Integral sees blast traveling with gravitational waves

Press/Media: Press / Media

Description

ESA’s Integral satellite recently played a crucial role in discovering the flash of gamma rays linked to the gravitational waves released by the collision of two neutron stars.


On 17 August, a burst of gamma rays lit up in space for almost two seconds. It was promptly recorded by Integral and NASA’s Fermi satellite.


Such short gamma-ray bursts are not uncommon: Integral catches about 20 every year. But this one was special: just seconds before the two satellites saw the blast, an entirely different instrument was triggered on Earth.
