Kitt Peak Nightly Observing Program

Splendors of the Universe on YOUR Night!

Many pictures are links to larger versions.

M8 Lagoon Nebula

M8: The “Lagoon Nebula.” A huge cloud of gas and dust beside an open cluster of stars (NGC 6530). The Lagoon is a stellar nursery, 4,100 lightyears away, towards the galactic core.

M5

M5 is a bright, large globular cluster, 25,000 light-years away. It is 13 billion years old, 165 light-years in diameter, and may contain as many as half of a million stars.

Clouds

Kitt Peak has an abundance of clear nights, but that doesn’t mean the clouds never move in. We hope you’ll join us again another time when our dark mountain skies are at their best!

Milky Way

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!

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.

M11 Wild Duck Cluster

M11 is an open star cluster also known as the “Wild Duck Cluster,” due to its purported prominant V-shape, reminiscent of a flock of wild ducks in flight. This open cluster is 20 light-years in diameter and 6,200 light-years away.

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.

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.

Saturn

Saturn, the second-largest planet in the Solar System, is known for its showy but thin rings made of ice chunks as small as dust and as large as buildings. Its largest moon, Titan, has an atmosphere and hydrocarbon lakes; at least 61 smaller moons orbit Saturn.

The Galilean Moons

Jupiter’s four largest moons are known as the Galilean Moons, named for Galileo, who was the first astronomer to study them in depth and determine that they were orbiting Jupiter. Their individual names are Io, Europa, Ganymede, and Callisto—in orbital order from closest to Jupiter to furthest out. Ganymede is the largest of these four moons, and is the largest moon in our Solar System. Io, the closest of these four moons to Jupiter, is the most volcanic world in our Solar System. Io is home to hundreds of active volcanos. Its neighbor, and the next furthest from Jupiter of the four, Europa, is a dramatic contrast to Io with its icy surface. Europa is covered by water, which is frozen solid at the surface. The furthest our of the four, Callisto is a fascinating world in our Solar System because it is so utterly geologically dead. Without weather, moonquakes, volcanism, or any other surface-altering processes, Callisto’s surface is billions of years old—a kind of record of the history of the Solar System.

We got to see quite a bit before the clouds rolled in, thank you for your patience!
