Astronomers solve the case of missing carbon monoxide in protoplanetary disks
Astronomers frequently observe carbon monoxide in planetary nurseries. The compound is ultra-bright and extremely common in protoplanetary disks—regions of dust and gas where planets form around young stars—making it ...

Explosive origins of 'secondary' ice—and snow
Where does snow come from? This may seem like a simple question to ponder as half the planet emerges from a season of watching whimsical flakes fall from the sky—and shoveling them from driveways. But a new study on how ...

IceCube detection of a high-energy particle proves 60-year-old theory
On December 6, 2016, a high-energy particle called an electron antineutrino hurtled to Earth from outer space at close to the speed of light carrying 6.3 petaelectronvolts (PeV) of energy. Deep inside the ice sheet at the ...

Best of Last Week – Setting a quantum speed limit, slowing the speed of light and turning back the aging clock
(Phys.org)—It was a very busy week for physics research. A team of scientists has set a quantum speed limit—the group at the University of California found a way to prove a fundamental relationship between energy and ...
Soot suspect in puzzling mid-1800s Alps glacier retreat
Scientists have uncovered strong evidence that soot, or black carbon, sent into the air by a rapidly industrializing Europe, likely caused the abrupt retreat of mountain glaciers in the European Alps.

IceCube Neutrino Observatory reports first evidence for extraterrestrial high-energy neutrinos
(Phys.org) —A massive telescope in the Antarctic ice reports the detection of 28 extremely high-energy neutrinos that might have their origin in cosmic sources. Two of these reached energies greater than 1 petaelectronvolt ...

Where do the highest-energy cosmic rays come from? Not from gamma-ray bursts, says IceCube study
The IceCube neutrino telescope encompasses a cubic kilometer of clear Antarctic ice under the South Pole, a volume seeded with an array of 5,160 sensitive digital optical modules (DOMs) that precisely track the direction ...

Atmospheric lead causes clouds to form more easily, could change pattern of rain and snow
(PhysOrg.com) -- By sampling clouds -- and making their own -- researchers have shown for the first time a direct relation between lead in the sky and the formation of ice crystals that foster clouds. The results suggest ...
