Four billion years from now, the Milky Way galaxy as we know it will cease to exist.
Our Milky Way is bound for a head-on collision with the similar-sized Andromeda galaxy, researchers announced today (May 31). Over time, the huge galactic smashup will create an entirely new hybrid galaxy, one likely bearing an elliptical shape rather than the Milky Way's trademark spiral-armed disk.
"We do know of other galaxies in the local universe around us that are in the process of colliding and merging," Roeland van der Marel, of the Space Telescope Science Institute in Baltimore, told reporters today. "However, what makes the future merger of the Andromeda galaxy and the Milky Way so special is that it will happen to us."
Astronomers have long known that the Milky Way and Andromeda, which is also known as M31, are barrelling toward one another at a speed of about 250,000 mph (400,000 kph). They have also long suspected that the two galaxies may slam into each other billions of years down the road. [Milky Way Slams Into Andromeda (Artist Images)]

CNN Ratings Hit 20-Year Low


CNN’s ratings are down … again. CNN’s May ratings plummeted again, bringing the network to its lowest monthly primetime total viewers since 1991. In response, CNN is rejiggering its lineup, announcing that ABC News’ John Berman would be a new contributor on it’s early morning show, and that Anthony Bourdain, best known for his cooking ability, will be joining CNN in 2013.



Piers Morgan has been a complete ratings disaster – his 9 p.m. slot clocked in at the lowest CNN ratings for that time in two decades. CNN is averaging just 288,000 total day viewers, and only 389,000 viewers in primetime – down over 61% from May 2011 during the day, and down over 51% from May 2011 during primetime.
