Searching for Black Holes
- 1991 ----- color ----- 57 min ----- vhs
- (Astronomers series, Part 2) At the center of galaxy NGC 1275--some 200 million light years from earth--there might be a super-massive black hole, one of the most intriguing objects in the universe. In an attempt to map the galaxy and look deep into its heart, John Conway links an international team of astronomers and radio telescopes throughout Europe and America. This linkage--in effect a telescope 6,000 miles in diameter--produces an excellent picture of NGC 1275. Also meet Jessie Greenstein, the co-discoverer of quasars, the most powerful known objects in the universe, and Italian radio astronomer Tiziana Venturi, who describes what she finds so enthralling about astronomy.
