Latest XMM-Newton observatory Stories
Two ESA observatories have combined forces to show the Andromeda Galaxy in a new light. Herschel sees rings of star formation in this, the most detailed image of the Andromeda Galaxy ever taken at infrared wavelengths, and XMM-Newton shows dying stars shining X-rays into space.
Observations of faint and distant galaxy groups made with the European Space Agency's XMM-Newton observatory have been used to probe the evolution of dark matter.
While astronomers have studied lightweight and heavyweight black holes for decades, the evidence for black holes with intermediate masses has been much harder to come by.
Using a â€˜radar-gunâ€™ technique, typical of police speed-traps, scientists have clocked three separate clumps of hot iron gas whipping around a black hole at 30 000 kilometres per second, about a tenth of the speed of light.
