 This picture is a close up of a picture from the MAHLI also known as Mars Hand Lens Imager on the Curiosity Rover.This picture captures elongated crystal shapes formed by precipitation minerals dissolve in water. This is important with our exploration of mars because we must have some form of water to survive. This was likely the result of an ancient lake or riven on the surface of mars. They were found on the pink cliffs of the Pahrump hills on the base of Mount Sharp on mars. The inset of the Lincoln cent provided a scale. Mars dust itself, the penny is a MAHLI calibration target attached to the rover.

In this picture you are seeing an expanding nebula. No one is exactly sure what caused this expanding nebula. 170 years ago one of the southern star systems became the second brightest start. years later after ejecting more mass than the sun Etc car faded. This burst created the Homonuculus Nebula. The image we see was taken by Hubble space telescopein 1995, 2001 and 2008. the center is lit by a star. While the regions surrounding the star are expanding gas. the Eta Car still undergoes outbursts. IT mass and volatility make it a supernova candidate sometime in a few million years.

APOD 2.4

In this picture you are looking at what is called the crab nebula. It is a m1 object of the famous Charles messier from the 18^th century. Messier listed many thing that were not comments. The crab is supposed to be remnants of a supernova. A supernova is a explosion of a massive star. The crab pulsar is one of the most exotic objects for modern day astronomers. A crab pulsar is a neutron spinning 30 times a second and is viable as bright spot near the center. This nebula spans about 12 light years and is about 6500 light years away in the constellation Taurus .

2.3 APOD

In this picture you are seeing the Rosetta mission landing safely on the comet. On the left it appears Philaes feet are on the surface.  Philae bounced twice before settling and returning images from the surface. The surface panorama suggests the landers has come to rest titled and near a wall. The solar panels on it are getting less illumination than hoped. The instrument are working as planned and the data is being relays during communication time periods. They can only do this when the Spacecraft is above the landers new Horizon.

IN this picturing you are seeing a dusty and shape less emission of the region Sh2-155, also know as the Cave Nebula. Data was taken through narrowband filters tracks glow of ionized sulfur, hydrogen, and oxygen atoms in red, green, and blue. This nebula is about 2400 light years away. The picture lies on the plane of the milky way toward the northern constellation of Cepheus. Studies show that it has formed a massive Cepheus B Molecular cloud, young starts of Cepheus OB 3 association. The bright rim of ionized interstellar gas The bright rim energized by radiation from the hot stars, dominated by the bright star just above picture center. The ionization fronts are likely triggering collapsing cores and new star formation within. The cosmic cave is over 10 light-years across.

2.1 APOD

A spectre in the eastern Veil. In this picture it is showing the Eastern Veil Nebula. The Veil nebula is a large supernova remnant, the debris cloud from the death explosion of a massive start. The Veil is brought in a circular shape and covers about 3 degrees in the sky in Cygnus. Also known as the swan and is a constellation.  This portion of the eastern veil spans ½ degree the size of the moon. The estimated distance is 12 light years. The colors are formed by emission from hydrogen atoms in the remnant is show in red with strong emission from oxygen atoms in blue. The Western part lies in another season apparition called the witch’s broom which is ironic since today is Halloween.

In this photo you can see the greenish coma and told of comet siding spring. This comet is 2000 light years away and is is the messier 6 cluster. In the picture they seem very close together. They are in the same line of sight as the constellation named Scorpius. One of the constellation we have learned this year already.  The comet will be just passing mars by 139,500 km. Thats is almost 10 times closer that any know comet to by earth to this day. If it were to impact it would have no direct effect on us other than the comet dust moving 56km per second. The encounter will be followed closely by the spacecraft and martian orbit and rovers.

Observations (stargaze)

This Sunday Oct. 12 I went to the stargaze at pine view. It was my first stargaze and it was a awesome experience. For the first time i was able to pick out what we were learning in class in the sky. We saw the stars in the summer triangle. Also you could see the milky way dimly.  We pinpointed the summer constellations we have been learning and some of the new falls ones to come. We Looked at Saturn, mars, Specific stars and a galaxy outside of our own. I even saw Saturns ring through the telescope. The Andromeda galaxy is the only one we can see from earth that outside of our own. Overall the stargaze lasted from 730-930 and it was a great time. I am looking forward to the next stargaze!

Eclipse at moonset.This picture is capturing an eclipse. this picture was taken at the Pacific ocean and Chilean coast that lies below some clouds. What is seen in the predawn colors is a partially eclipsed moon growing dark. You can see the curved edge of planet earths shadow still cuts across the middle of the moon. From the southern hemisphere and much of eastern america the moon completely immersed within earths shadow.. To the west total phase could be followed for almost an hour. This makes the mood turn a dark red.  This captures the beauty of space.

Johannnes Hevelius

Johannes Hevelius was a German-Polish astronomer. He was born in Danzig Poland on January 28 1611. His Father’s name was Abraham Hewelke and his mother’s name was Kordula Hecker. His parents were part of a group of wealthy brewing merchants. As a Child Johannes was raised in wealthy family. Johannes as a child was sent to Gądecz to study his native language. He then started his studies at The University of Leiden. He studied jurisprudence. Jurisprudence is the theory or philosophy of law. As he travelled through England and France he decided to settle down in his native town in 1634 where he became a brewer and town councilor. He became famous for brewing jopen beer. In 1635 Johannes married a women named Katharine Rebeschke. In 1635 Johannes became part of a Beer-Brewing guild which he led from 1643 onwards. Around 1639 Johannes became interested in Astronomy.

