January Tonight’s Sky January Tonight’s Sky Constellations The winter sky is filled with brilliant stars. Orion the hunter is the centerpiece, striding into the night sky with a belt of three stars. Above Orion lies a five-sided figure that forms Auriga, the charioteer, who was associated with goats. Its brightest star is Capella, which is actually a pair of giant yellow stars. Auriga balances on a horn of Taurus the bull. In Greek mythology, Taurus was seen as the god Zeus in disguise. His eye is orange Aldebaran, a red giant star nearing the end of its life. A number of the stars that form the bull’s V-shaped head are part of a star cluster called the Hyades. The bull’s shoulder is marked by the distinctive Pleiades star cluster, also called the Seven Sisters. The cluster contains more than 250 stars, but only six or seven are visible to the naked eye. This view of the Pleiades from the Palomar Observatory shows the brightest stars surrounded by a dusty cloud. The dust reflects the blue light of these hot stars. At the tip of Taurus’s horn lies the Crab Nebula. The Crab is the remains of a star that exploded as a supernova, observed by Chinese, Japanese, and Arab astronomers in 1054. Telescopes on the ground and in space have observed different forms of light given off by the Crab Nebula. Different wavelengths of visible and invisible light reveal details of the supernova remnant. Combining information from different wavelengths helps us better understand the expanding cloud of glowing gas and the spinning neutron star that remains at its core. Celestial wonders await you in tonight’s sky. - 1 - .

Messier Objects
Messier Objects From the Stocker Astroscience Center at Florida International University Miami Florida The Messier Project Main contributors: • Daniel Puentes • Steven Revesz • Bobby Martinez Charles Messier • Gabriel Salazar • Riya Gandhi • Dr. James Webb – Director, Stocker Astroscience center • All images reduced and combined using MIRA image processing software. (Mirametrics) What are Messier Objects? • Messier objects are a list of astronomical sources compiled by Charles Messier, an 18th and early 19th century astronomer. He created a list of distracting objects to avoid while comet hunting. This list now contains over 110 objects, many of which are the most famous astronomical bodies known. The list contains planetary nebula, star clusters, and other galaxies. - Bobby Martinez The Telescope The telescope used to take these images is an Astronomical Consultants and Equipment (ACE) 24- inch (0.61-meter) Ritchey-Chretien reflecting telescope. It has a focal ratio of F6.2 and is supported on a structure independent of the building that houses it. It is equipped with a Finger Lakes 1kx1k CCD camera cooled to -30o C at the Cassegrain focus. It is equipped with dual filter wheels, the first containing UBVRI scientific filters and the second RGBL color filters. Messier 1 Found 6,500 light years away in the constellation of Taurus, the Crab Nebula (known as M1) is a supernova remnant. The original supernova that formed the crab nebula was observed by Chinese, Japanese and Arab astronomers in 1054 AD as an incredibly bright “Guest star” which was visible for over twenty-two months. The supernova that produced the Crab Nebula is thought to have been an evolved star roughly ten times more massive than the Sun.

Not one star in the image can be seen by the naked eye. 4. Color of star reﬂects its surface temperature. Eagle Nebula. M 16 1. Messier 16 is a conspicuous region of active star formation, appearing in the constellation Serpens Cauda. This giant cloud of interstellar gas and dust is commonly known as the Eagle Nebula, and has already created a cluster of young stars. The nebula is also referred to the Star Queen Nebula and as IC 4703; the cluster is NGC 6611. With an overall visual magnitude of 6.4, and an apparent diameter of 7', the Eagle Nebula's star cluster is best seen with low power telescopes. The brightest star in the cluster has an apparent magnitude of +8.24, easily visible with good binoculars. A 4" scope reveals about 20 stars in an uneven background of fainter stars and nebulosity; three nebulous concentrations can be glimpsed under good conditions. Under very good conditions, suggestions of dark obscuring matter can be seen to the north of the cluster. In an 8" telescope at low power, M 16 is an impressive object. The nebula extends much farther out, to a diameter of over 30'. It is ﬁlled with dark regions and globules, including a peculiar dark column and a luminous rim around the cluster.

