Silver Star

myth behind it interesting and endearing, a tale of two lovers not unlike Romeo and Juliet. It is one of the brightest constellations and is known as the Hunter, it is also one of the most well known constellations. It contains 2 of the 10 brightest stars in the sky and a collection of nebulae. The myth behind it is of Greek Origin. The infant Orion was given as a gift to a poor shepard who had unknowingly shown kindness and hospitality to the two Gods Zeus and Poseidon and in return they gifted him

Milky Way Shows That Stars Are On the Move The Draw of the Milky Way Stargazing is often thought to be something lovers would do on a date or something of a hobby. Astronomers and scientists of all kinds make their careers out of it every day. The beauty of the Milky Way is one that is otherworldly. This is what makes it so fascinating. The Map of the Milky Way Therefore it is no surprise that scientists put together a map of the Milky Way for observational purposes. However recently, a press

1. I've chosen the constellation "Draco." I chose this one because it was the constellation that my mother always talked about when I was little. She'd tell me stories about it's stars and she'd always let me stay up late to look at it. Draco is the 8th largest constellation and has 9 stars, the brightest of which is Gamma Draconis. It belongs to the Ursa Major family. 2. One of the myths about Draco, and my favorite, is the Greek one where Draco represents the dragon, Ladon, who was charged with

Introduction
 Using astronomical instruments astronomers have been able to learn many properties about distant objects including other stars and our own Sun. How to Determine the Properties of Distant Objects Composition Because of Earth’s atmosphere only optical and radio spectroscopy can be used on Earth’s surface. They both utilize longer wavelengths and in different ways can be used to help us determine certain characteristics of distant objects. Obviously with optical spectroscopy we

1. We are all made out of stars. You, the canyon, the river… everything is made from the remnants of stars that have exploded and sent matter out into the universe to coalesce and become… Earth, us, the rocks, the trees, the everything. Any element heavier than hydrogen, like the calcium, carbon, nitrogen, oxygen, and approximately 60 other basic ingredients that make a human, originated in the stars. 2. The Grand Canyon has some of the darkest skies left on the planet. When you are here, you can

The main difference between them is that a typical Seyfert AGN releases as much energy in the visual bands as all the stars of its (∼ 1011 L ) host galaxy, while a typical QSO is by a factor of ∼ 100 times brighter than the stars of its host galaxy. Seyferts and QSOs, however, are not the only sub-classes of the AGN family. Below, I briefly summarize the most important characteristics of the basic AGN sub-classes: i Seyfert

STARS – THE BIRTH OF STARS A star is a luminous sphere of plasma held together by its own gravity. It is a burning ball of gas Fig 1.1 Nebulae (A stellar nursery) (Chandra, Hubble, and Spitzer image NGC 1952) Stars are born or formed in Nebulae or Nebulas are huge interstellar clouds, in inter-galactic space, of dust and gas (mostly hydrogen H2) There is an abundance of such stellar nurseries in the arms of Spiral Galaxies. The birth of star occurs many atoms of light elements are compressed

properties of stars. The method was improved in 1913 by American astronomer Henry Norris-Russell. Today the diagram is known as a Hertzsprung-Russell diagram, or simply an H-R diagram. This diagram is very significant tool for studying the evolution of stars. A H-R diagram plots a star’s luminosity against its temperature or color. The vertical axis is the stars luminosity relative to the sun (1 L0 is the luminosity of our sun) and the horizontal axis plots the temperature or color of a star. The highest

incredible the universe really is. Wolf-Rayet Stars – These massive stars are evolved and have completely lost their outer hydrogen, so they are fusing helium and heavy elements in their core. http://www.universetoday.com/24736/wolf-rayet-star/

Solar Mass Main Sequence Star Once its 10 billion years of burning comes to an end, the hydrogen that it has been using as a fuel source has, for the most part, depleted. The center of the star begins to increase in size as the production of helium increases and an inner core of helium starts to grow. The helium does not burn at these temperatures so the burning is moved out to higher layers. This inner core begins to shrink under the force of gravity and while the star is extremely hot, it is
