Kitt Peak Nightly Observing Program

Splendors of the Universe on YOUR Night!

Many pictures are links to larger versions.

M51 Whirlpool Galaxy

M51, the Whirlpool Galaxy, gets its name from its bright and prominent spiral arms. It lies at a distance of 23 million light-years away. It also has a smaller, companion galaxy (NGC 5195). The two galaxies are one of the best examples of interacting galaxies.    

M82 Cigar Galaxy

M82, the “Cigar Galaxy” is an edge-on spiral galaxy, 12 million light-years away, and perhaps 37,000 light-years across. There are vast gas clouds in this galaxy, where stars are being born at an incredible rate.    

M3

M3 is a globular cluster with a half of a million stars. It orbits the core of our Milky Way Galaxy almost perpendicular to the galactic disk. It is currently 33,900 light-years away, and approaching our Solar System at 100 miles per second.

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.

M37 Salt & Pepper Cluster

each group got to see one open cluster. Those in the first telescope session got to see M 37 while those in the second session got to see M 44. 

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.   

M44 The Beehive

each group got to see one open cluster. Those in the first telescope session got to see M 37 while those in the second session got to see M 44. 

M44, the “Beehive Cluster,” and also known as “Praesepe,” is a large, bright, diffuse open star cluster containing about 400 stars. It lies fairly close, at a distance of under 600 light-years.

NGC 2392 (Eskimo Nebula)

This was shown during our first telescope session, but unfortunately we didn’t have time during our second. 

NGC 2392: The “Eskimo Nebula.” A round cloud of gas ejected by a dying star. Since this sort of object always appears round, William Hershel named them “planetary nebulae” (he discovered this one in 1787).

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.

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.

Castor (α Gem)

Castor (α Geminorum) is a multiple star in the constellation Gemini, the twins. Through the telescope, a close pair of bright white stars and a more distant red dwarf companion are visible, but these are each spectroscopic binaries, making Castor a six-star system. Castor is about 50 light-years away. The bright components orbit each other with a period of about 450 years.
