This belt is considered special because it is where the sun, the moon, and the planets all move. The word zodiac means “circle of figures” or “circle of life”. As the earth revolves around the sun, different parts of the sky become visible. Each month, one of the 12 constellations show up above the horizon in the east and disappears below the horizon in the west. If you are born under a particular sign, the constellation it is named for can’t be seen at night. Instead, the sun is passing through it around that time of year making it a daytime constellation that you can’t see!

Spring Constellations Leo
Night Sky 101: Spring Constellations Leo Leo, the lion, is very recognizable by the head of the lion, which looks like a backwards question mark, and is commonly known as “the sickle.” Regulus, Leo’s brightest star, is also easy to pick out in most lights. The constellation is best seen in April and May, but rises after the Spring Equinox in March. Within the constellation, there are several spiral galaxies: M65, M66, M95, and M96. It is possible to fit M65 and M66 into the same view on a low powered telescope. In Greek mythology, Leo was the Nemean lion, who was completely impervious to bronze, steel and any kind of metal. As part of his 12 labors, Hercules was charged to fight the lion and killed him Photo Credit: Starry Night by strangling him. Hercules took the lion’s pelt as a prize and Leo, the lion, was placed in the stars to commemorate their fight. Virgo Virgo is best seen in the late spring and early summer, usually May to June. The bright star Arcturus, in the constellation Boötes, lines up with the Virgo’s brightest star Spica, which makes it easy to find. Within the constellation is the Virgo Galaxy Cluster, which is a conglomerate of thousands of unnamed galaxies. These galaxies are about 65 million light years away, and usually only appear as smudges in a telescope. Virgo, the maiden, is also known as Persephone, or the daughter of the Demeter. Hades, god of the Un- derworld, fell in love with Virgo and took her to the Underworld. -

Astronomy for Kids - Leo
Astronomy for Kids - Leo The Lion Leo is another companion to Orion in our night sky. You can easily find Leo any Leo Map time that Orion is visible by looking East of the Great Hunter. Although Leo is not as large as Orion, it's distinctive shape makes it very easy to pick out. If you click on the link for the map of Leo on the right, you will notice that the outline of the lion's head and the triangle formed by the stars in the lion's hindquarters are two very distinctive shapes that make this constellation very easy to spot. A map of Leo. Regulus - the Heart of the Lion The largest and brightest star in Leo is Regulus. This large blue star shines brightly as the heart of the lion. Although not a giant star, Regulus is still over five times as large as our Sun. A small telescope will show you that Regulus is part of what is called a "binary system". Binary stars are stars that have one or more companions that orbit around the largest star in the group, much like the planets orbit around our Sun. Find Out More About Leo Chris Dolan's Leo Page Chris Dolan's Leo page has lots of technical information about the stars that make up Leo Richard Dibon-Smith's Leo Page Richard Dibon-Smith's Leo page has a very good explanation of the mythology behind Gemini as well as an excellent reference to its stars and other interesting celestial companions.

NSF's National Optical Infrared Astronomy Research Laboratory
NSF’s National Optical Infrared Astronomy Research Laboratory and Planetary Science Tod R. Lauer (NOIRLab) [email protected] (520) 861-4618 John Blakeslee (Gemini / NOIRLab) NSF’s National Optical Infrared Astronomy Research Laboratory (NOIRLab) is a new organization that consolidates NSF’s National Optical Astronomy Observatory (NOAO), the Gemini Observatory, and the operation of the Rubin Observatory into a unified system for providing the US research community with frontier observational facilities and data. NOIRLab will also be tasked with providing the community with access to the US extremely large telescope (ELT) projects now in development: the Giant Magellan Telescope and the Thirty Meter Telescope, if the NSF invests in construction and/or operations of one or both of these telescopes Historically, NOAO and Gemini have enthusiastically supported planetary science research, and fully expect to continue to do so over the coming decade. The Rubin Observatory will soon begin operations with its Legacy Survey of Space and Time (LSST), which will provide a deep census of small bodies throughout the solar system. The ELTs will be built around high- performance adaptive optics fed imaging and spectroscopy, which will be available for detailed study of all solar system objects, and will support strong programs in exo-planet research. The Decade Ahead We write to the Planetary Science and Astrobiology Decadal Survey with the simple goal of requesting that the survey consider us within the constellation of facilities available for supporting initiatives in planetary science and astrobiology over the coming decade. Overall, we see NOIRLab supporting leading-edge planetary science research with all of its facilities, and would enjoy working with the planetary science community to realize this ambition. -

Its symbol is (Unicode ♑). Capricornus is one of the 88 modern constellations, and was also one of the 48 constellations listed by the 2nd century astronomer Ptolemy. Under its modern boundaries it is bordered by Aquila, Sagittarius, Microscopium, Piscis Austrinus, and Aquarius. The constellation is located in an area of sky called the Sea or the Water, consisting of many water-related constellations such as Aquarius, Pisces and Eridanus.

CONSTELLATION BOÖTES, the HERDSMAN Boötes Is the Cultivator Or Ploughman Who Drives the Bears, Ursa Major and Ursa Minor Around the Pole Star Polaris
CONSTELLATION BOÖTES, THE HERDSMAN Boötes is the cultivator or Ploughman who drives the Bears, Ursa Major and Ursa Minor around the Pole Star Polaris. The bears, tied to the Polar Axis, are pulling a plough behind them, tilling the heavenly fields "in order that the rotations of the heavens should never cease". It is said that Boötes invented the plough to enable mankind to better till the ground and as such, perhaps, immortalizes the transition from a nomadic life to settled agriculture in the ancient world. This pleased Ceres, the Goddess of Agriculture, so much that she asked Jupiter to place Boötes amongst the stars as a token of gratitude. Boötes was first catalogued by the Greek astronomer Ptolemy in the 2nd century and is home to Arcturus, the third individual brightest star in the night sky, after Sirius in Canis Major and Canopus in Carina constellation. It is a constellation of large extent, stretching from Draco to Virgo, nearly 50° in declination, and 30° in right ascension, and contains 85 naked-eye stars according to Argelander. The constellation exhibits better than most constellations the character assigned to it. One can readily picture to one's self the figure of a Herdsman with upraised arm driving the Greater Bear before him. FACTS, LOCATION & MAP • The neighbouring constellations are Canes Venatici, Coma Berenices, Corona Borealis, Draco, Hercules, Serpens Caput, Virgo, and Ursa Major. • Boötes has 10 stars with known planets and does not contain any Messier objects. • The brightest star in the constellation is Arcturus, Alpha Boötis, which is also the third brightest star in the night sky. -
