This breakthrough image is of the Vela Pulsar, a well-known gamma-ray source. A pulsar is a degenerate stellar object not much bigger than a city, and we are seeing it from 800 light-years away.

The Gamma-Ray Imager/Polarimeter for Solar flares, or GRIPS, payload launched into the sky on a giant balloon on Jan. 18, 2016. It will ride the winds around the South Pole for at least two weeks ...

The result? The highest-resolution image of gamma rays ever captured. As Vela pumped out gamma rays like “a lighthouse at night,” according to a press statement, this stack of film suspended ...

The gamma ray burst as seen by the European Space Agency’s XMM-Newton observatory. Image: ESA/XMM - Newton/M. Rigoselli (INAF) On October 9, 2022, a gamma ray burst brighter than any before seen ...

Instruments such as the Fermi Gamma-ray Space Telescope and the Imaging Atmospheric Cherenkov Telescopes have enabled researchers to observe gamma rays with unprecedented accuracy.

Gamma-ray image of the Fermi bubbles (blue) overlaid on a map of RR Lyrae stars (red) observed by the GAIA telescope. The shape and orientation of the Sagittarius dwarf (Sgr) match those of the ...

The gamma-ray burst, called GRB 211211A, lasted about a minute. ... “We image a source in different filters to obtain color information, which helps us determine the source’s identity.

A new paper on a two-minute long gamma-ray burst discovered last year is changing everything we know about these stellar events.

In 2019, the world was mesmerized by the first-ever image of a black hole, courtesy of the Event Horizon Telescope (EHT). The ...
