A new image of the Crystal Ball Nebula, a dazzling celestial object, has been captured by scientists using the Gemini Multi-Object Spectrograph. The instrument is mounted on the Gemini North telescope, located on Maunakea, a dormant volcano in Hawaii.
The Crystal Ball Nebula
The Crystal Ball Nebula, also known as NGC 1514, is a planetary nebula that lies about 1,500 light-years from Earth in the Taurus constellation. Planetary nebulae derive their name from the fact that they resemble planets when observed through a small telescope. These celestial objects form as dying stars eject their outer layers.
The image reveals the striking details of the planetary nebula, which contains a binary star system. One star in this binary system takes nine years to orbit the other, which is a relatively long time, and it’s part of the reason this planetary nebula has an unusual, cloudlike shape.
According to astronomer Travis Rector, the image was not a science target, but was chosen because it looks really cool. Rector said, “It’s a way to share with people just how amazing our universe is.”
The nebula’s colors appear vivid because of a filter in the spectrograph that allows specific wavelengths of light to pass through, corresponding to specific types of gas. The reddish hues come from hot hydrogen and the bright blue from hot oxygen, which are typically the gases most abundantly produced by planetary nebulae.
Observing the Nebula
Jan Cami, a professor of physics and astronomy at Western University in London, Ontario, compares planetary nebulae to butterflies because of their diverse colors and shapes. Cami said, “If you look at the same object with the James Webb Space Telescope, you would swear you’re actually looking at a completely different object.”
Planetary nebulae have a relatively short-lived dying phase — about 10,000 years. This brief time frame, astronomically speaking, allows scientists to observe the celestial objects as they reach the end of their life.
