Episode: Twenty Years of Hubble

Twenty Years of Hubble
On Saturday, April 24th, the Hubble Space Telescope will reach its 20th year in orbit. To mark the anniversary, we spoke to Ed Weiler, Chief Scientist for the Hubble mission from 1979 to 1998. He talked to us about the Hubble's early days--its conception, its first years in space, and its infamous optical problems, which blurred its view until a repair mission replaced faulty cameras in 1993. Podcast produced by David Levin. NOVA is produced by WGBH in Boston. Funding for NOVA is provided by ExxonMobil, David H. Koch, the Howard Hughes Medical Institute, the Corporation for Public Broadcasting, and public television viewers. To learn more about the Hubble, go to pbs.org/nova/hubble

For the last 40 years, the tapes from the Lunar Orbiter missions have collected dust in a warehouse, and the computer drives that could read them have gone the way of the dinosaurs...

NOVA | PBS > The Deciding Factor

But on a day-to-day basis, emotion plays a big role in the choices we make. In this podcast, we talked to Jennifer Lerner, a social psychologist at Harvard University, about how our feelings affect our financial decisions...

Vetenskapsradion På djupet > Genkniven från Umeå årets vetenskapliga genombrott

I Umeå upptäckte bakteriologiprofessorn Emmanuelle Charpentier mekanismerna i bakteriernas försvarssystem. Det ledde fram till en extremt effektiv och billig molekylär genteknisk kniv. På bara några år har forskningsfältet exploderat av aktivitet.
