First-ever image of Milky Way’s supermassive black hole

This week, astronomers revealed the first image of the supermassive black hole at the heart of a galaxy not so far, far away — our home galaxy, the Milky Way.

Scientists had previously seen stars orbiting around something invisible, compact, and very massive at the centre of the Milky Way. Known as Sagittarius A* or Sgr A*, this object was strongly believed to be a black hole.

Astronomers turn robotic eyes on our cosmic home, the Milky Way Galaxy

2 FPS units prior to robot installation in a room

Thanks to a breakthrough robotic innovation, an international collaboration which includes the University of Toronto has advanced the Sloan Digital Sky Survey (SDSS), a 20-year-long research project that has been investigating the structure and evolution of our cosmic home, the Milky Way Galaxy.

A new Focal Plane System (FPS) is at the heart of the fifth phase of the project, SDSS-V. The FPS…
