It has been photographed multiple times by the Hubble Space Telescope since its launch in 1990. [10] [11] Prior to these observations, NGC 7027 was thought to be a protoplanetary nebula with the central star too cool to ionize any of the gas, but it is now known to be a planetary nebula in the earliest stage of its development.

The world’s most powerful space telescope, NASA’s James Webb Space Telescope, has just released the sharpest infrared images to date of the Horsehead Nebula, a small dark nebula in the ...
NGC 3132 (also known as the Eight-Burst Nebula, [2] the Southern Ring Nebula, [2] or Caldwell 74) is a bright and extensively studied planetary nebula in the constellation Vela. Its distance from Earth is estimated at 613 pc or 2,000 light-years .
Only 36 stars were known to be in this nebula but the Chandra telescope increased the number of known stars to 160. Lagoon Nebula: 110 ly (34 pc) [58] H II region: Veil Nebula: 100–130 ly (31–40 pc) [59] Supernova remnant: Located in the Cygnus Loop: NGC 3576: 100 ly (31 pc) [60] Emission nebula: N41: 100 ly (31 pc) [61] Emission nebula ...
This image, taken with the VLT Survey Telescope hosted at ESO’s Paranal Observatory, shows the beautiful nebula NGC 6164/6165, also known as the Dragon’s Egg. The nebula is a cloud of gas and ...
The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion, and is known as the middle "star" in the "sword" of Orion.
The Helix Nebula (also known as NGC 7293 or Caldwell 63) is a planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, most likely before 1824, this object is one of the closest of all the bright planetary nebulae to Earth. [3] The distance, measured by the Gaia mission, is 655±13 light-years. [4]
