Photo: Fluorescent planetary nebula 4,900 light-years away

The Hubble Space Telescope captured an image of planetary nebula NGC 3918, which is a part of the the Centaurus constellation about 4,900 light-years from Earth, according to NASA.

Between the lines: A planetary nebula is a cloud of colorful gasses which surrounds a dying star — known as a red giant, according to NASA. The remnants of the star give off the light, which reflects in the gasses and creates the beautiful, dramatic colors seen in the photo.
