Centaurus - The Centaur While August often brings warm summer evenings, the long hours of daylight mean the night is short and, along with summer haze, the seeing (which describe show good observing conditions are) is never as crisp as an autumnal or winter evenings. However, its the opposite situation for southern hemisphere observers. The southern hemisphere is now well in the grip of winter, and the long cold winter evenings are ideal for astronomers. One prominent constellation which holds a plethora of interesting objects is Centaurus , the mythical half-man half-horse constellation. Although never visible from mid northern latitudes, it is a common sight for those who live in Australia or New Zealand. Perhaps the most famous object in Centaurus is Omega Centauri , a splendid globular cluster. Globular cluster are compact roughly spherical clusters of relatively old stars which circle our galaxy. Although observers in the northern hemisphere can see M13, a globular cluster in the constellation of Hercules, Omega Centauri appears larger and brighter.

If it's not below the horizon, Spica is the brightest star of the constellation Virgo the Maiden. Although Virgo is the second largest constellation in the sky, the rest of its stars are faint. Yet don't be surprised if you often see a bright visiting planet nearby. Virgo was long ago recognized for its importance, since it contains the Sun on the day of the Autumn Equinox. Spica lies nearly on the path the Sun follows across the sky, which is called the ecliptic. You won't see this constellation in the early autumn, for then Virgo lies in the daytime sky.

What is Midnight Culmination Skylore Only the most imaginative can see a bear in the area of the Big Dipper. There are many star-patterns that look like dippers, triangles, or squares in the sky. There are very few that actually resemble bears or people. Yet constellations were named to honor particular figures in ancient stories, not because the star pattern actually looked like the figure being honored. It took imagination to invent them a long time ago, and it takes imagination to see them now. The "handles" of the dippers represent the "tails" of the bears on ancient star mapseven though modern bears don't have long tails! The Big Bear was regarded as a bear before Homer, and an ancient Greek story explains why the Big and Little Bears have such long tails.

Canes Venatici is surrounded by Ursa Maioris to the north, to the east and Coma Berenices to the south (between RA=12h 10m and RA=14h 10m, DECL=+53 deg and DECL=+28 deg). This constellation was introduced 1690 by Johannes Hevelius in his Firmamentum Sobiescianum (see here his drawing (312 kB)). It belongs to the Ursa Maioris constellation family Characteristic for this region of the sky is the high amount of galaxies. Stars and other objects The double alpha CVn , also known as Cor Caroli (meaning "The Heart of Carles"; this name was given to the star by Edmund Halley in honor of Charles II of England), is a blue-white star of 2.9 mag. The companion is a 5 mag star, which can easily be resolved by small telescopes. With a magnitude of about 6 the globular cluster is still among the brightest of its class in the sky. It appears as a hazy patch in binoculars. Small scopes show a softly glowing lightball. To resolve individual stars telescopes with an aperture of 100mm and more are needed.

A downloadable MS Word version of the package OVERVIEW Perhaps the most basic astronomical skill is finding one's way around the night sky. In this activity students will learn the relative locations of several prominent constellations and will learn to identify several stars within those constellations. OBJECTIVES Students will describe the meaning of the term "constellation". Given a diagram of the night sky, students will identify several well known stars and constellations. STATE STANDARDS THE LIGO STAR CHART All of the stars used in our galaxy model are parts of constellations (or star patterns) that are very easy to observe in the night sky from almost anywhere in the northern hemisphere. No telescope is necessary but the sky should be dark. This activity will show you how to locate several features of the night sky. The Big Dipper is the easiest group of stars to identify and can point you in the direction of other interesting areas of the sky. Once you have located the Big Dipper you can use it to find the North Star. Simply imagine connecting Merak and Dubhe with a line and continuing until you reach a medium-bright star.

SEARCH: Hubble Space Telescope advertisement An Eye on the Sky By Maia Weinstock Staff Writer posted: 07:00 am ET 20 July 2000 The Two-Micron All Sky Survey, or 2MASS for short, has returned a flood of data from the skies, including images of millions of stars and galaxies. In fact, the most recent release of 2MASS data covers almost half of the sky and unleashes the most eye-catching near-infrared images to date. SPACE.com proudly presents some of the most interesting and spectacular of this latest batch. The Tarantula Nebula is a faint patch of light located some 160,000 light-years away from Earth in the Large Magellenic Cloud, the nearest galaxy to our native Milky Way galaxy. This is the only nebula outside the Milky Way that can be seen with the naked eye. At the core of the nebula lies a dense clump of hot stars, which until recently were thought to be one massive star. More Stories Half the Heavens: 1.9 Million Night Sky Images Online Scientists say this galaxy, dubbed NGC 891, is very similar to our own Milky Way galaxy. Though we can't see its complete form due to its oblique angle relative to Earth, researchers have shown that the galaxy is rather thin - a likely characteristic shared by the Milky Way. We also know that the galaxy's disk is composed of dust and light from supergiant stars, and is located about 30 million light-years away. The Flame Nebula, also known as the Christmas Tree Nebula, is an area of gas and dust located in the constellation Orion. Scientists say that this dense stellar cluster contains a great many young stars and disks of accreting material, which may be sites of planet formation. This cluster is thought to be less than one million years old.

