The central region of our Milky Way, the Galactic Bulge, is a rich host of variable high-energy X-ray and gamma-ray sources.
After a short introduction illustrating Integral’s place in ESA’s fleet of astronomy and astrophysics satellites, the movie looks inside the central bulge to reveal these dynamic sources, which include X-ray binary systems with either a black hole or a neutron star, pulsars and remnants of supernova explosions.
A number of these sources only shine brightly for a limited period of time – in some cases, they appear as a sudden bright flash and disappear shortly afterwards, whereas others are more persistent. The effect of this constantly changing environment gives the Galactic Bulge the appearance of a dramatic cosmic light show.
Zooming back out of the Milky Way shows a bird’s eye view of the known gamma and hard X-ray sources in our Milky Way.
The movie concludes with a stunning fly-through of the central part of the Galactic Bulge before returning to our Solar System and the orbit of Integral around Earth.
