Multispectral Galaxy Studies Contradict Theories 08/27/2004
The latest issue of Caltechs magazine Engineering and Science1 has beautiful pictures of galaxies taken in ultraviolet by the Galaxy Evolution Explorer (GALEX), and in the infrared by Hubbles sister, the Spitzer Space Telescope. Combining images of the same galaxy in visible, ultraviolet and infrared is helping astronomers figure out their structure, and as D. Christopher Martin claims, the origin and evolution of galaxies and stars. Why, then, at the end of the article, does he say this?
The interesting thing is that the history we have measured completely disagrees with some of the most recent models. (Emphasis added in all quotes.)He had just pointed out that our early results seem to be telling us that star formation was much more vigorous in the past and that something has changed very radically about star formation since that time....
Excellent article! It should have a thread of it's own.
