Notes for Editors

Integral was launched on 17 October 2002 by a Proton/Blok-DM rocket from Baikonur, Kazakhstan. It operates in an elliptical 72-hour orbit around Earth.

Equipped with two gamma-ray telescopes, an X-ray monitor and an optical camera, all four of Integral’s instruments point simultaneously at the same region of the sky to make complementary observations of high-energy sources.

With an initial mission duration of two years, it continues to operate very successfully after ten years and a further extension beyond 31 December 2014 is under consideration.

Galactic Centre through Integral’s eyes:

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.

A journey through some of Integral’s key science highlights. From rare breeds of binary stars and pulsars with extraordinary magnetic fields, to the annihilation of matter with antimatter and the feeding habits of black holes, Integral has been uncovering the secrets of the most energetic phenomena in the Universe.

This slideshow of artist impressions was first released on Monday as our Space Science Image of the Week.