Constellation Report This weekend we move on to the constellation Ursa Major - The Great Bear . Best known as the " Big Dipper ", Ursa Major is the true name of this constellation. The Big Dipper is what astronomers refer to as an asterism. An asterism is a named grouping of stars which is not officially recognized as a constellation. This is such a well known constellation. In fact, it is probably familiar to and findable by more people than any other constellation. This is a good thing, since two of it's stars, "Merak and Dubhe" are known as the pointer stars. Pointers to Polaris, the " North-Star ". Once you learn these stars, you'll always know your directions at night. To find Polaris (and hence, north) start at Merak and draw a line through Dubhe and you'll arrive at Polaris. Another reason for familiarity with Ursa Major is simply that Ursa Major is home to some of the most beautiful and most amazing deep sky objects known. Many of these are easily viewed in amateur telescopes and will be covered below. The Big Dipper (The Plough in Britain), marks the hindquarters and tail of the Great Bear. The stars, in order right to left are Dubhe, Merak, Phecda, Megrez, Alioth, Mizar, and Alkaid.

The story goes that he climbed a mountain to prepare for his death. When the end came, he ascended into the heavens, where remarkably, he recovered his strength. He was assigned to a new job, to carry the sun high into the sky in the summer. Orion is indeed located in the Northern day sky during the summer months, its presence blotted out by glare of the sun. But as winter approached, the hunter grew tired, and passed the responsibly over to his son. The lazy son shouldered his responsibilities poorly, and barely managed to bring the sun over the horizon, bringing cold winter days. His father meanwhile, rests in the winter night sky, gaining strength to resume his role in the summer. Pleiades: The Seven Sisters, Les Sept Soeurs, Oot-kwa-tah (Iroquois)

NEWS GALLERY DISCOVERIES FUN ... Frequently Asked Questions What are constellations? The entire sky (half of which is above the horizon at any moment) is divided into 88 constellations. The constellations and their borders have nothing to do with science. The stars in a particular constellation are not necessarily related to one another, nor are they even near each other in space. The constellations recognized by astronomers in the northern sky come from ancient Greek and Roman mythological star-pictures. The southern constellations were named by the first Western mariners to explore southern waters. Other cultures have their own constellation patterns, which do not necessarily match "classical" ones. Constellations cover much too broad an area of space to be imaged by the Hubble Space Telescope (HST), and there really is no reason for HST to photograph constellation patterns even if it could be done. Has Hubble found planets around other stars? Astronomers believe that there is little chance of finding new planets in our own solar system, and the Hubble Space Telescope (HST) has not been involved in any searches. However, the search for planets around other stars is very active, and HST is involved. Not even HST has directly seen planets around other stars, but it can detect indirect evidence, as described on our Web site.

This shift of the starry curtain became official with the change of seasons; summer gave way to autumn on September 23. The air will become cooler, leaves are changing color, but the stars of summer linger on for just a little while longer. After dusk in early October go out and look to the top of the sky. You'll see three bright stars forming the Summer Triangle, the seasons' dominant asterism. The brightest star, at the upper right as you face south, is Vega, which is part of the constellation Lyra "the Lyre." Vega is a white hot star located 26 light-years away. From Vega, direct your eyes slowly to the east. The first bright star you'll find is Deneb, the second corner of the Triangle and the tail of Cygnus "the Swan." Cygnus is also known as the Northern Cross. Looking down to the south you'll find Altair, the last star of the Triangle. Altair is part of the head of Aquila "the Eagle." It takes a little more practice and imagination to see the eagle.

The Structure of the Galaxy Activity: The student will map various celestial objects and determine the structure and center of the Milky Way. Science Standards: Nature of Science and Scientific Models (Conceptual) Objectives: The student will observe that distribution of different objects in the sky. The student will infer the shape of the galaxy. The student will infer the direction of the galactic center. Materials: Overhead transparencies of all-sky constellation map (one per group) Different color overhead markers Photocopies of galactic object tables overhead projector and screen Introduction: In the 18th century, astronomers Thomas Wright and William Hershel conducted meticulous sky surveys which indicated that the number of stars in all directions were essentially equal (with respect to distance). From that observation, they inferred that the Sun was at the center of the Universe. Today we know that stars come in different colors, compositions, and ages. By looking at the distribution of different types of stars, we can easily see that there is a plane of new, young, and active stars that surround us. There are also old globular clusters surrounding the galactic center near Sagittarius. Galaxies far beyond the Milky Way are visible in every direction except near the galactic center where they are obscured by galactic dust. Directions: 1. Using transparencies, different groups of students place marks in constellations that have the objects listed in the tables.
