The very familiar Horsehead Nebula (aka Barnard 33) is ~1,375 light-years from Earth and is one of the most identifiable nebulae because of its resemblance to a horse's head. It's a small dark nebula in the constellation Orion. The super-bright star to the left of the Horsehead is Alnitak, the...

The Soul Nebula (aka IC 1848) is an emission nebula about 6500 light-years from Earth. It's a star-forming region that includes several open clusters of stars and large evacuated bubbles formed by the winds of young massive stars. This image is the result of 6-2/3 hours of exposure time (50...

The Heart Nebula (aka IC 1805). It's an emission nebula ~7500 light years away, shaped like a heart consisting of glowing ionized hydrogen gas and darker dust lanes. The nebula's intense red output and shape are driven by radiation emanating from a small group of stars near the nebula's...

The Pleiades (aka “The Seven Sisters” and M45) is an open star cluster - a group of stars that were all born around the same time from a gigantic cloud of gas and dust. It contains more than 800 middle-aged, hot stars. The cluster is dominated by hot blue stars that formed within the last 100...

The Andromeda galaxy (M31), with its two satellite galaxies M110 (bottom-right) and M32 (fuzzy ball just above and left of the core). M31 is the closest major galaxy to the Milky Way. While it is barely visible to the naked eye under very dark skies, it spans a surprisingly large swath of the...

The "Veil Nebula" is a cloud of heated and ionized gas and dust left over from a massive supernova that occurred 10,000 years ago when a star 20 times more massive than the Sun and ~2,100 light-years away ended its life in a spectacular explosion. The event would have appeared brighter than...
