1. Dozens killed in rare Afghanistan attack.
Twin suicide bombings killed dozens Tuesday in Afghanistan, most of them in a mass-scale sectarian attack on Shiite worshippers unlike anything the country has seen in its decade-long war. The terrorist attacks in the cities of Kabul and Mazar-e Sharif killed 58 people and wounded scores of others, officials said. A suicide bomber detonated a device at a Shiite shrine in Kabul as worshippers were marking the Shiite holy day of Ashura, Afghan Health Ministry spokesman Kargar Norughli said. Fifty-four people were killed and 150 were wounded, said Afghan Health Ministry spokesman Kargar Norughli.
2. Two black holes most massive ever found, astronomers say.

Black holes: They're the most destructive monsters in the universe. We already knew they can be powerfully massive. Now scientists say they've found the most massive ones yet, as reported in the journal Nature.

How big? The mass of each is about 10 billion times the mass of our sun. The previous black hole record holder, first measured in 1977, has a mass of about 6 billion suns. And for each black hole, the "event horizon" – basically areas from which nothing can escape their gravity – is about five times the distance between our sun and Pluto.