A Basic Requirement for Studying the Heavens Is Determining Where In
Abasic requirement for studying the heavens is determining where in the sky things are. To specify sky positions, astronomers have developed several coordinate systems. Each uses a coordinate grid projected on to the celestial sphere, in analogy to the geographic coordinate system used on the surface of the Earth. The coordinate systems differ only in their choice of the fundamental plane, which divides the sky into two equal hemispheres along a great circle (the fundamental plane of the geographic system is the Earth's equator) . Each coordinate system is named for its choice of fundamental plane. The equatorial coordinate system is probably the most widely used celestial coordinate system. It is also the one most closely related to the geographic coordinate system, because they use the same fun damental plane and the same poles. The projection of the Earth's equator onto the celestial sphere is called the celestial equator. Similarly, projecting the geographic poles on to the celest ial sphere defines the north and south celestial poles. However, there is an important difference between the equatorial and geographic coordinate systems: the geographic system is fixed to the Earth; it rotates as the Earth does . The equatorial system is fixed to the stars, so it appears to rotate across the sky with the stars, but of course it's really the Earth rotating under the fixed sky. The latitudinal (latitude-like) angle of the equatorial system is called declination (Dec for short) . It measures the angle of an object above or below the celestial equator. The longitud inal angle is called the right ascension (RA for short).

Eagle Nebula Star Formation Region
Eagle Nebula Star Formation Region AST 303: Chapter 17 1 The Formation of Stars (2) • A cloud of gas and dust must collapse if stars are to be formed. • The self-gravity of the cloud will tend to cause it to collapse. • Radiation pressure from nearby hot stars may do the same. • The passage of a shock wave from a nearby supernova blast or some other source (such as galactic shock waves) may do the same. – Note: The “sonic boom” of a jet plane is an example of a shock wave. • When two clouds collide, they may cause each other to collapse.

Universe Discovery Guides: December — Crab Nebula
National Aeronautics and Space Administration UNIVERSE DISCOVERY GUIDES December CRAB NEBULA In this Hubble close-up of the Crab Nebula, various chemical elements have been detected in the expanding gas, including hydrogen (orange), nitrogen (red), sulfur (pink), and oxygen (green). Some of these elements are newly generated during the life and the explosive death of the star and now blasted back into space. These chemical elements will eventually be incorporated into new stars and planets.

How about the iron in your blood or the oxygen in the air we breathe? You may have seen the table of the elements — these are the atoms which are the building blocks that make up everything we see, including us. Some of those atoms combine to make molecules, like water (consisting of hydrogen and oxygen) and sugars (consisting of carbon, hydrogen and oxygen) — ingredients for supporting life. The number of protons in the atom’s nucleus determine which element it is. For example, hydrogen has one proton; helium has two protons; carbon has six protons; iron has twenty-six protons.

Astronomy in the Park 2014 Schedule
Astronomy in the Park 2014 Schedule Members of the Stockton Astronomical Society will volunteer to setup their telescopes for the public at S.J. County Oak Grove Regional Park on the first Saturday after the New Moon. During the months of April through October the Nature Center will also be open with indoor astronomy activities. If the sky is cloudy or there is bad weather the telescopes may not be available. During the months of November through March the Nature Center will not be open. Also, if the sky is not clear the event may be canceled and we will try again the next month. • S.J. County charges a Parking Fee of $6.00 per vehicle but the Nature Center and telescope viewing is free. • SAS volunteers can contact James Rexroth for free parking passes. • Indoor astronomy themed activities for kids (both big & small) will be in the Nature Center. • Telescope viewing starts after Sunset, the Moon will be visible in the telescopes from the start. As the sky darkens more objects become visible. Darker and clearer sky is better for viewing. • Every month we will feature a different deep sky object. We will point one of our large telescopes at this object during the last hour of the evening. These objects are dim and fuzzy and are best seen in large aperture telescopes. • To view objects it may be necessary to stand on a ladder or step stool that will be next to the telescope. For more information call: James Rexroth S.J. County Oak Grove Regional Park (Nature Center) (209) 953-8814 Doug Christensen Stockton Astronomical Society (209) 462-0798
