10 Δεκ 2008 · One of the stars has now completed a full orbit around the black hole. By watching the motions of 28 stars orbiting the Milky Way's most central region with admirable patience and amazing precision, astronomers have been able to study the supermassive black hole lurking there.
The new images zoom in 20 times more than what was possible before the VLTI and have helped astronomers find a never-before-seen star close to the black hole. By tracking the orbits of stars at the centre of our Milky Way, the team has made the most precise measurement yet of the black hole’s mass.
16 Απρ 2020 · The motion of a star orbiting Sagittarius A*, the supermassive black hole at the heart of our Milky Way galaxy, precisely matches that predicted by general relativity, a new study reports.
20 Νοε 2023 · The NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope’s reveals a portion of the Milky Way’s dense core in a new light. An estimated 500,000 stars shine in this image of the Sagittarius C (Sgr C) region, along with some as-yet unidentified features.
12 Μαΐ 2022 · The main panel of this graphic contains X-ray data from Chandra (blue) depicting hot gas that was blown away from massive stars near the black hole. Two images of infrared light at different wavelengths from NASA’s Hubble Space Telescope show stars (orange) and cool gas (purple).
25 Μαΐ 2022 · The black hole’s accretion disk is supplied by matter flowing from stars that orbit Sagittarius A* in a disk about 0.3 parsecs (one light year) across, he says.
12 Μαΐ 2022 · These calculations, done by tracking how stars orbit Sagittarius A*, provided strong evidence that the radio source is so massive and dense that it could be nothing but a black hole.
