It does not have visible light of its own, that lite is provided by the shine of the stars in it and or around it.
The Tarantula Nebula, also known as 30 Doradus, is one of the largest and most active star-forming regions in our nearby universe. It is located in the Large Magellanic Cloud galaxy, around 160,000 light years away from Earth. The Tarantula Nebula is roughly 1,000 light years in diameter.
One possibility is The Helix Nebula [See Link] or NGC 7293, it is a large planetary nebula located in the constellation of Aquarius at a distance of approximately 700 light years from us.
Because nebula, like galaxies, do not have a defining edge, it is difficult to determine the exact size but an estimate is the closest you'll get.However, in this case, the difference is large enough.The Tarantula Nebula is about 15 times larger than the Carina Nebula.Tarantula ~ 1,000 light years acrossCarina ~ 65 light years across.
The nearest supernova, or more correctly supernova remnant is the Vela [See Link]. It occurred around 11 - 12,000 years ago. Not only is it the oldest, but it is also the closest at about 800 light years.
If the Helix Nebula was an ocean, our Sun would be like a grain of sand. Nebulas are so huge that it takes light thousands of years to cross one, and light is the fastest thing we know of.
The Orion nebula is part of our own galaxy (the Milky Way). The Orion nebula is about 1500 light-years away from us. Our galaxy is about 100000 light-years across.

Considering the distance to the Cats Eye Nebula is only 3,300 light years away, it is going to be within our own Milky Way Galaxy.
M57, the "Ring Nebula", is in our own Milky Way galaxy, about 2300 light years away.
Emission nebula glow and reflection nebula reflect the light form other stars
The biggest known nebula is Tarantula nebula stands 160,000 light years from us. its wide is 650 light years (1 light years = 10 trillion km)
The Egg Nebula is about 3000 light-years from us.
Depending on the type of nebula, they can range from a light year across to over a 100 light years in diameter.
The dark clouds in space are called absorption nebulas or dark nebulas. An absorption nebula is a cloud of gas and dust which blocks light from the regions of space behind it. As light from space reaches an absorption nebula it is absorbed by it and does not pass through. Absorption nebulas do not create their own light. It is hard to find an absorption nebula unless it is silhouetted against much brighter region of space.
No, a nebula is only a few light-years across while a galaxy is thousands of light-years across.
The Trifid Nebula is about 5,200 light years away from Earth.
