Chasing Carina
http://apod.nasa.gov/apod/
This picture is of the Carina Nebula this is also known as to some astronomers as NGC 3372. This nebula is over 300 light-years big. In this picture we can see in upper right of this beautiful picture that there is much more than the more than it's neighbor the Orion Nebula. Tthe Carina Nebula is our galaxy's largest star-forming regions which is also home to very large young stars. In this mass of young stars we can see the still variable Eta Carinae, this star has well over 100 times the mass of our star, also known as the Sun. This Nebulae is also very close to the middle of the 10 degree length of field this also is connected with NGC 3576 and NGC 3603. In this picture we can also see what is commonly known as the Running Chicken Nebula in the upper part of this beautify detailed picture.

James Edward Keeler
James Edward Keeler was born September 10, 1857 and died in August 12, 1900. He was a very successful American astronomer. He married and had two children. In 1899 he won the Henry Draper Medal. This medal was awarded to U.S. Astronomers by the U.S. National Academy of Science. He died in 1900 at the age of 42, his ashes were interred in a crypt along the base of a 31 inch Keeler Memorial telescope. This telescope is at the Allegheny Observatory.
Before he was appointed the director of the University of Pittsburgh’s Allegheny Observatory, which happened in 1891, he worked at the Lick Observatory, starting in 1888. At Lick Observatory on 7 January he was the first person to observe the Encke Gap, the gap in Saturn’s rings by using a 36 inch refractor. This was named after him and also when the Voyager discovered a second major gap in the A ring they named it the Keeler Gap in James Keeler’s honor. He did more work with Saturn’s rings, he noticed different Doppler shifts and the reasons for so he came up with was, that they had different rates of orbit. This confirmed James Clerk Maxwell theory that Saturn’s rings are made up of countless small objects. Each which orbit around at the objects own rate. James Keeler made this observation with a spectrograph which attached to a 13 inch Fizclark refracting telescope. He did these observations at Allegheny Observatory. Because of James’ many amazing discoveries with the reflecting telescope, he made showed how important the use of large optical reflecting telescopes are. Even after his death he was still discovering new objects. After his death his fellow colleagues had his photographs of nebulae and clusters. They did this in a special volume that consisted of Lick Observatory publications. In 1899 and 1900 he also discovered two asteroids. Although one of his asteroids where sadly lost, and it only took about 100 years later for Astronomers to find it, but his other one was name after him, asteroid 2261 Keeler. Crater on Mars and the Moon where also named in James’ honor.

WISE Infrared Andromeda
This is a beautiful picture of what appears to be a swirling bunch of stars maybe a Galaxy. In the description of the picture we find out that this was taken using infrared light from the Galaxy of Andromeda Galaxy or M31. Other wise known as the princess. The young stars are yellow and red and the bluish ones would be the older stars. The picture is helped to make easier to see with false coloring, because with infrared light we can not see it with our eyes so scientists have to color is in using fake colors. This Galaxy is so large that it is over twice the diameter of the MIlky Way.
With this picture we are more able to see more stars and things that may be behind this Galaxy because of the Infrared light.

Night Launch of the Space Shuttle Endeavour
This picture is an amazing picture of the shuttle launch. This is shuttle, Endeavour, lifted off February 8th. From the Launch pad 39A at Kennedy Space Center, Fl. This shuttle is bound for the International Space Station. This is the last night launch for the USA. In this picture we can see the exhaust plume eject from the shuttle. This is a beautiful picture and i hope to see it in real live one day. The shuttle against the night sky make the shuttle pop.

Stardust in Perseus
In this picture we can see many beautiful stars slightly covered with a dust. This cosmic dust is a gas that covers the sky near the constellation Perseus, also known as hero. In this picture we can also see NGC 1333, this nebula is only around 1,000 light-years away. Next to this nebula we can see again another dust, this time a reddish glow. This is hydrogen gas created by energetic jets also from stars winds, the process from how they are created. Along the edges of these gases and clouds there are a lot of newly formed stars, that is how the gas got there, from the stars when they formed. This picture helps explain how stars are formed by giving us the gas that is produced from there formation and how far away they are from this gas.

Dust Storm on Mars
In this picture we can see the marvelous red planet of Mars. The background is all black and the focus is only on mars. In the description we read that it is spring on the northern hemisphere on this planet. Mars is unlike Earth in the fact that in spring on Mars there are not flowers and blooming life but there are dust storms. We can see the dust storm in this picture by the brownish swath of dust, which we can see in the top of this picture. It is possible for astronomers to get good pictures of mars like this because Mars is in opposition and very close to the earth. The dust storm we can see most clearly is the large dark region on this picture, also known as Mare Acidalium, which is under the polar cap, or the white part of the red planet. THis pitcure helps astronomers better understand seasons on other planets.
