Nowadays, much of the universe's matter seems to be organized, as stars, solar systems, galaxies, and galaxy clusters are familiar sights of the local universe. However this was not always the case. By using the Spitzer Space Telescope to conduct a wide-area sky survey, SWIRE Legacy team hopes to explain how mature nearby galaxies evolved from the "element clumps" of the early universe.


Word of the Day
postliminy
  • In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
  • In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
The word 'postliminy' comes from a Latin word meaning 'threshold'.
