An curved arrow pointing right. NASA's Fermi Gamma-ray Space Telescope can now detect solar flares occuring on the side of the sun it cannot see. This could help scientists better understand solar ...

That isn’t the only way to measure gamma radiation, though, and [Alan] has a great circuit to measure even relatively weak radiation sources. It uses a very small photodiode, and draws so little ...

and gamma-ray bursts. This is expected to boost India's standing in global cosmic ray research. The telescope measures 21 metres in diameter, weighs 175 tonnes, and features a reflector area of ...

The Cherenkov Telescope Array (CTA) is a project to build a new generation ground-based gamma-ray observatorium. It will consist of two arrays of Imaging Atmospheric Cherenkov telescopes, one being ...

For over a decade, a star system on the verge of unleashing a deadly gamma ray burst appeared to have its guns trained on Earth. The so-called "Death Star," which is also famed for looking like a ...

It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will ...

ABSTRACT We present the technical details of the gamma‐ray burst (GRB) alert system of the Katzman Automatic Imaging Telescope (KAIT) at Lick Observatory and the successful observations of the GRB ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film ...
