The Antennae Galaxies in Collision
Located in the Constellation Corvus, The Crow, are two galaxies colliding. When two galaxies collide, their central stars seldom take part in the destruction. The reason behind this is that galaxies are comprised of a vast amount of space, mostly containing gas and dust. The churning up of the gases between the two galaxies will inevitably spark the birth of millions of stars.

Biography: Karl Schwarzchild
Life
Karl Schwarzchild grew up in a well off home in Frankfurt, Germany. Brought up in a Jewish home in early 20th century, Schwarzchild attended primary school until the age of eleven and had a father who was very active in the community. After primary school, Schwarzchild studied at two universities. One at Strasbourg and another at Munich. He developed a keen aptitude in physics and astronomy. At the age of twenty three he obtained a doctorate and began working at the Kuffner Observatory as an assistant in 1897.
Starting in 1901, Schwarzchild was a professor at the institute of Gottingen. He quickly rose from this position and became the director of the Gottingen Observatory in 1909. This led to a job as the director of the Astrophysical Observatory in Potsdam.
During the heat of World War I in 1914, Schwarzchild developed a skin disease that made him extremely ill. Regardless of the struggle this presented for him, Schwarzchild was still able to produce three papers. Two of the papers were on the theory of relativity and the third was regarding quantum theory. These papers showed explicit solutions to the Einstein field equations. It was the work on these three papers which yeilded what is not commonly known as the "Schwarzchild metric".
Work and Legacy
Black Holes: Schwarzchild predicted that the spacetime of a black hole is curved in a way that caused the future light cones to tip inward. This was shown vividly through the image below.
Event Horizon: From the discovery of light curves came the discovery of event horizons in black holes. What the event horizon does is show a distinguished line between where light can and cannot escape from a black hole as a cause of the light curve and gravitational pull of the mass itself.
Einstein's Theory of Relativity: Applied successfully to Schwarzchild's predictions.

Star Gaze at Pine View School, Service Road
March 1st marked the date of yet another Star Gaze on the Pine View Campus. Mr. Chap Percival and Steven Dacey led the Gaze by setting up telescopes for the student to use in order to view an array of space objects up close. During the star gaze we pointed out constellations that we went over in class during the preceding few weeks. We also were shown Canopus, one of the brighter stars in the night sky that is shown in a constellation which we have yet to go over in class, Carina, The Keel. Mr. Percival used his laser pointer to help guide the other students and myself through the constellations by using a process called "star hopping". Other astronomical objects viewed included two emission nebulae and Jupiter through the smaller telescope. In the telescope with Jupiter, four moons were visible at the start of the night. Later on, Mr. Percival changed this view to show a binary star system.
