Strange structures at the center of the Milky Way, which behave like stars but act like gas clouds has been discovered by scientist - astronomers stumped. via Express UK: To add even more mystery to the "weird structures", they are able to survive despite being near to Sagittarius A* – The Milky Way's biggest supermassive black hole which has an intense gravitational pull. The objects are moving extremely fast and experts are having difficulty studying them because their view is obstructed by a wall of space dust. The galactic entities were first spotted by astronomers using the W. M. Keck Observatory in Hawaii and had to sift through 12 years worth of data. Dr Anna Ciurlo, a postdoctoral Scholar from University of California, Los Angeles (UCLA), said: "These compact dusty stellar objects move extremely fast and close to our Galaxy's supermassive black hole. "It is fascinating to watch them move from year to year. How did they get there? And what will they become? They must have an
