A nebula is a large cloud of dust and gas, floating through the galaxy. Nebulae
can be formed from the gases left over from dead or dying stars, but they can
also be formed from interstellar gas and dust, from which new stars will form.
Some objects may be large enough to be seen by the naked eye, but are too dim to actually see. The Rosette Nebula is one of these; at 1.3° wide, it is nearly three times the size of the Full Moon in the sky!
It takes a camera to bring it out of hiding; but once it's out, it's an amazing view!
Not all nebulae make an impression for being big and bright. The Dumbbell Nebula is a great example of how a small, but bright, nebula can stand out among a sea of stars!
Embedded within the disk of the Milky Way in the night sky, this nebula shines like a jewel among the 'salt-and-pepper' of the stars around it!
New processing techniques applied to old data. With a minimal setup, and less than an hour of integration time, it's possible to get a stunning image of the Orion Nebula!
The Ring Nebula is one of the brightest nebulae in the night sky, popping out to the eye or camera with very little magnification needed! Despite its popularity, it is one of the smaller nebulae out there, and can be a difficult object to reveal detail without great magnification.
Nonetheless, the Ring Nebula is a stunning example of what gets left over after a low-mass star dies!
The Horsehead Nebula and its surrounding region is one of the iconic objects of the winter sky! Part of the massive Orion Complex, this star forming region and its surrounding nebulae lie on Orion's Belt, near to the famous Orion Nebula.
This magnificent region of sky is one of the brightest to any camera, and is always a favourite of astrophotographers!
The Cone Nebula and Christmas Tree Cluster make up a beautiful region of sky in Monoceros, and are part of a much larger star-forming region. The mixture of colours make these objects a favourite for imaging!
The California Nebula is a beautiful band of red gas that streaks across the night sky! Though it's too small to be seen by the naked eye, it is a rather large object, and stretches out to cover a larger patch of sky than the Full Moon occupies!
The Crescent Nebula is an emission nebula that is the result of huge shockwaves of colliding gas in interstellar space. Although extremely long exposures of the region reveal a huge region of nebulosity, the nebula stands out due to its relatively bright crescent shape.
The West Veil Nebula, or the Witch's Broom, is part of a vast nebular complex that spans degrees of sky; a remnant of a supernova that exploded some 8,000 years ago, sending its old stellar material out into our galaxy!
The Cygnus Wall is one of the most dynamic regions of the North American Nebula; a nebula in the shape of its namesake continent! Spanning nearly 3° of sky, this nebula is one of the "unseen" gems of the night sky!
The Bubble Nebula is perfectly named for its bubble shape; the result of a hot young star blowing its surrounding material away with an intense stellar wind. It makes an excellent pair with the open cluster Messier 52 nearby, itself an easy object in binoculars and small telescopes!
The Crab Nebula is a supernova remnant, leftover from a Type II supernova that was observed by Chinese astronomers in 1054 AD! Due to its proximity, it is a favourite for astronomers both amateur and professional alike!
The Eagle Nebula is a star-forming region 7,000 light-years away, and is home to the famed Pillars of Creation! Occupying a region of sky larger than the Full Moon, this nebula is thousands of light-years in diameter with a central star cluster which is only a couple million years old!
