Instead of inspiration, along comes Clippy, the annoying little pop-up man with his bobbing eyebrows and balloon full of intrusive questions. Would you like help? Astronomers have discovered that the nearby star Epsilon Eridani has two rocky asteroid belts and an outer icy ring, making it a triple-ring system. The inner asteroid belt is a virtual twin of the belt in our solar system, while the outer asteroid belt holds 20 times more material.
Moreover, the presence of these three rings of material implies that unseen planets confine and shape them. Drawing on records dating back to the journals of Henry David Thoreau, scientists at Harvard University have found that different plant families near Walden Pond in Concord, Mass. The inner asteroid belt is a…. Astronomers think that many — perhaps all — galaxies in the universe contain massive black holes at their centers. New observations with the Submillimeter Array now suggest that such colossal black holes were common even 12 billion years ago, when the universe was only 1.
The new conclusion comes from the discovery of two distant galaxies, both with black holes at their heart, which are involved in a spectacular collision.
