The Israel Missile Defense Organization (IMDO), in the Directorate of Defense Research and Development of the Israel Ministry of Defense, and the U.S. Missile Defense Agency (MDA) have begun the development of the Arrow 4 interceptor. Arrow 4 will be the next generation of endo-exoatmospheric interceptors for the Arrow Weapon System, which today consists of Arrow 2 and Arrow 3 interceptors.

Astrophysicists have traced a subatomic particle called a neutrino to its cosmic origins, a tidal disruption event located some 700 million light-years from Earth.
The new research - published Monday in the journal Nature Astronomy - suggests the violent destruction of a faraway star by a supermassive black hole was powerful enough to send a tiny, near-frictionless particle racing acr
