Andrew Lange, astrophysicist, dies at 52

New York Times
27 January 2010

Andrew Lange, an astrophysicist whose balloon-borne measurements of light left over from the Big Bang played a key role in elucidating the shape and nature of the universe, was found dead on Jan. 22 in Los Angeles.

Dr. Lange devoted his career to a haze of faint microwaves that pervade the sky, providing a whispery ghost image of the universe when it was only 400,000 years old, before there were stars, galaxies or even atoms.

In the late 1990s, this work put him in the middle of one of the grandest quests in science, the effort to discern the fate of the universe - whether it would keep expanding forever or collapse one day into the fire from which it had emerged 14 billion years ago.

Dr. Lange presented at several SPIE conferences, and was scheduled to present at this year's SPIE Astronomical Telescopes and Instrumentation symposium.
