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.

1.8 APOD

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!

1.7 APOD

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.

1.6 APOD

http://apod.nasa.gov/apod/ap141002.html

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.
