Central Coast Astronomy Virtual Star Party May 15Th 7Pm Pacific
Central Coast Astronomy Virtual Star Party May 15th 7pm Pacific Welcome to our Virtual Star Gazing session! We’ll be focusing on objects you can see with binoculars or a small telescope, so after our session, you can simply walk outside, look up, and understand what you’re looking at. CCAS President Aurora Lipper and astronomer Kent Wallace will bring you a virtual “tour of the night sky” where you can discover, learn, and ask questions as we go along! All you need is an internet connection. You can use an iPad, laptop, computer or cell phone. When 7pm on Saturday night rolls around, click the link on our website to join our class. CentralCoastAstronomy.org/stargaze Before our session starts: Step 1: Download your free map of the night sky: SkyMaps.com They have it available for Northern and Southern hemispheres. Step 2: Print out this document and use it to take notes during our time on Saturday. This document highlights the objects we will focus on in our session together.

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. -

Whirlpools and Pinwheels on the Sky
Whirlpools and pinwheels on the sky Domingos Soares Galaxies exist in many different forms and count by, at least, the hundreds of billions, according to estimations made from the observations of the Hubble Space Telescope. Among all of them, there are no doubts that the most spectacular are the so-called \spiral galaxies". Our own galaxy, the Milky Way galaxy, is a member of that family. Spiral galaxies are so named because of the distinctive aspect they present to the observer, namely, of a spiral-shaped structure similar to a whirlpool or a pinwheel. They are also called \disk galaxies" because the galactic material | stars, gas and interstellar dust | is distributed in the shape of a \thick" disk. The stars constitute the main constituents of galaxies, at least with respect to their visual appearance. They emit the major part of the visible light of a galaxy, be it a spiral or not. The typical visual aspect of spiral galaxies is due to the structures that astronomers call \spiral arms". The most bright stars of a galaxy are those that delineate the arms. These, however, contribute little to the total mass of the galaxy, but due to their extraordinary brightness they are the most noticeable on a visual inspection. The spiral galaxy disks rotate. And this is typical in those galaxies: the galactic material spins around the disk center, which is called \galactic center". But the rotation is not like the spin of a rigid disk, like, for example, a CD, in which all the points make a full turn in the same time interval. -

GALAXIES WHAT ARE the DEEP SKY OBJECTS? •Deep-Sky Objects Are Astronomical Objects Other Than Individual Stars and Solar System Objects (Sun, Moon, Planets, Comets)
GALAXIES WHAT ARE THE DEEP SKY OBJECTS? •Deep-sky objects are astronomical objects other than individual stars and solar system objects (Sun, Moon, planets, comets). TYPES OF DEEP SKY OBJECTS •Nebulae •Clusters •Galaxies CHARLES MESSIER • Known for the Messier catalogue of galaxies, nebulae and star clusters M1 to M110 • He was a French astronomer who lived in the 18th century. • He was a comet hunter and the purpose of the catalogue was to record the sky objects that looked as comets but were not comets because they would not move in the sky. UNITS TO MEASURE DISTANCE • A Light-year is the distance that light travels in a year with a speed of approximately 300,000 kilometers per second • Closest star to the Sun is Proxima Centauri at 4.37 light years. • A Parsec is the equal to about 3.26 light years GALAXIES • A galaxy is an enormous collection of gas, dust and billions of stars held together by gravity. One galaxy can have hundreds of billions of stars and be as large as 200,000 light years across. • Galaxy is derived from the Greek galaxias meaning "milky", a reference to the Milky Way. • Many galaxies are believed to have black holes at their active center. The Milky Way's central black hole, known as Sagittarius A, has a mass four million times that of our Sun. GALAXIES FACTS • There are potentially more than 170 billion galaxies in the observable universe. Some, called dwarf galaxies, are very small with about 10 million stars, while others are huge containing an estimated 100 trillion stars. -

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). -

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.
