Researchers in the past have studied the black hole at the center of our own galaxy, the Milky Way, explains Shep Doeleman, assistant director of MIT's Haystack observatory and lead author of the study. But that one is apparently a bit of a weakling as far as black holes go, with a mass just 4 million times that of the sun, and it doesn't appear to produce these polar jets. The black hole at the center of M87 is 6.5 billion times the mass of the sun, and its plasma beams are marvelous.
Andy Murray is the first British man to reach a Wimbledon singles final for 74 years after beating Jo-Wilfried Tsonga in a nail biting match.
Andy powered through the first two sets 6-3, 6-4 but Tsonga fought back to take the third 6-3.
Murray seemed to lose focus in the fourth set but pulled it back to win 7-5.
He will now face Roger Federer in the final on Sunday.
