X-ray source at the galactic center

October 26

2000 - Using the Chandra Space Telescope MIT's Fred Baganoff and colleagues recorded a powerful X-ray outburst toward "Sagittarius A*," an intense radio source that astronomers believe is powered by the black hole.  X-ray emissions from Sagittarius A* became 45 times brighter than normal during just a few minutes observations then declined to pre-flare levels a few hours later.
"This is extremely exciting because it's the first time we have seen our own neighborhood supermassive black hole devour a chunk of material," said Baganoff. "It's as if the material there sent us a postcard just before it fell in."

1331 - Ismail Abu'l Fida died in Syria. An Ayyubid dynasty historian and geographer, born in November 1273 in Damascus, he wrote a geographic work with the title: 'The true position of the countries' (Thakwim el-Boldan). In this book he used astronomical determined locations. A Moon crater is named to honor him (Abulfeda).

It is my conclusion that human evolution and the motions of matter in space are intrinsically linked. The observation and understanding of the complexity of biological history on Earth cannot be complete without the tandem observation and understanding of a dynamic greater cosmos. - SpaceGene
