Scientists have discovered that the Sun produces higher energy light than was thought possible. An unusual type of telescope detected gamma rays with energies of over 1 tera electron volt, at ...

While the series of events that generated GRB 221009A (supernova explosion or creation of a black hole) remains undetermined, the gamma-ray source is located almost 2 billion light-years away ...

An unexpected and unexplained gamma-ray signal from beyond the Milky Way found among 13 years of NASA Fermi Telescope data could be linked to another cosmic mystery.

Gamma-ray bursts, or GRBs, are intense blasts of gamma rays—the highest-energy form of light—that typically last from a fraction of a second to a few minutes in length.

Gamma rays travel through the vacuum of space at the speed of light, with wavelengths so minuscule that they can pass through the space within the atoms of a detector.

A huge surge of gamma-ray energy from space caused electric currents to flow through the surface of the Earth on October 9, scientists have said.. This gamma-ray burst, named GRB221009A, is the ...

Before CTAO, VERITAS was the world's most sensitive very-high-energy-gamma-ray observatory that could detect brief flashes of ...

The bright flash of gamma-ray light was first detected by NASA’s Neil Gehrels Swift Observatory on October 19, 2019. The explosion lasted just over a minute — considered long, ...

NASA said that GRB 221009A is only the 7th gamma-ray burst we’ve detected that creates these x-ray rings. The echoes came from dust located between 700 and 61,000 light-years away. The AAS ...

The first ever space telescope, the Orbiting Astronomical Observatory 2 (OAO-2), was launched into the low Earth orbit in ...

Using NASA’s Fermi Gamma-ray Space Telescope, astronomers have identified seven rare stellar binary systems in which a neutron star is eclipsed by its stellar companion. This allowed the international ...
