How many intelligent civilizations could there be in our galaxy?

Monday, July 21st, 2008

The Drake Equation was devised by Dr. Frank Drake in 1960, in an attempt to estimate the number of extraterrestrial civilizations in our galaxy with which we might come in contact. The main purpose of the equation is to allow scientists to quantify the uncertainty of the factors which determine the number of such extraterrestrial civilizations.

Newly Discovered Galaxy Creates 4000 New Stars Per Year

Saturday, July 12th, 2008

Astronomers have uncovered an extreme stellar machine — a galaxy in the very remote universe pumping out stars at a surprising rate of up to 4,000 per year. In comparison, our own Milky Way galaxy turns out an average of just 10 stars per year.

The discovery, made possible by several telescopes including NASA’s Spitzer Space Telescope, goes against the most common theory of galaxy formation. According to the theory, called the Hierarchical Model, galaxies slowly bulk up their stars over time by absorbing tiny pieces of galaxies — and not in one big burst as observed in the newfound “Baby Boom” galaxy.
