M87: Elliptical Galaxy with Jet
This picture shows a lot of stars, that are not really stars but more like spiral galaxies it is described as majestic winding arms of little stars, or gas, and made by dust rotate in a flat disk like a bulging galactic nucleus swirl. on the other hand these elliptical galaxies seem to be very much like each other. They all are lacking the gas and the dust necessary to form new stars and they are randomly swarming older stars in the area this is what form the ellipsoidal or oblong shape. Still other galaxies are also able to be seen in this picture like the large Virgo Cluster that we can see also called NGC 4478 that is in the center and also NGC 4476 which is close to the right edge.

Calm, Cresent Moon, and Venus
This picture show the Moon and Venus and how they formed a beautiful close pair in the west after sunset which is this picture, this also shows a scene enjoyed by a skygazer and many more all over the world. The view of this conjunction is from the beautiful skis of from Sweden, at the lake Vallentuna that appears to be very calm and that also lies in the front of the sunset with lots of still colors that are slowly fading behind the treeline. The little crescent Moon's lit by the sun and forms the moon's crescent this is shown to be very bright, but its outline can be seen by Earthshine the light from the earth. This is a not so much astronomical picture but more show the beauty of science.

Northern and Southern Owls
In this picture we can see two balls of blue and red circles that appear to be the same shape. This is described as two glaring owl eyes glaring at Earth.
The circle to the left is M97 and is in the common constellation Ursa Major and even more commonly known as northern hemisphere as Owl Nebula, ans to the right we can see the visual counterpart of this same nebula, this is what we would really see if we looked into a telescope. They are about 2,000 times the width of Neptune's orbit. Nebula like this are only caused by the final phase in the life of the sun-like star.

The Antennae
This picture looks beautiful it looks like a cloud in the sky. But this is actually about 60 million light-yrs from Earth. And in this cloud there is really two large galaxies collided!!! These galaxies are NGC 4038 and NGC 4039. The act of the galaxies colliding goes from billions of years or even longer, no one knows because it no one has been around to observe that long. While this looks just like a cloud it is really about 500 thousand light-years long, a little longer than a cloud. This is an example of how things may look different than they really are in space.

two galaxy interacting
http://www.spacedaily.com/images/two-galaxy-interacting-bg.jpg
In this picture there are two galaxies that appear to be forming one, when in reality they are just passing by. There is one large galaxy and one relatively smaller one.

This picture has two galaxies that are farther apart than in the one on top but this one looks like the galaxy that is more spread out is "give" some of its self to the smaller one. This is the interaction of the two galaxy.

This picture looks to be one galaxy on its side and one facing us. The one on it's side looks to be cutting through the other one.

Frank Low
Frank Low
Frank Low lived an interesting life. It started when he was born on November 23, 1933 in a very expecting place to produce such an accomplished astronomer which was Mobile, Alabama. He moved to Texas as a child and when to college at Yale and then got his graduate degree in Philosophy at Rice, because he liked Texas so much. He had one wife, three children. And when he died he had six grandchildren that he enjoyed playing with. Frank Low started of working with solid state physics but then became interested in the new field of infrared astronomy. This new branch covered physics in astronomy and astrophysics that was useful in studies of astronomical objects visible in infrared radiation. In this field they discovered that the wavelength of this infrared light ranges from 0.75 to 300 microns, visible light is about 380 to 750 nanometers, this is useful in viewing astronomical objects because visible light is much easier scattered through the dust in space. Infrared also falls in between the visible radiation, that we can see, and which ranges from and submillimeter waves.
Frank Low created a telescope that could be put onto an spaceship that helps avoid atmospheric absorption of infrared radiation, this allows images to be much cleaner and thus allowing more information to be obtained from the picture. The spaceship that they used this first on was called the Douglas A-3 skywarrior. The telescope that was on it was a 2 inch one and was used in 1965 and 1966. Later when they learned how useful this new telescope that he had invented was NASA has a 12 inch one made to be boarded on a spaceship.
With this telescope Frank Low discovered that both Jupiter and Saturn emitted more energy than that energy that was caused by the solar radiation. This new discovery found prof that these planets are an internal source of energy that causes more energy than just the sun.
Some of the awards that he won include: the Rumford Prize, that he won in1986, Helen Warner Prize, that he won in 1968, Joseph Weber Award, that he won in 2003, Karl G. Jansky Lectureship, that he won in 2006, and the last award that he won was the Bruce Medal, that we won in 2006. He also had things named after him like, Kleinmann-Low Nebula and the Asteroid 12142 called Franklow this asteroid is in the main belt asteroid classification with an orbital period that consists of 2034.0120719 days.
His life ended at the age of 75 after a long illness on the sad day of June 11, 2009 in yet another state Tucson, Arizona. Frank Low was an astronomer that allowed new information to be shown about the galaxy that without him we would not have the knowledge about right now.

