NGC 2392 is a bipolar double-shell planetary nebula.
About 5,000 gentle-years from Earth, the handsome nebula NGC 2392 shaped after the death of a critical particular person savor our Solar.
On this sonification, the image is scanned clockwise savor a radar. The radius is mapped to pitch, so gentle farther from the heart is bigger pitched. The account for of the nebula’s shell is seemingly to be heard within the rising and falling of pitch, punctuated by its spokes. Brightness controls the amount.

NGC 2392, identified as the Eskimo Nebula, Clown-faced Nebula, Lion Nebula, or Caldwell 39, is a double-shelled planetary nebula, with the extra distant gas having gentle the outer layers of a Solar-savor critical particular person handiest 10,000 years ago. The outer shell contains odd gentle-Twelve months-long orange filaments. The visible internal filaments are being ejected by a sturdy wind of particles from the central critical particular person. The NGC 2392 Nebula spans about 1/3 of a gentle-weight Twelve months and lies in our Milky Manner Galaxy, about 3,000 gentle years distant from Earth, toward the constellation of the Twins (Gemini).
To some, the mammoth NGC 2392 nebula resembles a particular person’s head surrounded by a parka hood, therefore the Eskimo Nebula nickname. In 1787, astronomer William Herschel found this odd planetary nebula. Extra recently, the Hubble Keep apart Telescope imaged the nebula in visible gentle, whereas the nebula change into once also imaged in X-rays by the Chandra X-ray Observatory. The featured combined visible-X ray image, exhibits X-rays emitted by central hot gas in purple. The nebula shows gas clouds so advanced that they don’t appear to be fully understood.
