Meet Cosmic Ray Energetics And Mass for the International Space Station (ISS-CREAM), an experiment designed to provide an unprecedented look at cosmic ray particles approaching energies of 1,000 trillion electron volts (1 PeV). ISS-CREAM detects these particles when they slam into the matter making up its instruments. They can distinguish electrons, protons and atomic nuclei as massive as iron as they crash through the detector stack.

Subscribe to Naked Science – http://goo.gl/wpc2Q1 During spaceflight we encounter the most deadly enemy of them all, radiation. Cosmic rays are immensely high-energy radiation, mainly originating outside the Solar System. Naked Science discovers the challenges humankind will have to overcome to journey to distant stars. One day we may face no choice but to leave Earth, forced by an ice age, pollution, or a meteorite, to find a new home elsewhere in the galaxy. The difficulties are daunting, humans evolved to live on Earth, not in space. Clip taken from the Naked Science documentary “Spacemen”. Watch it here – http://youtu.be/iufM_-aKxDM

A new study using observations from NASA's Fermi Gamma-ray Space Telescope reveals the first clear-cut evidence that the expanding debris of exploded stars produces some of the fastest-moving matter in the universe. This discovery is a major step toward meeting one of Fermi's primary mission goals. Cosmic rays are subatomic particles that move through space at nearly the speed of light. About 90 percent of them are protons, with the remainder consisting of electrons and atomic nuclei. In their journey across the galaxy, the electrically charged particles become deflected by magnetic fields. This scrambles their paths and makes it impossible to trace their origins directly. Through a variety of mechanisms, these speedy particles can lead to the emission of gamma rays, the most powerful form of light and a signal that travels to us directly from its sources. Two supernova remnants, known as IC 443 and W44, are expanding into cold, dense clouds of interstellar gas. This material emits gamma rays when struck by high-speed particles escaping the remnants. Scientists have been unable to ascertain which particle is responsible for this emission because cosmic-ray protons and electrons give rise to gamma rays with similar energies. Now, after analyzing four years of data, Fermi scientists see a gamma-ray feature from both remnants that, like a fingerprint, proves the culprits are protons. When cosmic-ray protons smash into normal protons, they produce a short-lived particle called a neutral pion. The pion quickly decays into a pair of gamma rays. This emission falls within a specific band of energies associated with the rest mass of the neutral pion, and it declines steeply toward lower energies. Detecting this low-end cutoff is clear proof that the gamma rays arise from decaying pions formed by protons accelerated within the supernova remnants.

Dr J (Dr Jasmina) is an astronomer and lecturer at the School of Physics and Astronomy explains the connection between cosmic rays, the most energetic particles in the Universe, and supernova remnants (SNRs). Supernova remnants are very likely responsible for creating lower-energy cosmic rays. Active Galactive Nuclei (ie, massive black holes in the centre of active galaxies) are also linked to cosmic rays with higher energies.

Cosmic rays are immensely high-energy radiation, mainly originating outside the Solar System. Upon impact with the Earth's atmosphere, cosmic rays can produce showers of secondary particles that sometimes reach the surface. Composed primarily of high-energy protons and atomic nuclei, they are of mysterious origin. keywords: Cosmic ray, Cosmic Rays, What Are Cosmic Rays?, What is a cosmic ray?, Do planets emit cosmic rays?, Are cosmic rays electromagnetic radiation?, Where do cosmic rays come from?, Cosmic Rays Definition Video, What can we learn from ultrahigh energy cosmic rays?.

Heidelberg Joint Astronomical Colloquium. 26 July 2016. Christoph Pfrommer (HITS, Heidelberg) "How cosmic rays shape galaxies"

Computational Plasma Astrophysics: July 26, 2016 Prospects in Theoretical Physics is an intensive two-week summer program typically designed for graduate students and postdoctoral scholars considering a career in theoretical physics (for 2014 only the program was one week in length). First held by the School of Natural Sciences at the Institute for Advanced Study in the summer of 2002, the PiTP program is designed to provide lectures and informal sessions on the latest advances and open questions in various areas of theoretical physics. One of the goals of the program is to help the physics community train the next generation of scholars in theoretical physics. A special effort is made to reach out to women and minorities, as well as to graduate students in small universities who typically do not have the same opportunities and access to leaders in the field as graduate students in large research institutions. Prospects in Theoretical Physics builds on the strong relationship of the research groups at the Institute and Princeton University, and many faculty members from the physics departments at both institutions are actively involved in the program together with scientists from neighboring institutions.
