Splendors of the Universe on YOUR Night!

Hercules

Hercules is named for the famous hero of Greek mythology by the same name. It’s one of the larger constellations, but its stars are of only moderate brightness. The Keystone is a well known trapezoid-shaped asterism (association of stars that are not an official constellation) within Hercules. This constellation is host to M13 (Messier 13), a globular star cluster. Otherwise known as the Hercules Globular Cluster, M13 is home to 300,000 stars, and is just over 22,000 light-years away.

Sagittarius

Sagittarius, the archer, is often depicted as a centaur wielding a bow and arrow. Within Sagittarius, is a fairly recognizable teapot shape known to many simply as The Teapot (the teapot is not a true constellation, but an asterism). The plane of the Milky Way passes through Sagittarius, and in fact, the center of the Milky Way is in the direction of the westernmost edge of this constellation—just above the spout of The Teapot. With the plane of the Milky Way passing through, there are a plethora of deep sky objects to be found in Sagittarius.

M17 Swan Nebula

M17, also known as the “Swan Nebula,” or the “Omega Nebula” is a vast cloud of gas—mostly hydrogen, in which clumps of gas are contracting to make new stars. The nebula is 15 light-years across, and 5,500 light-years away.

M13 Hercules Globular

M13, the “Great Globular Cluster in Hercules” was first discovered by Edmund Halley in 1714, and later catalogued by Charles Messier in 1764. It contains 300,000 stars, and is 22,000 light-years away. Light would need over a century to traverse its diameter.

Milky Way

That clumpy band of light is evidence that we live in a disk-shaped galaxy. Its pale glow is light from about 200 billion suns!

Satellites

Human technology! There are almost 500 of these in Low Earth Orbit (we can’t see the higher ones). We see these little “moving stars” because they reflect sunlight.

M11 Wild Duck Cluster

M11 is an open star cluster also known as the “Wild Duck Cluster,” due to its purported prominant V-shape, reminiscent of a flock of wild ducks in flight. This open cluster is 20 light-years in diameter and 6,200 light-years away.   

Jupiter

Jupiter is the largest planet in the Solar System, a “gas giant” 11 Earth-diameters across. Its atmosphere contains the Great Red Spot, a long-lived storm 2-3 times the size of the Earth. The 4 large Galilean satellites and at least 63 smaller moons orbit Jupiter.

Saturn

Saturn, the second-largest planet in the Solar System, is known for its showy but thin rings made of ice chunks as small as dust and as large as buildings. Its largest moon, Titan, has an atmosphere and hydrocarbon lakes; at least 61 smaller moons orbit Saturn.
