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 18th 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.

2.2 Apod

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.
