NASA, ESA, and A. Nota (STScI/ESA) By Leah Crane The Small Magellanic Cloud, one of our closest galactic neighbours, is dying. New observations show that for every sun-sized star that the galaxy forms, it blows away almost ten times as much mass in the form of cold hydrogen gas. Theories have predicted that dwarf galaxies like the Small Magellanic Cloud (SMC) should be constantly leaking gas, but we have never studied those gas leaks in detail before. Now,
