(2016-11-03)

Science: Ambassadors from distant galaxies
Cosmic rays of very high energy have their origin outside of our own galaxy, the Milky Way. This is suggested by a study of the angles of incidence of more than 30,000 particles at the Pierre Auger Observatory in Argentina, which is now reported in the Science journal. This finding of the KIT-managed largest experiment measuring cosmic rays worldwide is another important step on the way towards answering fundamental questions relating to the origin of the universe.

Cloud in a chamber
Everybody knows that clouds markedly influence weather and climate, but is this influence changing with time? Over the last several years some evidence was found that past changes in cosmic ray intensity have correlated with fluctuations of temperature and precipitation on Earth. There could be a causal link of these quantities via the formation of clouds, because the cosmic rays create ions in the atmosphere which may grow into aerosol particles that act as the initial point for cloud formation.

Microscopic 'clocks' time distance to source of galactic cosmic rays
Most of the galactic cosmic rays reaching Earth come from nearby clusters of massive stars, according to new observations from NASA's ACE spacecraft. The distance between the cosmic rays' point of origin and Earth is limited by the survival of a radioactive isotope of iron, Fe-60, which has a half life of 2.6 million years. These tiny clocks indicate there was a source within spitting distance of Earth within the past few million years. (2016-04-21)

A new mechanism for producing cosmic gamma rays from starlight is proposed
In 2002, when astronomers first detected cosmic gamma rays coming from the constellation Cygnus, they were surprised and perplexed. The region lacked the extreme electromagnetic fields that they thought were required to produce such energetic rays. But now a team of theoretical physicists propose a mechanism that can explain this mystery and may also help account for another type of cosmic ray, the high-energy nuclei that rain down on Earth in the billions. (2007-03-19)

One of the biggest mysteries in astroparticle physics has been the origins of ultrahigh-energy cosmic rays, very high-energy neutrinos, and high-energy gamma rays. Now, a new theoretical model reveals that they all could be shot out into space after cosmic rays are accelerated by powerful jets from supermassive black holes. The model may set a new milestone on the path toward solving the half-century-old enigma of the origin of the highest-energy particles in the universe. (2018-01-22)
