paving-the-way-for-the-next-generation-survey-telescope 4MOST is a new wide-field spectroscopic survey facility under development for the four-metre-class Visible and Infrared Survey Telescope for Astronomy (VISTA) at Paranal in Chile. It will be the largest spectroscopic survey facility of its kind in the Southern hemisphere and address today's most...

stellar-wind-of-old-stars-reveals-existence-of-a-partner We humans don’t live long enough to realise it, but stars are also born, they age and they die. It's a process that takes billions of years. As a star gets older, it becomes bigger and colder and turns redder, hence the name ‘red giants’. Our sun will also become such a red giant in four and a half...

hundreds-of-thousands-of-new-galaxiesAn international team of more than 200 astronomers from 18 countries including scientists from the Hamburg Observatory has published the first phase of a major new radio sky survey at unprecedented sensitivity using the Low Frequency Array (LOFAR) telescope. The survey reveals hundreds of thousands of...

discovery-of-helium-traces-atmospheric-escape-in-hot-exoplanets The Solar System gas giants Jupiter and Saturn orbit our Sun at large distances, where solar light carries only little heat. The situation is quite different in extrasolar planetary systems like HD 189733 and WASP-69. Here two gas giants orbit their stars at such small distances that a complete...

our-stellar-neighbourhood-expandsAstronomers from the Hamburg Observatory were involved in the discovery of a new planet. As part of an international research team led by the Institut de Ciències de l'Espai (ICE, CSIC), they have found a planet in orbit of Barnard's star. Barnard's star is a so-called red dwarf and after the...

cosmic-heating-by-magnetic-fields Could magnetic fields have heated up the Universe while it was very young? This question was addressed with state-of-the art numerical simulations by astrophysicists at the Hamburg Observatory and the University of Manchester. Generally, magnetic fields play an important role in galaxies and are...

longstanding-problem-of-star-formation-solved-generation-of-star-forming-molecular-clouds-by-parker-instability Molecular clouds are the birthplaces of stars in galaxies. Those clouds are extremely cold (about minus 260 degree Celsius). Therefore, the low internal thermal pressure allows the condensation of stars out of these clouds due to their own gravitational weight. Molecular clouds are also permeated by...

hunting-radio-galaxies-in-the-outback-of-the-universe Since 2015 an antenna field of the largest European radio telescope LOFAR is operating in Norderstedt (Schleswig-Holstein). This LOFAR station is operated by the Hamburger Sternwarte (Universität Hamburg) and the Fakultät für Physik of the University of Bielefeld. Together with  50 similar...
