M42 The Orion Nebula
M42, the Orion Nebula is a region of star formation about 1,300 light-years away—the closest to our Solar System. It is roughly 30 light-years across, and contains enough material to make 2,000 stars the size of our sun.
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.
Quick streaks of light in the sky called meteors, shooting stars, or falling stars are not stars at all: they are small bits of rock or iron that heat up, glow, and vaporize upon entering the Earth’s atmosphere. When the Earth encounters a clump of many of these particles, we see a meteor shower lasting hours or days.
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!
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.
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.
NGC 7662 Blue Snowball
NGC 7662: A planetary nebula nicknamed the “Blue Snowball.” It is a round cloud thrown off by a dying star, expanded to 1.6 lightyears in diameter. The expanding hot gas would have fried any planets orbiting the star.
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.
