The idea was so far-fetched it seemed like science fiction: create an observatory out of a one cubic kilometer block of ice in Antarctica to track ghostly particles called neutrinos that pass through the Earth. But speaking to Benedickt Riedel, global computing manager at the IceCube Neutrino Observatory, it makes perfect sense.
Constructing a comparable observatory anywhere else would be astronomically expensive, Riedel explained. Antarctica ice is a great optical material and allows us to sense neutrinos as nowhere else. ....

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 South Pole, it smashed into an electron and produced a particle that quickly decayed into a shower of secondary particles. The interaction was captured by a massive telescope buried in the Antarctic glacier, the IceCube Neutrino Observatory. ....

Discovery of potential cosmic-ray accelerator in the galaxy opens window for PeV cosmic rays origin

The Tibet ASgamma experiment, a China-Japan joint research project, has discovered gamma rays beyond 100 TeV (tera electron volts) from G106.3+2.7, a supernova remnant (SNR) 2600 lightyears from Earth.
These gamma rays are of the highest energy ever observed from SNRs, and are probably produced in collisions between cosmic rays (protons) accelerated in G106.3+2.7 and a nearby molecular cloud.
SNR G106.3+2.7 is thus the first candidate object with sufficient evidence in the Milky Way that can accelerate cosmic rays (protons) up to 1 PeV (peta electron volts), said HUANG Jing, one of the leading researchers of the study from the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences. It w ....

Ideas for future NASA missions searching for extraterrestrial civilizations

A researcher at the Instituto de Astrofísica de Canarias (IAC) is the lead author of a study with proposals for technosignatures -evidence for the use of technology or industrial activity in other parts of the Universe- for future NASA missions. The article, published in the specialized journal
Acta Astronautica, contains the initial conclusions of a meeting of experts in the search for intelligent extraterrestrial life, sponsored by the space agency to gather advice about this topic.
In the article, several ideas are presented to search for technosignatures that would indicate the existence of extraterrestrial civilizations, from the most humdrum, such as the presence of industrial pollution in the atmosphere or large swarms of satellites, to hypothetical gigantic space engineering work, such as heat shields to fend off climate change, or Dyson spheres for optimum use of the light from the local star.