Bright Points on the Quiet Sun
This picture looks like a lot of little cells but it is really a very upclose view of solar surface it looks like a striking patch work of little granules because it is in a very high resolution picture of the what we would first think of as a quiet Sun with little activity. These granules are very hot the rising columns of plasma , the lighter parts of the cells, are edged by dark lanes of cooler and because they are cooler are also descending plasma. This high-resolution picture also helps us see that the dark lanes appear to be dotted alot of tinny contrasting bright points.This is very cool because we get to see, the sun, close up, and not how we normally think of our hot ball of gas a fire.

Ash and Lightning Above an Icelandic Volcano
This picture looks like ti should be about a story book with a very sad ending. IN reality this picture answers the question of the reason of how recent volcanic eruption in Iceland create so much ash. Even though the large ash plume was not uniques meaning there are storms like this one, the location was what made this pitcure very special, particularly wonderful it was in such well populated areas. The Eyjafjallajökull is a volcano in southern Iceland and this storm began to erupt, March 20. none of these eruption were unusually powerful, they were about the same power as most. This is a beautiful use of photography to help science.

Previous to this week it made the biggest eruptive prominences that has been ever viewed. In this picture we can view that the sun's prominence erupted in only a few hours and is was great fully captured in a video form by NASA's satellites. This picture helps us know what is going on in the sun and how it effects us.

Damage to Apollo 13
This picture is of Apollo 13. In this picture we see that an oxygen tank exploded and hurt their service module very badly. This had serious reprocutions because the astronomers were had to be forced to abandon the plan to make their third manned lunar landing. The refuse to this photo as a grainy grim photo, taken as the service module that had been drifting away, jettisoned only hours before the forced module's entry again and splashdown. The whole side panel of the side service module is shown that it was blown away and extensive internal damage is very noticeable. this is a very sad picture because we can not afford anymore mistakes.

Yukon Aurora with Star Trails
In this picture we see two interesting things. First we see stars that seem to be shown in a time laps and appear to be circling a center spot. The next thing that you can see is the green lights. This camera was fixed to a tripod to prevent shaking. The stars look like they are going around a circle because the earth rotates on its axis and because we are near the north we can see where the axes is. The green lights are caused by the high latitudes during March and April. These lights are called aurora lights. This picture is very interesting and amusing because it shows the beauty of nature and science and it is amazing how we can learn more about the earth's rotation by taking a picture.

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.

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.

Kemble's Cascade
In this picture there is an asterisms. An Asterism by deffinition is just a recognized patter of stars. An asterism is not one of the the 88 official constellations. the lagest asterism is the big dipper, not a costilation. This pretty chain of stars is near the costellation of Camelopardis. Another asterism is Kemble's Cascade, it is so large that is has about 20 stars nearly in a row creating this asterism. It is so large that is stretches over 5 times the width of a full moon. In this picture arounf the upper right to the lower left in the picture, Kemble's Cascade was created and made more popular by Lucan. In this picture we can see a lot of beautiful stars that are created by consillations and even more asterisms.

Mars Opposition 2010
http://apod.nasa.gov/apod/
In this picture Mars is at opposition. This means it is opposite the Sun in respect to Earth's sky. It is easy to spot even for a novice astronomer because it is closest to the fool moon. Mars is still over 99 million kilometers away but still not particularly close approach for the famous Red Planet. In this picture we can see a reddish planet very clearly. This is an example of the telescopic images possible in the coming days which means a lot more clear pictures of this red planet. In the picture you can even see the north polar cap of this red planet, that is how clear the picture is. It is the white part of the planet in the upper right hand corner. This planet is also about 14 arcseconds in angular diamiteter relitivly one hundreth of the size of the full moon.

M94: A New Perspective
This picture is a picture of the M94 Universe that only lies about 15 million light-years away. This universe is in the northern constellation of the hunting dogs. This picture looks like a swirling beautiful color. It looks like it goes on forever but in fact it is about 30,000 light-years across. Thanks to new multi-wavelength investigation the old knowledge and pictures of M94's inner spiral region only being surrounded by a faint broad ring of stars has been improved and revealed that this previous undetected spiral arms sweep across the outskirts of the galaxy's disk. This universe's optical wavelengths M94's outer spiral arms are followed in this remarkable discovery. This remarkable discovered enhances the outer disk structure. In this background galaxies are visible through the faint outer arms, while the three spiky foreground stars are in our own Milky Way. This picture is a beautiful picture of new technology.

