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.
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.
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.
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.
Comets were once harbingers of doom—unpredictable and terrifying celestial sights. We now know that comets are balls of ice, rock, and dust tens of kilometers across. As comets approach the Sun, the ices vaporize and sometimes form long, spectacular tails.
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.
