At the time, it was designated simply as a small faint planetary nebula.

Both decided that it was a faint nebula rather than a cluster.

IC 410, a faint nebula, is accompanied by the bright open cluster NGC 1893.

The faint nebula is approximately seven light-years long (with an apparent length of 10 arcminutes), and is 2,700 light-years away from Earth.

As telescopes improved these faint nebulae would be broken into more descriptive scientific classifications such as interstellar clouds, star clusters, and galaxies.

He was the first to describe the shape of the Milky Way and speculate that faint nebulae were distant galaxies.

Another of Thomas Wright's ideas, which is also often attributed to Kant, was that many faint nebulae are actually incredibly distant galaxies.

Q. I have heard that all the stars we can see with the naked eye, except for a few faint nebulae, are part of our own galaxy.

Any faint nebulae seen with the unaided eye are actually part of Earth's home galaxy as well, Mr. Rao said.

It was originally catalogued as a faint nebula.
