M31 Andromeda Galaxy

The Andromeda Galaxy is our nearest major galactic neighbor. It is a spiral galaxy 2,500,000 light-years away, and has a diameter of 220,000 light-years. This galaxy contains as much material as 1.5 trillion suns.    

NGC 253 Sculptor Galaxy

Ngc 253: The “Silver Dollar Galaxy”. A lumpy, dusty, nearly-edge-on spiral galaxy just a bit smaller than the Milky Way. At least 75 billion solar masses, eleven million lightyears from here. It was discovered by Caroline Hershel in 1783.

M15

M15 is a distant globular cluster, 33,000 light-years away. It has 100,000 stars, and is one of the oldest known globular clusters, having formed about 12 billion years ago.

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!

M37 Salt & Pepper Cluster

M37, the “Salt and Pepper Cluster” is one of three bright open star clusters in the constellation Auriga. It is the brightest and richest of the three. It lies about 4,500 light-years away, contains about 150 stars, has a diameter of about 25 light-years, and is 450 million years old.   

NGC 457 The Owl Cluster

NGC 457 is an open star cluster in the constellation Cassiopeia. It was discovered by William Herschel in 1787, and lies over 7,900 light-years away from the Sun. It has an estimated age of 21 million years. The cluster is sometimes referred by amateur astronomers as the Owl Cluster or ET Cluster. The cluster features a rich field of about 150 stars of magnitudes 12-15.    

M1 Crab Nebula

M1: The Crab Nebula. The explosion that created this nebula was seen by Chinese astronomers in 1054 A.D. This explosion was bright enough to be seen in the daytime for almost a month. The nebula is 11 lightyears in diameter and is expanding at the rate of 1,500 km per second.

M57 Ring Nebula

M57: The Ring Nebula. This remnant of a dead star looks exactly as it’s name says – a ring or doughnut shape cloud of gas. The nebula is about 2.6 lightyears across and lies about 2,300 lightyears away.

M76 Little Dumbbell Nebula

M76: “The Little Dumbell”. This complex bubble of gas is the cloud of material ejected by a dying star. This ghostly glow has a fairly bright rectangular component with very dim outer loops. M76 is estimated to be more than 2,500 light years away; which means the bubble of gas is more about 1.2 light years across.

Neptune

Neptune, eighth planet from the Sun, is a blue “gas giant” about 4 Earth-diameters across. At least 14 moons orbit Neptune. Galileo accidentally observed Neptune in 1612 and 1613 but did not realize it differed from the stars—its true discovery would wait until 1846.

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.

Venus

Venus, the second planet, is the brightest natural object in the sky other than the Sun and Moon and is often erroneously called the “morning star” or “evening star.” It is completely wrapped in sulfuric acid clouds and its surface is hot enough to melt lead.

Albireo (β Cyg)

Named long before anyone knew it was more than one star, Albireo (β Cygni) comprises of a set of stars marking the beak of Cygnus, the swan. Through a telescope, we see two components shining in pale, but noticeably contrasting colors: orange and blue. The difference in color is due to the stars’ difference in temperature of over 9000°C! The brighter orange component, Albireo A, is actually a true binary system, though we can’t resolve two stars in the telescope. The fainter blue component, Albireo B, may be only passing by, and not gravitationally interacting with Albireo A at all. Albireo is about 430 light-years away.

Mu Cephei (μ Cep)

Mu Cephei (μ Cephei), also known as Herschels Garnet Star, is a red supergiant star in the constellation Cepheus. It is one of the largest and most luminous stars known in the Milky Way. It appears garnet red and is given the spectral class of M2 Ia. Since 1943, the spectrum of this star has served as one of the stable anchor points by which other stars are classified.

Thank you for joining me this evening! I hope you enojoyed our dark skies, and I hope we will see you again soon!!
