For a long time the formation of protostellar discs — a prerequisite to the formation of planetary systems — has defied theoretical astrophysicists. Now, researchers have made a breakthrough in our understanding of how protoplanetary discs form, demonstrating that chemistry and microphysics are crucial to the fundamental processes underlying star and planet formation.
Zooming in on black holes is the main mission for the newly installed GRAVITY instrument at ESO’s Very Large Telescope in Chile. During its first observations, GRAVITY successfully combined starlight using all four 1.8-metre Auxiliary Telescopes. The first observations using GRAVITY with the four 8-metre VLT Unit Telescopes are planned for later in 2016.
