The Calabash Nebula | Hubble)
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/European Space Agency 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 a million kilometers an hour.
