XMM-Newton has surveyed nearly 200 stars under formation to reveal, contrary to expectations, how streams of matter fall onto the young stars' magnetic atmospheres and radiate X-rays. The results defy ...

XMM-Newton, the most powerful X-ray observatory ever built and launched into space, marks its 10th anniversary on December 10th. XMM-Newton's observations have revolutionised the way we view the ...

ESA’s orbiting X-ray observatory XMM-Newton has discovered the most massive cluster of galaxies seen in the distant universe until now. The galaxy cluster is so big that there can only be a handful of ...

After a nearly 20-year-long game of cosmic hide-and-seek, astronomers using ESA’s XMM-Newton space observatory have finally found evidence of hot, diffuse gas permeating the cosmos, closing a puzzling ...

NASA’s Chandra X-ray Observatory and the ESA’s X-ray Multi-Mirror Mission (XMM-Newton) made their first observations ten years ago. The complementary capabilities of these observatories allow us to ...
