Putting Life Into Perspective (Link Round-Up 12/5/11)


"I think there are two things that are really exciting about Kepler-22b," said Natalie Batalha, the deputy science team lead at Ames. "One is that it's right in the middle of this habitable zone.  
"The second thing that's really exciting is it's orbiting a star very, very similar to our own sun. This is a solar analogue, almost a solar twin, very similar to our own sun and you've got a planet 2.4 times the size of the Earth right smack in the habitable zone."
One of these newly surveyed monsters, which weighs as much as 21 billion Suns, is in an egg-shaped swirl of stars known as NGC 4889, the brightest galaxy in a sprawling cloud of thousands of galaxies about 336 million light-years away in the Coma constellation. 
The other black hole, a graveyard for the equivalent of 9.7 billion Suns, more or less, lurks in the center of NGC 3842, a galaxy that anchors another cluster known as Abell 1367, about 331 million light-years away in Leo.
Man fatally shot in Chicago's Uptown neighborhood
The shooting is related to gang activity in the area, according to Ald. James Cappleman (46th), who issued an alert to constituents after the shooting. 
Cappleman said that compared to last year, there is a decrease in shootings in Uptown, “but one shooting is still too many.”
