Big Dipper
The Big Dipper (also known as the Plough) is an asterism consisting of the seven brightest stars of the constellation Ursa Major. Four define a “bowl” or “body” and three define a “handle” or “head”. It is recognized as a distinct grouping in many cultures. The North Star (Polaris), the current northern pole star and the tip of the handle of the Little Dipper, can be located by extending an imaginary line from Big Dipper star Merak (β) through Dubhe (α). This makes it useful in celestial navigation.

Engagement Ring
The Engagement Ring: Through binoculars, the North Star (Polaris) seems to be the brightest on a small ring of stars. Not a constellation or cluster, this asterism looks like a diamond engagement ring on which Polaris shines brightly as the diamond.

Little Dipper
Constellation Ursa Minor is colloquially known in the US as the Little Dipper, because its seven brightest stars seem to form the shape of a dipper (ladle or scoop). The star at the end of the dipper handle is Polaris, the North Star. Polaris can also be found by following a line through two stars in Ursa Major—Alpha and Beta Ursae Majoris—that form the end of the ‘bowl’ of the Big Dipper, for 30 degrees (three upright fists at arms’ length) across the night sky.

Summer Triangle
The Summer Triangle is an asterism involving a triangle drawn on the northern hemisphere’s celestial sphere. Its defining vertices are the stars Altair, Deneb, and Vega, which are the brightest stars in the constellations Aquila, Cygnus, and Lyra, respectively.

Boötes
Boötes has a funny name. Pronounced boh-OH-deez, this constellation’s name means sheepherder, or herdsman. It looks kind of like a kite, or a shoe. Some remember that “Boötes look like a boot” to help pick it out in the sky.

Corona Borealis
Corona Borealis, or “Northern Crown”, is a tiara-shaped, or C-shaped constellation. Its brightest star, called Alphecca, or Gemma, shines like the crown jewel centerpiece of a brilliant celestial tiara. It’s southern counterpart, Corona Australis, or “Southern Crown” lies just south of the ecliptic.

Cygnus
Cygnus is a large constellation, prominent in the Northern Hemisphere. Its name comes from the Greek for “Swan” and can be imagined as a giant, celestial swan, flying overhead, with its wings fully extended. The brightest star in Cygnus is Deneb, which is one of the brightest stars in the sky, and a whopping 800 lightyears away! Deneb is one point of an asterism called the Summer Triangle—three very bright stars that form a large triangle shape prominent in the Northern hemisphere summer skies.

Leo
Leo is a fairly well known constellation, because the plane of the Solar System runs through it. Such constellations are called Zodiac Constellations. Leo has some notable, bright stars, in it to boot. The brightest of these, Regulus is at the bottom of a series of stars arrayed in the form of a sickle, or a backwards question mark. This constellation does look more or less like the side profile of a lion lying on the ground, with its head up.

Lyra
Lyra is a small, but notable constellation. It is host to Vega—the fifth brightest star in the sky (or sixth, counting the Sun). Not far from Vega is Messier object 57—the Ring Nebula, which is perhaps the best known planetary nebula in our sky. Lyra’s name is Greek for lyre—a kind of harp.

Scorpius
Both the plane of the Solar System (called the ecliptic) and the plane of the Milky Way pass through Scorpius—the scorpion. As a result, you can find both the planets of our Solar System (which move along the ecliptic), and many kinds of deep sky objects in this constellation. Scorpius’s brightest star, Antares, is also known as the Heart of the Scorpion, because of it’s reddish hue and location in the chest of the scorpion. Being both red in color, and near the ecliptic, Antares is a rival of sorts to the planet Mars, which is also reddish in color, and occasionally passes through Scorpius. The name Antares means “opposing Mars”.

Ursa Major
Ursa Major, or, the Big Bear, is one of the best known and most well recognized constellations, but you might know it by a different name. Contained within the boundaries of the constellation Ursa Major is the Big Dipper, which is not a true constellation, but an asterism. The Big Dipper is useful for finding both the North Star and the bright star Arcturus. Follow the curve of the handle to “arc to Arcturus” and use to two stars in the dipper opposite the handle to point to the North Star.

