APOD 2.5

http://apod.nasa.gov/apod/ap120103.html
There were mixtures of red and green light. There were many rays, distinct curtains, and even an auroral corona. If you look in the background you can see some stars and a beautiful landscape underneath this vast snowy terrain. With the sun getting more active every year, the auroras will be even brighter and spectactular.

This place is ideal for the Atacama Large Millimeter Array(ALMA), which is designed to explore the universe at wavelengths over 1,000 times longer than visible light. The ALMA is an international partnership between Europe, North America and East Asia and is the largest astronomical project in existence.

Comet Lovejoy appears to be fading. The beautiful tail of this comet spreads across the entire south celestial pole. This is a stereographic projection used to map the image pixels below the camera and is known as the little planet projection. In  Australia where this picture was taken, the night sky was covered with stars. With the help of other celestial highlights, this comet in the milky way can be identified. To the right of the planet are the celestial stars, Canopus and

January 4th 2012
Time: 10-2:00
My backyard
Cloudy skies

In order to observe a good portion of this eventful night, I set up a blanket on my patio in my backyard and looked at the stars from 11pm until 2 in the morning. I was able to observe the planet Mars which was bright and orange in color. And I was also able to observe various different bright stars like Sirius.

Planets: Mars (orange in color and bright). I also detected and identified 3 different constellations; Gemeni, Lepus, Orion. This was the night the Quadrantids meteor shower was said to happen so I also attempted to see it. Most meteors were to small to be visible, yet I spotted various bright meteors with their tails stretching far acorss the sky.


Johann Heinrich von Mädler Biography

Johann Heinrich von Mädler Biography

Johann Madler was born in Berlin in 1794. Madler’s became interested in astronomy when he saw a comet as a child. Because he was Orphaned early in his life, Madler was responsible for raising his younger sisters. Madler studied astronomy and mathematics at the University of Berlin. During his time there he studied under both Encke and Ohm. 

Madler became a tutor in order to give some of his earnings to his family. While working as a tutor, Madler came into contact with a wealthy banker and amateur astronomer named Wilhelm Beer. Beer realized Madler’s abilities and offered him a position at the observatory that Beer was building. Madler, with Beer’s help, made a number of important contributions to astronomy.

While he worked at Beer’s observatory, Madler made the most comprehensive map of the moon to date. He was the first to divide the moon into four separate quadrants. His maps of the moon were considered its most accurate documentation for the three decades after they were created.

Madler also made observations of Mars. He and Beer were the first astronomers to map the planet. Using Hershel’s calculations, they attempted to determine Mars’ rotational period, eventually coming within 1.1 seconds of finding the exact period. Though Madler was most famous for his observations of Mars and the moon, he made observations of Jupiter early in his career as well. His first contribution to astronomy was his discovery of two dark spots on Jupiter’s rings.

He also developed the Central Sun Hypothesis which said that the center of the universe, or more accurately the center of the universe’s gravity, is located in the star cluster known as the Pleiades. To find this, Madler observed the motions of over 3,000 stars. Though this hypothesis was eventually proven false, his observations were used by later astronomers.

After working with Beer, Madler accepted a position and became director of the Dorpat Observatory in Estonia. Madler also made great meteorological observations. He made the most accurate calculations of Earth’s tropical year. Madler published his complete works, History of Descriptive Astronomy, in 1873. Madler died in 1874 in Germany.

APOD 2.7

January 8th, 2012: http://apod.nasa.gov/apod/ap120108.html

The picture for the January 8th, 2012 APOD entry is that of a of a meteor seen over a lighthouse. A forgotten constellation named the Quadrantid Meteor reappears every year during the colder parts of the year. In the early hours on January 4 2012, the constellation was visible. It is situated near the boundaries of the modern constellations Hercules, Bootes, and Draco. Many of the Quadrantid meteors this year were dim, yet some were still bright and easily visible to the naked eye.
