Kitt Peak Nightly Observing Program

Splendors of the Universe on YOUR Night!

M104 Sombrero Galaxy

M104: A spiral galaxy like the Milky Way, nicknamed the “Sombrero Galaxy” because the lane of dust in the disk looks like the brim of such a hat. It is about 50,000 lightyears across and about 29 million lightyears away.

M13 Hercules Globular

M13, the “Great Globular Cluster in Hercules” was first discovered by Edmund Halley in 1714, and later catalogued by Charles Messier in 1764. It contains 300,000 stars, and is 22,000 light-years away. Light would need over a century to traverse its diameter.

Meteors

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.

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.

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.

Algieba (γ Leo)

Algieba (γ Leonis) is a binary star in the mane of Leo, the lion. These two golden-yellow giant stars are about 23 and 10 times the diameter of the Sun, and are about 130 light-years away. Their orbital period is over 500 years. In 2009, a giant planet was found orbiting one of these stars.
