Fermi Gamma-ray Space Telescope

The signal originated from the direction of the constellation Sagitta, and travelled an estimated 1.9 billion years to reach Earth, NASA said.

NASA has used certain characters from modern myths such as the "Hulk" and "Godzilla" to name its new set of 21 gamma-ray constellations constructed in celebration of its Fermi Gamma-ray Space Telescope's 10th year of operations.

NASA's Fermi gamma-ray space telescope has found a signal at the centre of the neighbouring Andromeda galaxy that could be coming from dark matter, an unknown substance that makes up most of the universe, according to a study.

Astronomers using data from NASA's Fermi Gamma-ray Space Telescope have detected hints of periodic changes in the brightness of a so-called "active" galaxy, whose emissions are powered by a supersized black hole.
