterious
Observations out of Antarctica support the idea that the most energetic of the superspeedy space particles raining down on Earth are not from gamma-ray bursts. The new result prolongs a long-standing mystery in astrophysics.
