NASA's Hubble Telescope sees a flash of light 10 times brighter than expected... what was it? Perhaps the birth of a magnetar. Jackson Ryan was CNET's science editor, and a multiple award-winning one ...

A discovery involving researchers at The University of Hong Kong (HKU) has, for the first time, revealed millisecond pulsations hidden within a powerful cosmic explosion known as a gamma-ray burst ...

Gamma rays are a broad category of high-energy photons, including everything with more energy than an X-ray. While they are often created by processes like radioactive decay, few astronomical events ...

Earth gets blasted by mild short gamma-ray bursts (GRBs) most days. But sometimes a giant flare like GRB 200415A arrives at our galaxy, sweeping along energy that dwarfs our sun. In fact, the most ...

How gamma-ray bursts (GRBs), the most powerful and spectacular explosions known in the universe since the Big Bang, fuel their high-energy radiations? What kind of physical reactions can trigger and ...

For the first time, astronomers have definitively spotted a flaring magnetar in another galaxy. These ultra-magnetic stellar corpses were thought to be responsible for some of the highest-energy ...

A notice was received by the scientists around Alexander Stefanescu in real time, pertaining to a brief outburst of high-energy radiation detected by the NASA Swift satellite. After observing the ...
