Chandra finds Black Hole at the centre of the Milky Way spraying high-energy jet of particles

Sgr-A, the supermassive black hole at the centre of our galaxy ejects powerful jets of charged particles. This image is a composite of Chandra images in X-ray (shown in purple) with Radio images from the VLA (blue). Image credit: X-ray: NASA/CXC/UCLA/Z. Li et al; Radio: NRAO/VLA

Galaxies around the universe are now known to have supermassive black holes at their cores, and these SMBH’s are known for their powerful jets of high energy partcicles streaming away along their north and south poles.  Recently, the Chandra X-ray space telescope has been peering through the dense wall of gas and dust which lies between us and our own SMBH, and has finally confirmed that we too have one of these vast jets in our own Milky Way galaxy.High … Continue reading →

Milky Way surrounded by hot gas

This artist's illustration shows an enormous halo of hot gas (in blue) around the Milky Way galaxy. Also shown, to the lower left of the Milky Way, are the Small and Large Magellanic Clouds, two small neighboring galaxies. The halo of gas is shown with a radius of about 300,000 light years, although it may extend significantly further. Credit: Illustration: NASA/CXC/M.Weiss; NASA/CXC/Ohio State/A Gupta et al

Recent observations by NASA’s Chandra have found much of the Milky Way’s missing mass in the form of a vast halo surrounding the galaxy. It has been known for many decades that the amount of material which we can see in a galaxy is not enough to account for the speeds at which various stars and clouds orbit the centre. Objects towards the edge should move slowly and objects near the core should move rapidly, which is what we observe … Continue reading →
