Scientists have announced the discovery of nearly 300 gamma ray pulsars. The U.S. Naval Research Laboratory (NRL), in conjunction with the international Fermi Large Area Telescope Collaboration, ...

Gamma-rays are the highest energy (the shortest wavelength) type of electromagnetic radiation. They are classified as a type of an ionising radiation; with respect to alpha and beta particles they ...

Scientists have developed a game-changing perovskite material that can be used as a cheaper and highly efficient alternative to gamma-ray detectors. Perovskites are materials made up of organic ...

A scientist in California has taken steps toward a long-sought gamma ray laser by harnessing positronium bubbles in special liquid helium. Positronium is a volatile, short-lived atom that seems kind ...

Complex lead halides with the perovskite structure has been extensively studied in recent years in terms of radiation hardness. Many researchers found surprisingly high resistance of various ...

Gamma irradiation of food is a simple, reliable, and mature technology. However, more use of alternative irradiation technologies, based on electrically generated sources, would help complement the ...

A NASA-funded scientist has produced a new type of picture of the Earth from space, which complements the familiar image of our “blue marble”. This new picture is the first detailed image of our ...

The positions of the cataloged pulsars shown in a top-down view of the Milky Way. The red and orange symbols indicate millisecond pulsars, while the green and blue symbols indicate young, unrecycled ...
