Hubble's Nebula (NGC 2261), Emily Vyn

Hubble's Variable Nebula is a mixed deep celestial object. It is a reflection-emission nebula. The majority of it can be found in the constellation Monoceros, called known as Unicorn. It has been estimated that Hubble's Nebula is 3000 lightyears away, give or take 1500 lightyears. It is a very large nebula, as its angular size is 3'x1' arc minutes. Its linear size is 2.6 light-years.

This nebula has an interesting shape. It resembles a pacman shape, and is surrounded by haze. It is hard to get a clear picture of what this nebula looks like, as it is so far away. It is a wonder how many and various the objects are that fill our vast universe.
