View of several proplyds within the Orion Nebula taken by the Hubble Space Telescope Star Formation Fireworks in Orion. The Orion Nebula is an example of a stellar nursery where new stars are being born. Observations of the nebula have revealed approximately 700 stars in various stages of formation within the nebula.
This image, made by the NASA/ESA Hubble Space Telescope in 2013, shows Barnard 33, the Horsehead Nebula, in the constellation of Orion (the Hunter), in infrared light.
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 .
The central star of the planetary nebula has a spectral type of [WC4], similar to that of a carbon-rich Wolf–Rayet star. [6] It is a pulsating star, meaning that its brightness varies regularly and periodically. In the case of NGC 1501's progenitor star, this is incredibly fast, with the star's brightness changing significantly in just half ...
IC 405 (also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31) is an emission and reflection nebula [1] in the constellation Auriga north of the celestial equator, surrounding the bluish, irregular variable star AE Aurigae. It shines at magnitude +6.0.
NGC 6826 (also known as Caldwell 15) is a planetary nebula located in the constellation Cygnus. It is commonly referred to as the "Blinking Planetary", although many other nebulae exhibit such "blinking". When viewed through a small telescope, the brightness of the central star overwhelms the eye when viewed directly, obscuring the surrounding ...
Jewel Bug Nebula, [citation needed] Gummy Bear Nebula [5] See also: Lists of nebulae NGC 7027, also known as the Jewel Bug Nebula or the Magic Carpet Nebula , [ 6 ] is a very young and dense planetary nebula [ 7 ] located around 3,000 light-years (920 parsecs ) from Earth in the constellation Cygnus .
Based on the expansion rate, the estimated age of the nebula is 3,080 years. [5] The central star of the planetary nebula is a subdwarf O star with a spectral type of sdO. [7] The best fit model for this star gives an effective temperature of 100 kK, with 5,250 times the luminosity of the Sun [5] and 60.5% of the Sun's mass. [6]
