, 2010 Drain away the earth's oceans and a global pattern of great ridges appears. Adjacent to these continental and undersea mountain ranges are layers of silt and clay, so thick that they fill the gaps between ridges, creating extensive plateaus. Ranging across this planet's higher latitudes are thousands of tiny replicas of these ridge systems. These esker

Chandra Observations of A2670 and A2107: A Comet Galaxy and cDs with Large Peculiar Velocities
, 2005 We present an analysis of Chandra observations of the galaxy clusters A2670 and A2107. Their cD galaxies have large peculiar velocities (>200km/s) and thus the clusters appear to be undergoing mergers.
