Hubble captures brilliant star death in 'rotten egg' nebula
The Calabash Nebula, pictured here—which has the technical name OH 231.8+04.2—is a spectacular example of the death of a low-mass star like the sun. This image taken by the NASA/ESA Hubble Space Telescope shows the star going through a rapid transformation from a red giant to a planetary nebula, during which it blows its outer layers of gas and dust out into the surrounding space. The recently ejected material is spat out in opposite directions with immense speed—the gas shown in yellow is moving close to one million kilometers per hour (621,371 miles per hour).

The nebula is also known as the Rotten Egg Nebula because it contains a lot of sulphur, an element that, when combined with other elements, smells like a rotten egg—but luckily, it resides over 5,000 light-years away in the constellation of Puppis.
