The Orion Nebula (Messier 42) is the nearest star-forming region to Earth. It is located in the Orion Constellation, just below Orion's Belt.

Within the Orion Nebula lies the Orion Bar, a sharp, diagonal, ridge-like feature of gas and dust. The Orion Bar is essentially the edge of an astronomically large bubble carved out by some of the ...

The Orion Nebula is classified as an emission nebula — a cosmic cloud of dust and gas that shines by emitting its own light. Recent studies place its distance at about 1,300 light-years.

Rather, it's an emission nebula about 1,000 light-years from Earth. To the right of the image is the rather iconic Horsehead Nebula, which really does resemble the head of a horse. It's a little ...

Located in the constellation Orion, this emission nebula is a vibrant star-forming region, visible to the naked eye. Its striking colors and bright stars make it a popular target.

Sagittarius A, the intense radio source at the centre of our Galaxy, has no counterpart in the Andromeda Nebula although the structure of the nucleus is otherwise similar. The bright supernova of ...

Many scientific terms are very specific, but the term nebula is, well, nebulous. In a very generic sense, it simply means a fuzzy thing. But there are a wide variety of astronomi ...
