  We Just Discovered The Milky Way Isn’t Actually a Flat Disc After All Apparently our galaxy really likes to boogie. It has, on several occasions, enjoyed a Monster Mash; now it’s been caught doing the Twist. A new study has revealed that the Milky Way isn’t a nice, neat, flat disc – it’s seriously…

Most Detailed Observations of Material Orbiting close to a Black Hole – ESO’s GRAVITY instrument confirms black hole status of the Milky Way centre ESO’s exquisitely sensitive GRAVITY instrument has added further evidence to the long-standing assumption that a supermassive black hole lurks in the centre of the Milky Way. New observations show clumps of…
