A telescope in Hawaii has captured a spectacular new view on a
distant nebula, revealing a glowing swirl of gas that is at the center
of an unsolved mystery surrounding the nebula’s birth.
The photo from the Gemini North telescope in Hawaii shows the complex
planetary nebula Sharpless 2-71, which is located about 3,260
light-years from Earth in the constellation Aquila (The Eagle).
Planetary nebulas form when a star like our sun exhausts its hydrogen
fuel. The star’s outer layers expand and cool, creating a huge envelope
of dust and gas. Radiation flowing from the dying star ionizes this
envelope, causing it to glow.
