44. Exploring The Meaning Of Stars There are 88 recognized constellations. Many are associated with myths. constellationsare fun, and help us locate stars and galaxies in the sky. http://www.msnucleus.org/membership/html/k-6/uc/universe/1/ucu1_3a.html

Universe Cycle - Universe (1) Post Lab OBJECTIVES: Exploring the meaning of stars. Discovering constellations in the night sky. VOCABULARY: constellation galaxy star MATERIALS: Glow in Dark Night Sky Book by Clint Hatchett (Random House) Internet Students explore the patterns of stars. BACKGROUND: Students have learned that stars make their own energy, which is how they produce light. Although the stars are still in the sky during the day, the light of the Sun prevents us from seeing them. Only on a clear night can we see the stars. Cloud cover can also prevent the light from the stars from reaching our eyes. The stars are long distances from us on Earth. Large, far away stars seem smaller than they really are. Our Solar System is in a grouping of stars called the Milky Way Galaxy. Most of the stars we see at night are from the Milky Way. However, it is often difficult to tell a star from the Milky Way from another galaxy in the sky. Far away galaxies may also appear as single points of light. Early people grouped many of the bright objects in the sky as constellations. A constellation is a group of stars that, viewed from Earth, appear to form a regular pattern. There are 88 recognized constellations. Many are associated with myths. Constellations are fun, and help us locate stars and galaxies in the sky. However, they are not a scientific grouping, because they are mixtures of stars and galaxies, that may be near or far objects.

Malin's micrographs Miller's twilights Fujii's constellations Anglo-Australian Observatory David Malin Images, microscope to telescope, seen from pole to pole.... David Malin Images (DMI) is a source of high quality photographs of stars, galaxies and nebulae taken with some of the world's finest optical telescopes and by talented photographers using ordinary cameras. The images cover most of the sky on all angular scales, from the nearby constellations to the Milky Way and far distant galaxies. Many of these pictures have been made by David Malin , mainly from plates taken with the telescopes of the Anglo-Australian Observatory . These pictures focus on stars and star-forming regions, globular clusters and the endless variety of galaxies. Other pictures, of star trails and constellations, were made with more modest equipment, both by David Malin and his associates David Miller and Akira Fujii. The pictures are divided according to their source and often according to subject matter as well. The individual pages below take you on a tour of the distant universe with professional telescopes. David Miller's images are beautiful views of the nearest star at the beginning and end of the day and the moon, set in the Australian landscape. In between are the constellations, the star colours vividly captured by Akira Fujii. A new series of intriguing and attractive images are photomicrographs of crystals. These are images of science but are presented as abstract art. All the images on these pages are available as high resolution digital files as well as prints.

Cassiopeia - The Queen In ancient mythology Cassiopeia was a proud queen, wife of King Cepheus and mother of the princess Andromeda , today she shares the heavens with these constellations. A prominent feature in the night sky in the northern hemisphere, from the UK and much of Europe and North America the constellation is circumpolar and its stars never set. October is a particularly good time to spot Cassiopeia as it appears almost overhead. The constellation is composed of five stars, similar in brightness to those of the Plough, and forms the shape of a W or M. A line drawn from the star Mizar located in the Plough through Polaris, the pole star, and extended for about the same distance on the far side will bring you to Cassiopeia. Since Cassiopeia and the Plough revolve around Polaris on opposite sides, when one constellation is riding high in the sky the other is closest to the horizon. Arcing through Cassiopeia is the backbone of the night, the Milky Way. You'll need to be in the country away from menacing light pollution to be able to see this faint band of light which represents another arm of our home galaxy. Not surprisingly Cassiopeia is rich in knots of star clusters and the ghostly webs of nebulae. A glorious slight is to recline in a deck-chair with a pair of binoculars and sweep this part of the sky. Binoculars are by far the best piece of equipment to reveal the myriad of stars since they allow a wide field of view. The brightest star cluster in Cassiopeia is NGC-457 often called the 'Owl cluster' owing to its shape (NGC stands for New General Catalogue, a catalogue of star clusters, galaxies and nebulae). Located close to

Continued Astrophysics Theoretical Astrophysics is the discipline that seeks to explain the phenomena observed by astronomers in physical terms. With this purpose, theoretical astrophysicists create and evaluate models to reproduce and predict the observations. Theoretical astrophysicists use a wide variety of tools which include analytical models (for example, polytropes to approximate the behaviors of a star) and computational numerical simulations. Each has some advantages. Analytical models of a process are generally better for giving you insight into the heart of what is going on. Numerical models can reveal the existence of phenomenon and effects that you would not otherwise see.

CONSTELLATIONS AND STARS There are about 48 old constellations. Today astronomers recognize 88 (44 in each hemisphere) dividing all of the entire sky. THE GREAT BEAR AND THE SEVEN STARS THE LITTLE BEAR AND POLARIS: Five major constellations are always visible above the horizon from our latitudes: Ursa Minor, Ursa Major, Cassiopeia, Cepheus and Draco. They all revolve once in 24 hours around the North Star and stars in these are known as Circumpolar stars. Ursa Minor or the Little Bear is well known for being the host of Polaris, positioned very close to the celestial north pole. Actually the Polaris revolves in radius of 1 degree about the North celestial pole. Polaris is the brightest star in the Ursa Minor. It is part of 7 well known stars similar to Big Dipper. The handle in it curves towards the bowl unlike Big Dipper. CASSIOPEIA Cassiopeia lies on the other side of the pole from Ursa Major, almost directly opposite the Big Dipper. One can sees the seven stars with naked eyes. Sometimes people visualize it as part of a Crown of the Egyptian queen Cassiopeia, other people see it as an inclined chair or throne. CEPHEUS NEXT TO CASSIOPEIA is her husband the king Cepheus, known for some of the well-studied variable stars. Cepheus forms a shape resembling the cap of a clown. Its wedge corner is very close to Polaris and is one of the circumpolar stars. The brightest star in this constellation is called Aldemarin, meaning the arm. It stays close to his queen.

Front page The List Generator Help for the Messier Gallery If you can't find the explanation you nead here, then either look in a book somewhere (which is the best thing to do), or send me a mail. Select a helptopic Other names Type Constellation Number of stars Inclination Star magnitude Consentration Spesific brightness Position angle Apparent magnitude Right Ascension Declination Distance Notes Other names There are many catalog other than NGC and Messier's catalog. There are also common names out there for various objects. Some are named after the discoverer, other for their shape. I don't expect you to know or remember any of the other names, but if you wanted to know... You can atleast learn something from them, and that's why I made this page (after beeing a catalog with pictures). Type The following types are in use: OC : Open Cluster Open clusters are collections of stars in the Milky Way. They may appear bright, because most of them are near, but most of them are very faint. The OCs in Messier's catalog though are mostly bright. The stars in an OC are formed together in giant clouds like the Orion Nebula (M42), and then drift apart slightly. Many OCs therefore have BN's assosiated with them. The diffenrence from normal stars is that the stars in an OC stick together because of the gravity between them. GC : Galactic Cluster Galactic clusters can be seen as miniature galaxies, allthough some of them can be quite large. In my opinion there is no real gap between the smallest galaxies and the largest GCs. They are actually
