Despite losing one of its most popular cameras last month, the Hubble Space Telescope is still proving its worth, capturing a new round of awe-inspiring images with its remaining camera (see related images of Hubble's top discoveries).

On Tuesday NASA released this new shot of a dying star—a white dwarf shown as a bright dot near the center of nebula NGC 2440—that was once similar to our sun.

Low- to medium-size stars like our sun usually end their lives as white dwarfs. Once most of a star's hydrogen has been converted to helium, the star enters the red giant phase, eventually expelling its outer material to form a nebula of stellar debris. The hot core left behind is a white dwarf.
