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.

23. Okt. 2011: #ROSAT, das Röntgenobservatorium und mit fast 2,5 t der bislang schwerste deutsche Satellit wird nach erfolgreicher Mission und 9 Jahren im All beim Wiedereintritt in die Erdatmosphäre zerstört.
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.

Unveiling the largest structures in the nearby Universe - discovery of the Quipu superstructure: arxiv.org/abs/2501.19236 -> Largest #superstructure in the nearby #universe discovered: www.mpg.de/24197951/lar... - data from the #ROSAT X-ray satellite have revealed a network of 68 galaxy clusters
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.

#ROSAT ist über dem Golf von Bengalen in die Erdatmosphäre eingetreten http://s.dlr.de/3449
Anybody actually see #ROSAT tonight? Presumably while it was still in the sky...?
There is currently no confirmation if pieces of #ROSAT debris have reached Earth's surface. www.dlr.de/en/rosat
Today, 23 October 2011, between 1:45 UTC and 2:15 UTC #ROSAT has re-entered Earth's atmosphere. www.dlr.de/en/rosat
Am 23. Oktober 2011 zwischen 3.45 Uhr und 4.15 Uhr MESZ ist der deutsche Satellit #ROSAT wieder in die Erdatmosphäre eingetreten.
I keep my fingers crossed that #ROSAT falls into the Pacific. And everybody in eastern Asia is fine.
Taking into account the most recent data, #ROSAT will not re-enter over Europe, Africa or Australia. www.dlr.de/rosat-en
Auf Grundlage der aktuellen Daten wird #ROSAT nicht über Europa, Afrika und Australien wiedereintreten.
Latest prediction on #ROSAT re-entry: between Sunday 23 October 2011, 0:30 UTC and 03:30 UTC www.dlr.de/en/rosat
@Uelii Latest prediction on #ROSAT re-entry: between 22 October 2011, 23:30 UTC & 23 October 2011, 05:00 UTC. http://www.dlr.de/en/rosat

Ahh, heavy traffic on dlr.de server due to @NASA RT. #ROSAT
Wer hat den gerade dlr.de gepritloved? #ROSAT
