A glittering artist’s impression of a disk galaxy transforming into an elliptical galaxy.

Earlier this month, astronomers announced that galaxies may be able to change their shape without colliding with other galaxies. The process was illustrated in this glittering artist’s impression of a disk galaxy transforming into an elliptical galaxy. In the center sits a massive pool of gas and dust, out of which new stars are born. As these stars accumulate, they spin out from the center, slowly changing the galaxy's shape into its ultimate elliptical form. (NAOJ)
