The discovery represents the first evidence that low-mass T.Tauri stars, which are less than 10 million years old, can emit gamma radiation. When you purchase through links on our site, we may earn an ...

Gamma rays can only be detected by sensors made of dense metals and takes over six feet (1.8 meters) of concrete to block. When you purchase through links on our site, we may earn an affiliate ...

A tremendous cosmic explosion 2.4 billion light years away temporarily changed the electric field in Earth’s ionosphere (the electrically-charged upper layer of our atmosphere that helps shield life ...

Gamma-ray burst, GRB 250702B, lasting for a record-breaking seven hours, stunned researchers Researchers have discovered a ...

Astronomers have witnessed a young, sun-like star blasting out high-energy gamma radiation for the first time. The observation represents the first evidence that this type of low-mass star, called a T ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...

Thunderstorms are far more radioactive than previously thought, routinely producing gamma rays—the highest-energy form of electromagnetic radiation typically associated with supernovas and other ...

The afterglow of the gamma-ray burst as captured by the Neil Gehrels Swift Observatory's X-ray telescope. NASA/Swift/A. Beardmore (University of Leicester) On October 9, astronomers detected a bright ...

LOS ALAMOS, N.M., August 21, 2013—The High-Altitude Water Cherenkov (HAWC) Gamma Ray Observatory has begun formal operations at its site in Mexico. HAWC is designed to study the origin of very ...

Thunderstorms in the tropics are literally radioactive, according to a team of researchers that recently used a retrofitted spy plane to survey the phenomena. The team’s research was published in two ...
