The mystery at the heart of the Milky Way has finally been solved. This morning, at simultaneous press conferences around the world, the astronomers of the Event Horizon Telescope (EHT) revealed the first image of Sagittarius A*, the supermassive black hole at the center ...
It was back in 2019 when scientists joined forces to produce the first ever picture of a black hole. Now they’ve done it again using the same technology. This new block hole discovery is not as big as the first one, yet it’s a lot closer to us. It’s at the center of our Mi...
The formation of our Milky Way can be split up qualitatively into different phases that resulted in its structurally different stellar populations: the halo and the disk components1,2,3. Revealing a quantitative overall picture of our Galaxy’s assembly requires a large sample of stars with very ...

The EHT team has also attempted to image Sagittarius A*, the black hole at the center of the Milky Way galaxy. That data is still being processed, but we could see it soon. And in case you're wondering how radio signals create an image, given that we don't typically get great pict...
Using a telescope the size of the planet, astronomers have captured the first image of this space oddity. Here's why that matters.
was Sagittarius A*, the black hole at the centre of the Milky Way, which has a mass of about four million suns. The second target, which yielded the image, was a supermassive black hole in the galaxy M87, into which the equivalent of six billion suns of light and matter has ...
Sagittarius A* is by far the closest SMB (a mere 26,000 light-years away), but of course there’s a galaxy in the way. To see it we have to look long-ways through the disk of the Milky Way, which is full of stuff. M87* on the other hand is a ...
At the heart of the Milky Way, there's a supermassive black hole that feeds off a spinning disk of hot gas, sucking up anything that ventures too close -- even light. We can't see it, but its event horizon casts a shadow, and an image of that shadow could help answer som...
To put that in perspective, our Solar System takes about 230 million years to circle the centre of the Milky Way. Eventually, astronomers speculated that these bright spots were in fact "black holes"—a term coined by American physicist John Archibald Wheeler in the mid-1960s—surrounded by ...
