Among some amateur astronomers, NGC 246 is known as the Pac-Man Nebula because of the arrangement of its central stars and surrounding star field. Among some amateur astronomers, NGC 246 is known as the Pac-Man Nebula because of the arrangement of its central stars and the surrounding star field. NGC 246 is a planetary nebula in the constellation Cetus. NGC 246, nicknamed the Skull Nebula, was discovered by William Herschel in 1785.
NGC 246 (also known as the Skull Nebula or Caldwell 5) is a planetary nebula in the constellation Cetus. These three stars together make NGC 246 the first known planetary nebula with a hierarchical triple star system at its centre.
How far away is the Skull Nebula?
The Skull Nebula, officially known as NGC 246, is located at a distance of about 1 600 light-years in the constellation Cetus (the Whale). This new image of the Skull Nebula shows where NGC 246 is rich or poor in hydrogen (in red) and oxygen (light blue). This image shows the sky around the location of NGC 246, the Skull Nebula, which can be seen in blue in the centre of the image. This map shows the location of the planetary nebula NGC 246, also known as the Totenkopf Nebula, in the constellation Cetus (The Whale).
This video sequence starts with a wide field of the sky region around NGC 246, the Skull Nebula, and approaches the planetary nebula.
Where is the Skull Nebula located?
This video sequence begins with a wide field of the sky region around NGC 246, the Skull Nebula, and closes in on the planetary nebula. The Skull Nebula, officially known as NGC 246, is located about 1600 light years away in the constellation Cetus, also known as the Whale. This new image of the Skull Nebula shows where NGC 246 is rich or poor in hydrogen (in red) and oxygen (light blue). All the data collected can also be used for scientific purposes and will be made available to astronomers through ESO’s Science Archive.
Which eye looks like a nebula?
This astronomical formation is known as the Helix Nebula and is located 700 light years from Earth in the constellation Aquarius. Referring to its appearance like a giant eye in space, another said, “The Helix Nebula is nicknamed the Eye of God or God’s Eye. NASA has released a stunning image of a giant eye-shaped nebula that is one of the brightest and closest to Earth. Two of NASA’s space telescopes have captured a spectacular new photo of the Helix Nebula, a glowing celestial vision that resembles a giant cosmic eye.
NASA has asked space fans to “keep your eyes peeled” as it showcases some of the most popular nebulae on its Instagram account this month.
How old is the Rosette Nebula?
The stars in the energetic cluster, catalogued as NGC 2244, are only a few million years old, while the central cavity in the Rosette Ne bula is about 50 light-years across. The Rosette Nebula has been discovered piece by piece, as it is difficult to observe even with larger telescopes. The Rosette Nebula (also known as Caldwell 4) is an H II region near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. In optical light, the nebula looks like a rosebud, or the “rosette ornament” from ancient times.
