M42 The Orion Nebula
(SECOND GROUP ONLY)
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.
(FIRST GROUP ONLY)
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.
(SECOND GROUP ONLY)
Though dim, M79 is just about the only globular cluster easily seen in the Northern Hemisphere Winter sky. It lies 41,000 light-years away and orbits our galaxy further out than our sun does—unusual since most globular clusters are congregated towards the center of the galaxy.
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.
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.
Mars, the red planet, has a thin carbon dioxide atmosphere, clouds, dust storms, and polar caps made of dry ice. Images of dry riverbeds from orbiting spacecraft show us that liquid water once flowed on the Martian surface.
Uranus, the seventh planet from the Sun, was discovered by Sir William Herschel in 1781. It has a dark set of rings and at least 27 moons. Uranus’s axis of rotation is almost 90 degrees from those of the other planets, as if Uranus has been tipped onto its side.
