Southern Crab Nebula - 20190418

Summary

[edit]
Description
English: Hubble Celebrates 29th Anniversary with a Colorful Look at the Southern Crab Nebula

Rich colors of the gases in the nebula's filaments correspond to glowing hydrogen (green), sulfur (red), nitrogen (orange), and oxygen (blue).

This Hubble image shows the results of two stellar companions in a gravitational waltz, several thousand light-years from Earth in the southern constellation Centaurus. The stellar duo, consisting of a red giant and white dwarf, are too close together to see individually in this view. But the consequences of their whirling about each other are two vast shells of gas expanding into space like a runaway hot air balloon. Both stars are embedded in a flat disk of hot material that constricts the outflowing gas so that it only escapes away above and below the stars. This apparently happens in episodes because the nebula has two distinct nested hourglass-shaped structures. The bubbles of gas and dust appear brightest at the edges, giving the illusion of crab legs. The rich colors correspond to glowing hydrogen, sulfur, nitrogen, and oxygen. This image was taken to celebrate Hubble's 29th anniversary since its launch on April 24, 1990.
