ALMA captures a bubble of ejected material around U Antliae, an ageing star

Firstpost  

Astronomers have used the Atacama Large Millimeter/submillimeter Array in Chile to capture a breathtaking image of a shell of ejected material around U Antliae, star about 900 light years away from the Earth. The star actually has two shells of ejected material from two events where the ageing star rapidly expelled large amounts of matter. Researchers can study the thin and delicate shell with precision because the ALMA astronomical instrument not only captures images, but also produces a three dimensional dataset known as a data cube. The bubbles of ejected material like the one seen around U Antliae help recycle matter and contribute up to 70 percent of the dust in the interstellar medium.
