Physicists Successfully Observe 'Second Face' of Nickel-66 Nuclei

To some degree of approximation, atomic nuclei look like spheres which in most cases are distorted to a greater or lesser extent. When the nucleus is excited, its shape may change, but only for an extremely brief moment, after which it returns to its original state.

NASA's Gamma-Ray Telescopes Observe a Trap that Concentrates the Highest-Energy Cosmic Rays

A collective study on the data obtained from NASA's Fermi Gamma-ray Space Telescope and the High Energy Stereoscopic System (H.E.S.S.), a ground-based observatory in Namibia, reveals that the center of the Milky Way comprises of a "trap" that is capable of concentrating some of the highest-energy cosmic rays, among the fastest particles present in the galaxy.
