A Cosmic Storm: When Galaxy Clusters Collide - Space.com  Astronomers have found what they are calling the perfect cosmic storm, a galaxy cluster pile-up so powerful its energy output is second only to the Big Bang. The cluster collision is the most powerful ever recorded and a fresh glimpse of the cluster merging process, where great swarms of galaxies smash into one another to form a single galactic structure. Finding observable evidence of such collisions bolsters theories that the universe formed in a hierarchical structure
New Structure Found Deep Within West Antarctic Ice Sheet - SpaceDaily   Scientists have found a remarkable new structure deep within the West Antarctic Ice Sheet which suggests that the whole ice sheet is more susceptible to future change than previously thought. The stability of the West Antarctic Ice Sheet has been hotly debated since the 1960s because of its potential to raise global sea level by around 5 m over several centuries. The potential impacts of a major change in the West Antarctic ice sheet are severe sea level rise will be fantastically expensive for developed nations with coastal cities and dire for poor populations in low-lying coastal areas.

Hubble Approaches The Final Frontier: The Dawn Of Galaxies - SpaceDaily  Left:  NASA's Hubble Space Telescope has at last glimpsed what could be the "end of the opening act" of galaxy formation. These faint sources illustrate how astronomers can begin to explore when the first galaxies formed and what their properties might be. Photo Credit: NASA  Detailed analyses of mankind's deepest optical view of the universe, the Hubble Ultra Deep Field (HUDF), by several expert teams, have at last identified what may turn out to be some of the earliest star-forming galaxies. Astronomers are now debating whether the hottest stars in these early galaxies may have provided enough radiation to "lift a curtain" of cold, primordial hydrogen that cooled after the big bang.
