Las Campanas Observatory is an astronomical observatory in the southern Atacama desert in Chile. It is owned and operated by the Carnegie Institution for Science. It was built in 1969 as the main observing site for the Carnegie Institution for Science. The headquarters is located in La Serena, Chile and the observatory is about northeast of the city. The observatory is at above sea level.
On February 24, 1987, Ian Shelton and Oscar Duhalde first saw the Supernova 1987A (SN 1987A).
There are also the small "Pi of the sky" wide-angle cameras that filmed the gamma ray burst GRB 080319B in 2008. This was the largest explosion ever seen in the Universe, and could have been seen without a telescope.
Tyler Perry
Tyler Perry (born September 13, 1969 in New Orleans) is an African American playwright and actor, whose work plays are usually for encouragement to African Americans. Having started writing plays at age 18, Perry created a successful touring theater company, videos of whose performances were sold on DVD. As of March 2005, the plays had grossed over $75 million in ticket and DVD sales. He is well known for his plays on Madea. At age 16, he had his first name legally changed from Emmitt to Tyler in an effort to distance himself from his father.

Spectrograph
A spectrograph is an instrument that breaks up a wave into a frequency spectrum. These could be sound, light or radio waves. For example the frequency spectrum of light is the brightness (intensity) and the amount of each colour. There are several kinds of machines called "spectrographs", used to look at different waves. The term was first used in 1884.
A spectrograph is closely related to a polychromator.
In astronomy, the first spectrographs used photographic paper as the detector. The star spectral classification and discovery of the main sequence, Hubble's law and the Hubble sequence were all made using photographic paper. The plant pigment phytochrome was discovered using a spectrograph that used living plants as the detector. New spectrographs use electronic detectors, such as CCDs which can be used for both visible and UV light. The type of detector depends on the wavelengths of light to be recorded.
An echelle spectrograph is a special machine which is able to break up light waves, with a high resolution and little interference. It does this by using very narrow slits which breaks light into beams, and then breaking up those beams again.
Ken Mogi
Mogi was born 20 October 1962 in Nakano Ward, Tokyo. His family soon moved to Kasukabe, Saitama where he grew up. He has an unusual hairstyle and cuts his own hair.
He graduated from the University of Tokyo in 1985 with a degree in science and in 1987 with a degree in law. Mogi earned his Ph.D. in 1992. His thesis was called "Mathematical Model of Muscle Contraction".
In 2009, Japan's National Tax Agency said that Mogi had broken tax laws. Mogi did not pay all of his taxes for three years. He tried to hide income of ¥400,000,000. NHK fired Mogi from a TV program because of his bad behavior.
Occupy Wall Street
Occupy Wall Street was a protest that started in 2011 in New York City and spread into other cities all over the United States. Citizens protested against how poor and wealthy people have lived in different ways and are treated differently by other people, and also against the way corporations used their money. People in New York started protesting in Zuccotti Park on September 17, and some people decided to camp there overnight. It grew to include several thousand people, with many different political views. Protesters included some communists, political moderates, liberals, conservatives, and libertarians.
Many of the Occupy protests in the rest of the country only started as in the middle of October. In some places, like Denver, Oakland, and New York City itself, police acted violently. In some places, including Miami, the protests were peaceful and some police officers supported the protests. After 2011 the numbers of people involved dwindled away.
Thelma
Thelma is a female given name which in Greek means "will and volition". There are many celebrities going under this feminine name. Also, there are many television series featuring characters with the name "Thelma". In addition, a deadly tropical cyclone by the name "Thelma" struck the Philippines in latter 1991.
First light (astronomy)
In astronomy, first light is the first time a telescope is used to look at the Universe. This is often not the first time the telescope has been used. Tests will have been done during daylight to make sure everything is working. Images taken during first light are not normally of scientific interest. They are usually poor quality as the parts of the telescope have not been properly adjusted for best performance. Usually, a well-known and spectacular astronomical object is chosen. First light is always a moment of great excitement, both for the people who designed and built the telescope, and for the astronomical community.
For example, the 200-inch Hale Telescope saw first light January 26, 1949, targeting a nebula located in the constellation Monoceros. under the direction of American astronomer Edwin Hubble. The image was published in many magazines.
The Large Binocular Telescope had its first light with a single primary mirror on October 12, 2005. This was a view of NGC 891, a spiral galaxy in the Andromeda constellation . The second mirror was installed in January 2006 and the telescope became fully operational in January 2008.
In physical cosmology, first light refers to the light coming from the first generation of hyperstars. These were formed less than a billion years after the big bang, bringing an end to the cosmological Dark Ages.
Esther Vergeer
Esther Mary Vergeer (born 18 July 1981, Woerden) is a Dutch wheelchair tennis player. Vergeer has not lost a match in singles since February 2003. She has won 39 Grand Slam titles, five Paralympic Gold Medals and 21 Masters titles. Vergeer has been the world number one since 1999. Vergeer is also a former wheelchair basketball player. She was part of the team which won the European Championships in 1997.
In March 1988 after a swimming lesson Vergeer became dizzy and passed out. Vergeer was just six years old at the time. Doctors found out that Vergeer was bleeding in her head. The bleeding had caused Vergeer to pass out. Vergeer had the blood removed. Six weeks later she went home. Yet the next year in June Vergeer had more headaches. She also had pressure behind the eyes and pain in her neck. The doctors could not find what was wrong. They sent her home. In October, doctors found Vergeer to be bleeding in her head again. They drained the blood. The doctors also found that Vergeer had an Vascular myelopathy. This abnormality caused the strokes that Vergeer experienced. On the 15 of January 1990, after a nine-hour operation Vergeer was unable to move her legs. The operation took place near to her spinal cord. Vergeer had one final operation in March but still could not move her legs.
