MAMMOTH-1: 1,441,000 ly (442,000 pc) [7] Enormous Lyα nebula (ELAN) The nebula is associated with the galaxy overdensity BOSS1441, [7] which is a protocluster at z=2.3. The nebula represents the circumgalactic medium. Its emission is ...
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 .
This is a list of the brightest natural objects in the sky. This list orders objects by apparent magnitude from Earth , not anywhere else . This list is with reference to naked eye viewing; all objects are listed by their visual magnitudes, and objects too close together to be distinguished are listed jointly.
NGC 3918 is a bright planetary nebula in the constellation Centaurus, nicknamed the "Blue Planetary" or "The Southerner". It is the brightest of the far southern planetary nebulae. This nebula was discovered by Sir John Herschel in March 1834 and is easily visible through small telescopes.
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. It is one of the brightest nebulae and is visible to the naked eye in the night sky with an apparent magnitude of 4.0.
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.
The Cosmic Cliffs at the edge of NGC 3324, one of the first images taken by the James Webb Space Telescope. The Carina Nebula [7] or Eta Carinae Nebula [8] (catalogued as NGC 3372; also known as the Great Carina Nebula [9]) is a large, complex area of bright and dark nebulosity in the constellation Carina, located in the Carina–Sagittarius Arm of the Milky Way galaxy.
SN 1006 was a supernova that is likely the brightest observed stellar event in recorded history, reaching an estimated −7.5 visual magnitude, [3] and exceeding roughly sixteen times the brightness of Venus.
