NGC 2867 (also known as Caldwell 90) is an elliptical [5] Type II [7] planetary nebula in the southern constellation of Carina, just over a degree to the NNW of the star Iota Carinae. [8] It was discovered by John Herschel on April 1, 1834.
Kronberger 61, also known as the "soccer ball", is a planetary nebula discovered by an amateur astronomer in January, 2011, with the newer images having been taken by the Gemini Observatory. [2] The nebula is named for Austrian Matthias Kronberger, [3] who is a member of the amateur group Deep Sky Hunters. The object is estimated to lie 13,000 ...
NGC 6326 is a complex and irregularly structured planetary nebula located in the constellation Ara.It was discovered by Scottish astronomer James Dunlop on 26 August 1826. . NGC 6326 is the result of the ejected material from the central binary star, which is nearing the end of its l
A typical planetary nebula is roughly one light year across, and consists of extremely rarefied gas, with a density generally from 100 to 10,000 particles per cm 3. [42] (The Earth's atmosphere, by comparison, contains 2.5 × 10 19 particles per cm 3.) Young planetary nebulae have the highest densities, sometimes as high as 10 6 particles per ...
NGC 6565 (also known as ESO 456-70) is a planetary nebula in the constellation of Sagittarius. The object formed when a star ejected its outer layers during the late stages of its evolution . The remnant core of the star, a white dwarf , is emitting vast amounts of ultraviolet radiation that ionizes , or excites, the gas surrounding it, making ...
NGC 6741, also known as the Phantom Streak Nebula, is located about 7000 light-years away in the constellation of Aquila (the Eagle). NGC 6741 is classed as a planetary nebula, though no planets are responsible for this billowy cloud; the term came about in the 18th century because the round gas shells resembled the Solar System's outer giant planets in astronomers' telescopes.
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 .
NGC 6751, also known as the Glowing Eye Nebula, [2] is a planetary nebula in the constellation Aquila. It is estimated to be about 6,500 light-years (2.0 kilo parsecs ) away. [ 2 ]