The Spotty Surface of Betelgeuse
This picture was taken in Paris of the red supper giant or actually known as Betelgeuse. Betelgeuse is a really big star so big that in comparison to our star, if we put it in the middle of our solar system it would reach Jupiter. Because most stars only look like single dots even in large telescopes astronomers used interferometry to take this picture. This picture was taken at infrared wavelengths. In this picture there are two brights spots, big convective cells. These cells are rising from below the star's surface. They are bright because like lava coming out of a volcano they are hotter than the rest of the star. This is a really amazing picture when you take into acount that this star is about 600 light-years away.

Comet Haley's Nucleolus
This picture is a picture of a comet. In this picture you can see very well the actual nucleus of the comet. The nucleus is formed by the primordial stuff of the solar system. I believed that comets are basically very dirty icebergs but with new technology and ground-based telescopes we know the surrounding cloud of dust and gas around active comets close to a star are clearly resolving only the comet's coma. In 1986 European spacecraft, Giotto, became one of the first ever to get a photograph of a nucleus of a comet. This picture is of Halley's comet, one of the most popular comets. The nucleolus is potato shaped and about 15 kilometers wide. Haley's comet comes by only ever 76 years. So we do not get to see it very often, but know with the close up photo everyone can see it every day.

Astronomer Biography: Friedrich Georg Wilhelm von Struve
Friedrich Georg Struve was born in April 15, 1793 and lived a long and successful life and later died in November 23, 1864. He was born in Altona, Denmark. Altona Denmark is currently part of Germany. He was the son of a fellow astronomer, Jacob Struve. Counting himself and his father there would be five generations of astronomers in his family. These astronomers in his family include Otto Struve, Otto Wilhelm von Struve, and Hermann Struve. He married a woman named Emilie Wall in 1815. They had 12 children together but only 8 survived early childhood. One of his sons Genrickh Vasilevich Struve became a prominent chemist and his other son Bernhard Vasilyevish Struve served as a government official in Siberia. He had many children who grew up to become very influential people. Unfortunately his wife died in 1834, he later remarried Johanna Henriette Francisca Bartels. He had 6 more children with Joanna. One of which was Karl de Struve he served as a Russian Ambassador to The united States, Japan, and Netherlands. Jacob Struve, Friedrich Struve’s father moved his family to Livonia, in Imperial Russia. He did this in order to stay away from military services. Friedrich was first interested in the study of philology, the study of words. He studied at the University of Tartu which is in Estonia. Fortunately he found philology to be dull and then turned to astronomy for more excitement, which he studied at the same school. He started teaching in 1813 Tartu at the University of Tartu. He also observed at Dorpat Observatory on his free time which was also in Tartu. Later in his teaching career in 1820 he became a full time professor and still found time to managed to be the director of the Dorpat Observatory. In the Dorpat Observatory he researched double stars and geodesy. In 1839 he founded and directed a new Obervatory, the Pulkovo Observatory in St Petersburg. He was given many honors one of the most regarded ones was in 1826 he was honored by the Gold Medal of the Royal Astronomical Society. In 1862 Friedrich Georg Struve retired on account of his failing health. He died two years later on November 23,1864. Friedrich Struve did a lot of different work and observations but he is most widely known for his observations on double stars. He worked on his double star observations for many years. He exceeded past astronomers that observed double stars like William Herschel and John Herschel and Sir James South. He found many double stars in 1827 in this year he published his double star catalogue Catalogus novus stellarum duplicium. Struve’s observations were so exact and tedious that he made micrometric measurements of 2714 double stars around 1824, it took him many years to published his measurements in his work Stellarum duplicium et multiplicium mensurae micrometricae. He was also the first person to measure the parallax of the star Vega. Struve was one of the first Astronomers to recognize the effects of interstellar extinction even thought he could not provide a reason to help better understand the effects of interstellar extinction. He also was remarkably close to the modern estimate of the average rate of visual extinction he believed it was 1 mag per kpc and the modern believe is 0.7 to 1.0 mag per kpc. Along with Astronomy he started the Struve Geodetic Arc, which consisted of a chain of surveys triangulations stretching from Hammerfest, Norway to the Black Sea, ten countries wide and over 2,820km long.
