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.

APOD 4.7

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.

APOD 4.4
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.
