Behind the scenes of protostellar disc formation

11 July 2016 Astronomy Now

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.

VLA reveals earliest stages of planet formation

18 March 2016 Astronomy Now

New images of a young star called HL Tauri made with the Karl G. Jansky Very Large Array (VLA) reveal what scientists think may be the very earliest stages in the formation of planets. The scientists used the VLA to see unprecedented detail of the inner portion of a dusty disc surrounding the star, some 450 light-years from Earth.
