A team of researchers has analyzed what little activity exists around the black hole at the center of our galaxy. By studying 3 million seconds of observations taken by the Chandra X-Ray Observatory, the team found that much of the nearby radiation comes from material that is ejected before reaching the black hole, with very little energy arising from the black hole itself.
Wally Pacholka. Earth rotates. Now we’re looking at the other side of the Milky Way—stars situated on the outer third of our galaxy. Orion “the hunter” hangs in freefall. Old-days Hawaiian stargazers saw this constellation not as a hunter but as a pair of hands playing a game of cat’s cradle (hei), snaring us in imaginative nets.
