SUNSET: 
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.
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.
Simulation Sees Supernova Innards
A new computer simulation provides a brief glimpse at what makes stellar bombs tick.
The Kavli Foundation Q&A: What Has Planck Taught Us About the Early Universe?
Scientist George Efstathiou weighs in on the latest results from the Planck satellite and what they say about cosmic inflation, the first stars, and more.
Mysterious X-rays Might Hint at Dark Matter
Astronomers have discovered a spike of X-ray emission in galaxy clusters — “ordinary” interpretations don’t hold up, so some are turning to dark matter for answers.
Closing In on Neutrino Properties
The heart of the Sudbury Neutrino Observatory is an acrylic sphere filled with heavy water and surrounded by photomultiplier tubes. These detect flashes of light produced when neutrinos interact with the water. This fisheye view was taken from beneath the sphere before the bottom panel of detectors was installed.Courtesy Ernest…
