After all, black holes are not as destructive as we thought! 😮

Using our Very Large Telescope, astronomers have discovered, for the first time ever, a binary star close to our galaxy's supermassive black hole. Binary stars are extremely common throughout the galaxy but not close to the black hole, which makes this new system really interesting!

Named D9, it looks like a single dot, but its speed wobbles periodically back and forth, revealing that this is in fact two stars orbiting each other as they move together around the black hole.

The image shows a section of our galaxy, the Milky Way, in the night sky. This is where the supermassive blackhole and the newly discovered binary star around it are located. The Milky Way traverses the image diagonally and is a spectacle of light and darkness. Its millions of stars illuminate the picture, but light is often blocked by large dark clouds of gas and dust that create eerie shapes. It also contains stars and small nebulae of red, pink and blue colours. In the background, the sky is dark, but full of stars of different sizes and colours. The centre of the galaxy with the binary star appears in a close-up on one corner of the image. This is a pixelated mapping of the hydrogen emission of the region around the star pair D9. Bright orange to white patches represent high hydrogen levels (indicating stars), black, represents very low hydrogen emission. Most of the centre of the image is dark with a few wisps of dark orange. The black hole and the binary D9 are indicated.

First ever binary star found near our galaxy’s supermassive black hole

An international team of researchers has detected a binary star orbiting close to Sagittarius A*, the supermassive black hole at the centre of our galaxy.
