The Hubble Telescope and Chandra X-ray Observatory saw an enigmatic intermediate-mass black hole lighting up in X-rays, ...

Additional data from Hubble and Spitzer is included, along with supporting data from XMM-Newton and ESO’s New Technology Telescope. (X-ray: purple and blue; infrared/optical: red, green, blue) ...

Using the XMM-Newton telescope, astronomers have discovered a vast 23 million light-year-wide tendril connecting galactic clusters and containing much of the universe's missing matter.

The XMM Newton space telescope has seen a feeding supermassive black hole as it throws a galaxy-sized tantrum ‘flipping over the table’ and preventing its parent galaxy from birthing new stars.

The XMM-Newton space observatory took off from Kourou, French Guiana one year ago this week. XMM is a space telescope that looks at the very hottest regions and most violent events in space. In ...

The agency said that data from the Hubble Space Telescope and Spitzer Space Telescope, and the European Space Agency XMM-Newton and the European Southern Observatory's New Technology Telescope was ...

These powerful telescopes, alongside a few others, including the European Space Agency’s XMM-Newton observatory, recently had their imagery compiled by NASA image scientists, to produce unique ...

XMM-Newton, a European Space Agency and NASA-operated space telescope, has imaged a vast cosmic "Cloverleaf" to uncover its mysterious origins.

XMM-Newton’s Deep Field image features, for instance, an object with a redshift of 2.5 – representing a distance some ten thousand million light-years away.
