Splendors of the Universe on YOUR Night!

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.    

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.

M15

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.

Ecliptic

The ecliptic is a path in the sky, forming a great circle around the Earth, which the Sun and other planets of the Solar System move along. It is formed where the plane of the Solar System intersects with the Earth’s sky.

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.

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!

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.

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.

Uranus

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.

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.

Albireo (β Cyg)

Named long before anyone knew it was more than one star, Albireo (β Cygni) comprises of a set of stars marking the beak of Cygnus, the swan. Through a telescope, we see two components shining in pale, but noticeably contrasting colors: orange and blue. The difference in color is due to the stars’ difference in temperature of over 9000°C! The brighter orange component, Albireo A, is actually a true binary system, though we can’t resolve two stars in the telescope. The fainter blue component, Albireo B, may be only passing by, and not gravitationally interacting with Albireo A at all. Albireo is about 430 light-years away.

3.5-Meter WIYN Telescope

The WIYN Observatory is owned and operated by the WIYN Consortium, which consists of the University of Wisconsin, Indiana University, National Optical Astronomy Observatory (NOAO), the University of Missouri, and Purdue University. This partnership between public and private universities and NOAO was the first of its kind. The telescope incorporates many technological breakthroughs including active optics hardware on the back of the primary mirror, which shapes the mirror perfectly, ensuring the telescope is focused precisely. The small, lightweight dome is well ventilated to follow nighttime ambient temperature. Instruments attached to the telescope allow WIYN to gather data and capture vivid astronomical images routinely of sub-arc second quality. The total moving weight of the WIYN telescope and its instruments is 35 tons. WIYN has earned a reputation in particular for its excellent image quality that is now available over a wider field than ever before through the addition of the One Degree Imager optical camera.

Kitt Peak VLBA Dish

The Very Long Baseline Array (VLBA) is a part of the Long Baseline Observatory (LBO). It consists of a single radio telescope made up of ten 25 meter dishes. The ten dishes are spread across the United States, from Hawaii to the Virgin Islands. One dish is located on Kitt Peak: The LBO Kitt Peak Station. Kitt Peak Station, along with the other dishes, work in unison to point at the same targets at the same time. The data is recorded and later combined. By spreading the dishes out over such a great distance, instead of building them all in the same place, a much higher resolution is gained.

Mayall 4-Meter Telescope

The Mayall 4 Meter Telescope was, at the time it was built, one of the largest telescopes in the world. Today, its mirror—which weighs 15 tons—is relatively small next to the mirrors of the world’s largest telescopes. Completed in the mid-’70s, the telescope is housed in an 18-story tall dome, which is designed to withstand hurricane force winds. A blue equatorial horseshoe mount helps the telescope point and track the sky. A new instrument called DESI (Dark Energy Spectroscopic Instrument) will soon be installed on the 4-meter. Once installed, DESI will take spectra of millions of the most distant galaxies and quasars, which astronomers will use to study the effect of dark energy on the expansion of the universe.

The Mayall 4 Meter is named for Nicholas U. Mayall, a former director of Kitt Peak National Observatory who oversaw the building of the telescope.

McMath-Pierce Solar Telescope

The Mc Math Pierce Solar Telescope is actually 3 telescopes-in-one. It was, at the time of its completion in the 1960s, the largest solar telescope in the world. It will remain the largest until the completion of the Daniel K. Inouye Solar Telescope (DKIST) in 2018. The Solar Telescope building looks like a large number 7 rotated onto its side. The vertical tower holds up 3 flat mirrors, which reflect sunlight down the diagonal shaft—a tunnel which extends 200 feet to the ground, and another 300 feet below ground, into the mountain. At the bottom of this tunnel are the three curved primary mirrors, which reflect the light of the Sun back up to about ground level, where the Sun comes into focus in the observing room.

SARA 0.9-Meter Telescope

SARA stands for Southeastern Association for Research in Astronomy. Formed in 1989, SARA sought to form a mutually beneficial association of institutions of higher education in the southeastern United States which have relatively small departments of astronomy and physics. At the time, a 36″ telescope on Kitt Peak was being decommissioned by the National Observatory. The Observatory planned to award the telescope to new tenants who showed they could use the telescope well. SARA’s proposal for use of the telescope was selected out of about 30. Today, SARA operates the 0.9 meter telescope of Kitt Peak, as well as a 0.6 meter telescope at Cerro Tololo in Chile. Both telescopes can, and are mostly used remotely.
