When stars like our Sun use up all their fuel, they shrink to form white dwarfs. Sometimes such dead stars flare back to life in a super-hot explosion and produce a fireball of X-ray radiation. Using the eROSITA telescope on the SRG space observatory, a research team led by Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) has now been able to observe such an explosion of X-ray light for the very first time.
With a sophisticated combination of human and artificial intelligence, astronomers uncovered 1701 new asteroid trails in archival data of the Hubble Space Telescope spanning the past 20 years. While about one third could be identified and attributed to known objects, more than 1000 trails probably correspond to previously unknown asteroids.
MPE-Astronomers have found evidence that just before star formation, in the central region of a pre-stellar cloud, practically all heavy molecules freeze out on top of dust grains. The ALMA observations of the L1544 cloud in the constellation Taurus revealed that molecules containing nitrogen as well those containing carbon, oxygen and all elements heavier than helium, are stored in thick icy mantles around dust grains.
Using a combination of observed stars and a realistic model of the Milky Way, scientists at the MPE have found a new structure in our home galaxy. Just outside the Galactic bar, they found an inner ring of metal rich stars, which are younger than the stars in the bar.
