Xray and infrared image of centre of Milky Way, with inset of black hole from EHT

The first snapshot of the cosmic monster in our galaxy opens more questions than it answers

There’s a monster swirling around the center of our galaxy, and its portrait has finally been revealed.

Overnight, the international crew of the Event Horizon Telescope (EHT) revealed an image of superheated gas flowing and falling in Sagittarius A* or Sgr A*, the supermassive black hole at the heart of the Milky Way.

It is the culmination of five years of simulations and data processing.

And while it may look a bit like a glazed donut, the new image has more to offer than meets the eye.

Space to play or pause, M to mute, left and right arrows to search, up and down arrows for volume.

Scientists reveal the image of a huge black hole in the center of the Milky Way.

On the one hand, this tells us that the black hole is 4 million times the mass of the Sun – a figure suspected by physicistsbut is now confirmed.

The black hole is also rotating, but it is oblique – slightly tilted in front of us.

But despite this veritable wealth of information about our galaxy’s black hole, there is still much to discover.

What’s so special about Sgr A*?

Well, on the one hand it is our a supermassive black hole.

“This is my home,” said Jessica Dempsey, an Australian astrophysicist and member of the EHT team.
