Unveiling interstellar secrets!
A science team including #MPE's Konrad Dennerl captured the first X-ray images of comet 3I/ATLAS using @esa.int #XMMNewton. This goes back to 1996 when the #ROSAT mission discovered that comets emit X-rays.

A ROSAT X-ray image (false red color) superimposed on an optical image of a galaxy group. The image reveals hot gas confined by gravity, exceeding that of visible galaxies, indicating the presence of dark matter. This highlights the mystery surrounding dark matter's nature and abundance in the universe.

Hubble Space Telescope image reveals a lone neutron star (indicated by arrow). This massive star's existence challenges theories about neutron star structure and the limits of stellar mass before black hole formation. Observations from Hubble, ROSAT, and EUVE were combined to determine the star's size, temperature, and distance, providing insights into extreme conditions within neutron stars.

ROSAT's all-sky X-ray image reveals the Milky Way Galaxy's plane (horizontally), showcasing bright X-ray sources like the Vela Pulsar and Puppis supernova remnant. Extragalactic objects such as the Virgo Cluster and the Large Magellanic Cloud are also visible. Dark bands represent X-ray absorption by galactic gas and dust. The image uses color to represent different X-ray energy ranges.
