Bringing the building blocks of life down to Earth, from space

October 02, 2018
Astronomers from McMaster University and the Max Planck Institute for Astronomy have completed calculations that lead to a consistent scenario for the emergence of life on Earth, based on astronomical, geological, chemical and biological models. In this scenario, life forms a mere few hundred million years after Earth’s surface was cool enough for liquid water; the essential building blocks for life were formed in space during the formation of the solar system, and delivered to warm little ponds on Earth by meteorites. The new results have been published in the Proceedings of the US National Academy of Sciences. [more]

Testing the predictions of general relativity near the Milky Way’s central black hole

July 26, 2018
For the first time, astronomers have clearly detected the effects predicted by general relativity for the orbit of a star around the central supermassive black hole of our home galaxy. The measurements took advantage of the closest approach of one particular star to the black hole in May 2018. The required high precision was provided by the GRAVITY instrument at ESO’s Very Large Telescope, which exploits the wave properties of light to allow for highly accurate relative positions of point sources.

Detecting the boiling atmosphere of the hottest known exoplanet

July 02, 2018
Astronomers have found that the atmosphere of the hottest known exoplanet, the hot Jupiter-like planet KELT-9b, is "boiling off," with the escaping gas being captured by the host star. Using the CARMENES instrument at Calar Alto Observatory, Fei Yan and Thomas Henning of the Max Planck Institute for Astronomy in Heidelberg were able to detect the escaping hydrogen atmosphere of the planet. Their observations indicate a spread-out hydrogen envelope that is being pulled towards the host star.  [more]

Astronomers Witness the Birth of a Planet

July 02, 2018
Scientists from the Max Planck Institute for Astronomy (MPIA) in Heidelberg and the SPHERE instrument consortium at the Very Large Telescope of the European Southern Observatory (ESO) in Chile have discovered and characterised an extremely young exoplanet in a state of its formation. This gas giant with the designation PDS 70 b, with a mass equivalent to several Jupiters, was detected orbiting the star PDS 70 within a gap of its protoplanetary disk. This means that PDS 70 b is still in the vicinity of its birth place and likely still accumulating material. The observations provide a unique opportunity to test models of planet formation, and to learn about the early history of planetary systems, including our own solar system. [more]

Awards for MPIA researchers: Otto Hahn Medal for Paul Mollière. EPoS-Poster Award for Asmita Bhandare

June 27, 2018
Paul Mollière has been awarded the renowned Otto Hahn Medal by the Max Planck Society (MPG). The award at the annual meeting of the MPG in Heidelberg honored his comprehensive investigation of the structure of atmospheres of extrasolar planets and the analysis of their spectra. Asmita Bhandare received another award for her poster on star formation at the EPoS conference in Ringberg. [more]
