GRAVITY instrument breaks new ground in exoplanet imaging

The GRAVITY instrument on ESO's Very Large Telescope Interferometer (VLTI) has made the first direct observation of an exoplanet using optical interferometry. This method revealed a complex exoplanetary atmosphere with clouds ...

Neural networks predict planet mass

To find out how planets form, astrophysicists run complicated and time-consuming computer calculations. Members of the NCCR PlanetS at the University of Bern have now developed a totally novel approach to speed up this process ...

Astrophysicists study asteroid 3200 Phaethon

Polarimetric investigation of a near-Earth asteroid Phaethon was carried out in December 2017 on its closest approach to the Earth. The study was conducted in collaboration with scientists from the Ussuriysk Astrophysical ...

Observations challenge cosmological theories

Recent observations have created a puzzle for astrophysicists: Since the Big Bang, fewer galaxy clusters have formed over time than were actually expected. Physicists from the university of Bonn have now confirmed this phenomenon. ...

OTELO reveals a population of "ghost galaxies" in the universe

The OSIRIS instrument on the Gran Telescopio Ganarias has made the deepest survey of galaxies to date, the OSIRIS Tunable Emission Line Object survey (OTELO), and the results could change what we currently know about the ...