 Johannes decided to build an observatory in his house. This observatory was filled with many instruments. Including a tubeless telescope of 150 ft. This telescope may have been the longest "tubed" telescope before the advent of the tubeless aerial telescope .His Observatory was so amazing it was visited by John II and Maria Gonzaga, king and queen of Poland. With this observatory Johannes observed sunspots and devoted four years to charting the lunar surface. What he discovered was that the moon's libration in longitude, and published his results in Selenographia (1647), a work which entitles him to be called the founder of lunar topography.

Some of his other works were, Prodromus cometicus (1665), Cometographia (1668), and Catalogus Stellarum Fixarum (dated 1687), catalog of 1564 stars. His first wife died in 1662 he then remarried the daughter of a merchant family. They had four children together. Elisabeth his second wife was considered the first female astronomer. She published two of his works even after his death.   He discovered four comets in the several years 1652, 1661, 1672 and 1677, and suggested the revolution of such bodies in parabolic tracks round the sun. On September 26, 1679 his observatory was destroyed by a fire. His instruments and books were destroyed. He did his best to repair the damage that had been done. He was able to repair enough to catch the great comet of 1680. Johannes decided to name the constellation Sextans after his lost instruments. Johannes health had depleted from the shock of the 1679 fire, and he died on his 76th birthday, January 28, 1687. Hevelius was buried in St. Catherine's Church in his hometown. Johannes had a good life. He has been named the “founder of lunar topography” and has described ten constellations. About 7 of those constellation are still used today by astronomers.  Johannes Hevelious observations and discovery of lunar topography has been a huge help to the study of astronomy and the world.

This APOD is named the bubble nebula.This picture was cataloged as NGC 7635 its also know simply as The Bubble Nebula.The diameter bubble offers evidence of violent processes at work. Below the bubble you see the a O star. An 0 star is several hundred thousand times more luminous and around 45 times more massive than the sun. The intense radiation of the sun blasts structures
of glowing gas against dense material surrounding the molecular cloud. This bubble lies 11,000 light years away towards the constellation called Cassiopea. Three color image is depicted of hydrogen, oxygen emissions were used for red and blue to great the green channel.This picture captures the immense space of space. . Also it amazes me how far away this bubble is. Overall this is one of the coolest pictures of have seen on the APOD site.

This picture is called A Launch and a Landing. This amazing picture was taken from Atlantic beach. Cape Canaveral. You can see that four identically framed digit images
are combined in the night skyscape. They person taking the picture did this to capture the flight of Falcon 9 rocket. It launch on September 21st. The Launches goal was to deliver Dragon X capsuled
filled with supplied for the ISS. You Can see the levels of the launch. First with its firing trails, then after separation as it is climbing to low earths orbit. Then at the horizon near the center of the re ignition is the controlled descent. When Falcons 9s first stage to a soft landing off the coast. This picture captures the technology we have invented and it is amazing. Also the different layers it to to combine to make this image must of been hard.

Observations of the Week.

Monday- I went outside around 8:45 and i saw the big dipper mars and Summer triangle. I did not notice the other constellation in the sky.
Tuesday- I observed the sky since i am new to observing the night sky i only saw the big and little dipper.
Wednesday. I Tried looking up again with no avail. Still struggling to identify the constellations i know that are up their.
Thursday. Had some progress. I noticed the summer triangle again. I somewhat made out the constellation Sagittarius. Learning and detecting constellations in the sky was harder than i thought.
Friday: I have not been able to look up at the sky today. Tonight i will gaze up at the heavens and continue to try and pinpoint the summer constellations that are floating up above.

APOD 1.4

In this picture you see a bunch of stars. Also know as a crowded star field covering over 2 Degrees within the flying constellation cygus. In this photo your eye is attracted to the redish orange cluster in the photo. What everyone sees is a cosmic cocoon. A cosmic cocoon is a compact star forming reagion. It has a long trail of obscuring interstellar dust clouds.This nebula is about 15 light years wide and about 4000 LY away. The star that is in the middles of this nebular is most likely  on a few thousand years old. This picture is truly mesmerizing. It captures the beauty and vastness of space.

Laniakea is our home super cluster of galaxies. In this picture it is showing exactly that. Not only is it one of the largest structures know it is also our home. The Laniakea cluster of galaxies contains thousands of galaxies, including our milky way. The Virgo cluster of galaxies are the closest cluster of galaxies to our own. In the picture the green areas have white dot galaxies and the white line indicate motion towards the center. The outline of Laniakea is in orange. The blue dot shows our location. The Laniakea is about 500 million light years and contains 100,000 times the mass of the Milky Way. Laniakea Means “immense heaven” in Hawaiian. This picture truly shows how small we are compared to the entire galaxy. I believe there must be some other life forms out there in other galaxies that we are not able to contact.

The Name of this picture is Moonbow beach. It shows a moonbow shining across the western horizon of a deserted beach scene in Molokai Island in Hawaii. The strange thing about this picture is there is no moon. A rainbow is produced by sunlight internally reflected in raindrops from the direction opposite of the sun back toward the observer. As the light passes from air to water and back to air again, longer wavelengths are refracted (bent) less than shorter ones resulting in the separation of colors. The Moonbow is produced as raindrops reflect moonlight from the direction opposite the Moon. That puts the Moon directly behind the photographer, still low and rising over the eastern horizon. This picture is truly breathtaking. I hope one day I will see a moonbow!

This picture is talking about the sky appeared to be full of color after a giant storm over Bangladesh. The unusual pattern that was created in the photo was due to atmospheric gravity waves. This created an aurora. Aurora’s are powered by collision with energetic particles seen at high altitudes. Airglow is due to chemiluminescence. Chemiluminescence is the emission of light as the result of a chemical reaction. Airglow (also called nightglow) is the very weak emission of light by a planetary atmosphere. Airglow keeps the night sky from ever being completely dark. With all these reactions happening its creates what the people of Tibet and china saw in the sky that night.
