Tycho Supernova

Tycho’s Supernova Remnant. In 1572, the Danish astronomer Tycho Brahe observed and studied the explosion of a star that became known as Tycho’s supernova.

It is located in the Constellation Cassiopeia, one of the 88 modern constellations. It was formed by the explosion observed at the beginning of November 1572 and discovered independently by several observers including the Danish observer Tycho Brahe who recorded the formation of the new star that bears his name.

This was one of the two or three most important events in the history of astronomy. The new star helped overthrow the old, classical models or conceptions of the universe. It ushered in an extraordinary revolution in astronomy, which began with the felt need to produce astrometric catalogs.
To obtain this image, scientists selected two narrow ranges of X-ray energies to isolate the material (silicon, colored red) moving away from Earth and heading toward us (silicon, colored blue).

The other colors in the image (yellow, green, blue-green, orange, and purple) represent a wide range of different energies and elements and a mixture of directions of movement. In this new composite image, X-ray data from the Chandra Observatory were combined with an optical image of stars in the same field of view, all digitized.

Medusa Galaxy

The irregular galaxy NGC 1427A will not survive long as an identifiable galaxy, passing through the Fornax cluster at nearly 600 kilometers per second (400 miles per second).

It is located approximately 130 million light-years away in the Ursa Major constellation.
