Known as Sharpless 2-106, the hourglass-shaped (bipolar) nebula is a stellar nursery made up of glowing gas and light-scattering dust. The material shrouds a natal high-mass star thought to be mostly responsible for the hourglass shape of the nebula due to high-speed winds which eject material from the forming star deep within. Research also indicates that many sub-stellar objects are forming within the cloud and may someday result in a cluster of 50 to 150 stars in this region.

The Crab Nebula (M1) is a supernova remnant and pulsar wind nebula in the constellation of Taurus. At the center of the nebula lies the Crab Pulsar, a neutron star (or spinning ball of neutrons), which emits pulses of radiation from gamma rays to radio waves with a spin rate of 30.2 times per second. The nebula was the first astronomical object identified with a historical supernova explosion. The nebula acts as a source of radiation for studying celestial bodies that occult it.

NGC 7635, also called the Bubble Nebula, is a H II region emission nebula in the constellation Cassiopeia. The "bubble" is created by the stellar wind from a massive hot young central star, the 15 solar masses SAO 20575. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.It was discovered in 1787 by Friedrich Wilhelm Herschel.

NGC 5395 and 5394 , also known as Arp 84, are two interacting galaxies in the constellation Canes Venatici. The larger, NGC 5395, is at a distance 165 million light-years and NGC 5394 is 162 million light-years away. NGC 5394 is thought to have cart wheeled through NGC 5395, instead of a grazing encounter. Arp 84 is also known as the Heron Galaxy. The image shows a few dozen background galaxies.

The Trifid Nebula (M20) is an H II region located in Sagittarius. Its name means 'divided into three lobes'. The object is an unusual combination of an open cluster of stars, an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifid appearance).

M51, the Whirlpool Galaxy, in Canes Venatici is famous for its beautiful spiral structure, was discovered by Messier in October 1773. The M51 system is a spectacular example of interacting galaxies - in this case NGC 5195 is being "ripped apart" by the huge gravitational disturbance of M51, while M51 has in turn undergone huge structural alteration from the gravitational effects of NGC 5195.

Messier 56 (M56) is located about half-way between Beta Cygni (Albireo) and Gamma Lyrae. It is one of the less bright Messier globulars, especially lacking the bright core which most globulars have. M56 was one of Charles Messier's original discoveries; he saw it first on January 23, 1779 and describes it as a "nebula without stars," like most globular clusters. It was first resolved into stars by William Herschel around 1784.
