THUNDERBOLTS PICTURE OF THE DAY: AUGUST 5, 2013 From our contributor, Mel Acheson: NGC 4666 is one of the younger additions to the Virgo cluster of galaxies. It has also apparently given birth to another generation. The galaxy lies eight degrees south of M49, the great-grandmother of the Virgo cluster. Whether NGC 4666 is the daughter of M49 or of one of her many children has yet to be determined. The galaxy is directly in the line of ejection of many objects that M49 has thrown off: M87 at one end and 3C273 at the other. These objects are connected by electrical circuits that can be traced from their x-ray and radio emissions. In turn, lines of ejection from M87 and 3C273 extend the family tree of M49 to the third generation, and pairs of quasars on the opposite ends of these grandchildren’s spin axes mark the births of great-grandchildren. (Read Halton Arp’s discussion of ejection in his book Seeing Red, available from Mikamar Publishing.) SEE MORE---->>>>
