This NASA composite image received today shows the galaxy cluster 1E 0657-56, also known as the "bullet cluster". A huge collision between two clusters of galaxies has provided the first evidence of the existence of the universe´s mysterious dark matter, researchers said today. "This is the most energetic cosmic event, besides the Big Bang, which we know about", said Maxim Markevitch of the Harvard-Smithsonian Center for Astrophysics.

A replica of the Cenozoic Era skeleton of a Carodnia vieirai, similar to a large anteater is presented during a news conference by researchers from the Federal University of Rio de Janeiro. Researchers presented the replica as the most complete skeleton ever found of a Cenozoic mammal in South America, modeled from what they estimate to be 50% of the animal´s real fossilized bones discovered on the outskirts of Rio de Janeiro a few years ago.
