On 10 December 1999, as XMM-Newton launched from Europe's spaceport in Kourou, French Guiana, no one was expecting that the mission would last for two decades.
During its 20 years in space, ESA's XMM-Newton X-ray observatory has made many exciting discoveries. But no one could have predicted that the very first observation of the spacecraft would be one of its most important.
ESA's X-ray observatory, XMM-Newton, has now spent 20 years in orbit. In those two decades it has made many scientific breakthroughs, helping bring X-ray astronomy into the main stream of astronomical investigation.
For the first time, astronomers have detected synchronised pulses of optical and X-ray radiation from a mysterious pulsar some 4500 light years away. The observations indicate that a new physical mechanism might be needed to explain the behaviour of fast-spinning sources like this one, known as transitional millisecond pulsars.
ESA's X-ray space telescope XMM-Newton has detected never-before-seen periodic flares of X-ray radiation coming from a distant galaxy that could help explain some enigmatic behaviours of active black holes.
Proposals are solicited for observations with XMM-Newton in response to the nineteenth Announcement of Opportunity, AO-19, issued 20 August 2019. This AO covers the period May 2020 to April 2021 and is open to proposers from all over the world. The deadline for proposal submission is 11 October 2019, 12:00 UTC.
