A Cold Super-Earth in our Neighbourhood

November 14, 2018
An international group of astronomers, involving the Max Planck Institute for Astronomy (MPIA) in Heidelberg, has succeeded in detecting a planet around Barnard's star, which is only six lightyears away. The planet has just over three times the mass of Earth and is slightly colder than Saturn. The discovery was made by measuring the periodic change in the radial velocity of the parent star. The spectrograph CARMENES, developed to a large part by the MPIA, played an important role in this discovery. [more]

Tracking the interstellar object ‘Oumuamua to its home

September 25, 2018
A team of astronomers led by Coryn Bailer-Jones of the Max Planck Institute for Astronomy has tracked the interstellar object ‘Oumuamua to several possible home stars. The object was discovered in late 2017 – this was the first time astronomers have been able to observe an astronomical object from another star system visiting our own Solar System. Bailer-Jones and his colleagues used data from the ESA astrometry satellite Gaia to find four plausible stars where ‘Oumuamua could have begun its long journey, more than a million years ago. [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.
