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. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.

NGC 6357 is a diffuse nebula near NGC 6334 in the constellation Scorpius. The nebula contains many proto-stars shielded by dark disks of gas, and young stars wrapped in expanding “cocoons”.

This nebula was given the name War and Peace Nebula by the Midcourse Space Experiment scientists because of its appearance. They said that in infrared images the bright, western part resembles a dove, while the eastern part looks like a skull.

  • The Eagle Nebula is part of a diffuse emission nebula, or H II region. This region of active current star formation is about 7000 light-years distant. Several spires of gas that can be seen coming off the nebula.
  • The descriptive names reflect impressions of the shape of the central pillar rising from the southeast into the central luminous area

The CARINA nebula, also known as the Eta Carinae nebula, is an area of both bight and dark nebulae.

It is found in the Carina constellation and is thought to be located between 6 500 and 10 000 light years from Earth. It is one of the largest diffuse nebulae in our skies and is even larger (and brighter) than the famous Orion nebula. It is home to the brightest star in the Milky Way Galaxy- WR 25.

Some objects contained within this nebula are:

  • Eta Carinae: hypergiant star- currently the largest star that can be studied due to its location.
  • Homunculus Nebula: believed to have been ejected in an enormous outburst in 1841.
  • Keyhole Nebula: portion of the nebula that is dark. It doesn’t have its own NGC designation.
  • Mystic Mountain: dust-gas pillar found by the Hubble Space Telescope.

Just wondering, do you know what the closest nebula to our solar system is?

‘Nebula’ has a weird definition. The best answer, I think, is the gorgeous Orion nebula.

Orion is a diffuse nebula that is so close (~1350 light years away) that you can see with the naked eye. It’s situated below Orion’s belt and looks something like this to the naked eye:

The ORION nebula is a nebula located in the Milky Way Galaxy, in the constellation Orion. It is a diffuse nebula, which means that it has no defined borders. It is one of the brightest nebulae visible to the naked eye and is the closest region of massive star formation to Earth!

Astronomers have been able to identify many steps in the star formation process by observing the Orion Nebula. Neither Ptolemy or Galileo noted the Orion Nebula in their notes from observing the sky, so it is believed to think that the Stars have become brighter since then, allowing it to be visible to naked eye viewers.

The nebula is part of a larger nebula known as the Orion Molecular Cloud Complex. This extends through the Orion constellation and contains Barnard’s loop, the Horsehead nebula, the Flame nebula, and some other smaller ones!

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated south of Orion’s Belt. It is one of the brightest nebulae, and is visible to the naked eye. M42 is located at a distance of 1,270±76 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across.

This is the Orion Nebula. The Orion Nebula is a diffuse nebula that is situated in the famous Orion’s Belt (Constellation Orion).

One of the brightest known nebulae, it is visible to the naked eye if you’re in areas where there isn’t significant light pollution.

Classified as Messier 42, NGC 1976. Roughly 1,344 lightyears away and approximately 24 light years across, it’s truly one of the most impressive known nebulae.