Ursa Minor
Ursa Minor, the Little Bear, is much fainter than it’s companion the Big Bear, Ursa Major. Within Ursa Minor is the well known asterism The Little Dipper. The end of the tail of the bear, or the end of the handle of the dipper, is a star called Polaris—the Pole Star, or the North Star. This special star happens to sit at the point where the Earth’s axis of rotation intersects the sky

Virgo
Virgo’s brightest star Spica is found by following the curve of the handle of the Big Dipper (“arc to Arcturus, in Boötes, then spike to Spica”).The rest of the constellation isn’t particularly bright, but Virgo lies along the ecliptic—the plane of the Solar System, so bright planets pass through occasionally.

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.

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.

Coma Berenices
Coma Berenices: “Berenice’s Hair,” a giant Y-shaped open star cluster. It is only 280 lightyears away and appears a bit east of Leo.

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.

Moon
The same side of the Moon always faces Earth because the lunar periods of rotation and revolution are the same. The surface of the moon is covered with impact craters and lava-filled basins. The Moon is about a fourth of Earth’s diameter and is about 30 Earth-diameters 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.

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.

Mizar & Alcor
In the handle of the Big Dipper, Mizar & Alcor (ζ & 80 Ursae Majoris) or the “Horse & Rider” form a naked-eye double star. They are traveling through space together about 80 light-years away from us, separated by about a light-year. However, it is unknown if they are actually gravitationally bound to each other. A telescope splits Mizar itself into two stars, but these both are again doubles, bringing the total in this system to six.

2.1 Meter Telescope and Robo-AO
The 2.1 Meter telescope has an 84″ primary mirror made of Pyrex, that weighs 3,000 lbs. The telescope became operational in 1964—one of the first operational reserach telescopes on the mountain. As part of the National Optical Astronomy Observatory (NOAO) for many decades, it is an important part of the history of the mountain, and has made many important contributions to astronomical research. Despite its significant role within the National Observatory, by 2015 the time came to pass the telescope on to new tenants, so NOAO could focus its efforts on its newer, more advanced telescopes. The Robo-AO team stepped in, and installed their state-of-the-art robotic adaptive optics system on the 2.1 Meter. Adaptive optics allows telescopes to nearly eliminate the distorting effects of the atmosphere, greatly increasing the resolution of the telescope. Thanks to its new tenants, suite of instruments, and the dark skies of Kitt Peak, the 2.1-meter continues to make important contributions to astronomical research.

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.

Arizona Radio Observatory 12 Meter Telescope
Originally, a 36 foot (11 meter) radio telescope resided in this dome. Built in 1967, the 36 Foot Telescope, as it was known, was a part of the National Radio Astronomy Observatory (NRAO). In 1984, it was replaced with a slightly larger dish, and the name was changed to the 12 Meter Telescope.

In 2000, the NRAO passed control of the telescope to the University of Arizona. The University of Arizona had been operating the Submillimeter Telescope (SMT) located on Mount Graham since 1992. When it took over operations of the 12m, it created the Arizona Radio Observatory (ARO) which now runs both telescopes.

In 2013, the telescope was replaced with ESO’s ALMA prototype antenna. The new dish is the same size, but has a much better surface accuracy (thereby permitting use at shorter wavelengths), and a more precise mount with better pointing accuracy. The 12m Radio Telescope is used to study molecules in space through the use of molecular spectroscopy at millimeter wavelengths. Many of the molecules that have been discovered in the interstellar medium were discovered by the 12m.

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.

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.

The RCT
The Robotically-Controlled Telescope (RCT) is a 1.3-meter telescope on a German equatorial mount. The RCT occupies the dome across from the Kitt Peak Visitor Center. The long building attached to the RCT dome is the Kitt Peak administration building. The RCT name originally stood for Remotely-Controlled Telescope, and it served the KPNO user community almost 30 years before being closed in 1995. The telescope was originally proposed by the Space Sciences Division at KPNO as the Remote Control Telescope System (RCTS) to be an engineering research platform for the development of remote control protocols for envisioned orbital telescopes. In later years, the telescope was used to test out various instrumentation that was later used on the larger 2.1-meter and 4-meter telescopes of Kitt Peak. In 2004 The RCT Consortium began operating the telescope as its new tenants. Today, the telescope is mostly used either remotely, with observers operating the telescope via the internet, or robotically, with the telescope opening and observing automatically, using its programming to determine what to observe based on scheduling and observing conditions.
