Index of 1999 NASA News Releases: http://www.nasa.gov/releases/1999/index.html ***************************** Video File for Nov. 22, 1999 ITEM 1 - WHEN GALAXIES COLLIDE - STSCI Hubble astronomers conducting research on a class of galaxies called ultra-luminous infrared galaxies (ULIRG) have discovered that over two dozen of these are found within "nests" of galaxies, apparently engaged in multiple collisions that lead to fiery pile- ups of three, four or even five galaxies smashing together. Contact at Space Telescope Science Institute, Baltimore, MD: Ray Villard (Phone 410/338-4707). Contact at NASA Headquarters, Washington, DC: Donald Savage (Phone 202/358-1547). ITEM 1a - ANIMATION OF HUBBLE-SPACE TELESCOPE--------------TRT :13 Multiple galaxy collisions surprise Hubble astronomers. This animation shows the Hubble Space Telescope pointing toward the galaxies while in orbit. ITEM 1b- COLLIDING GALAXIES--------------------------------TRT :13 This simulation shows multiple galaxies colliding. ITEM 1c - FIVE IMAGES OF ULIRG GALAXIES-------------------TRT 1:14 These Hubble Space Telescope pictures, part of a 3-year study, reveal a surprising amount of structure in these ULIRG, or Ultraluminous Infrared Galaxies. The bright, infrared glow is caused by a firestorm of star birth triggered by multiple galaxy pile-ups. ITEM 1d - INTERVIEW EXCERPTS-------------------------------TRT :39 Dr. Kirk Borne, Principal Investigator, ULIRG (Ultraluminous Infrared Galaxies) ITEM 2 - VOLCANO ON JOVIAN MOON, IO (replay) - JPL Jupiter's fiery moon Io is providing scientists with a window on volcanic activity and colossal lava flows similar to those that raged on Earth eons ago, thanks to new pictures and data gathered by NASA's Galileo spacecraft. The sharp images of Io were taken on Oct. 11 during the closest-ever spacecraft flyby of the moon, when Galileo dipped to just 380 miles (611 kilometers) above Io's surface. The new data reveal that Io, the most volcanic body in the solar system, is even more active than previously suspected, with more than 100 erupting volcanoes. Contact at NASA Jet Propulsion Laboratory, Pasadena, CA: Jane Platt (Phone 818/354-5011). Contact at NASA Headquarters, Washington, DC: Doug Isbell (Phone 202/358-1753). ITEM 2a - VOLCANIC IO--------------------------------------TRT :53 Images of the Prometheus volcano on Jupiteršs moon Io reveal two hot spots and a volcanic caldera, or crater, seven times larger than Hawaiišs Kilauea caldera. By studying Io, scientists hope to learn more about the geological processes that shaped Earth, Mars and other planets. ITEM 2b - B-ROLL: FOOTAGE OF HAWAIIAN KILAUEA CALDERA-----TRT 1:29 ITEM 2c - ANIMATION OF GALILEO-----------------------------TRT :53 NASAšs Galileo spacecraft flew by Jupiteršs moon Io on October 10, 1999, at a distance of about 15,000 km or 9,400 miles. Images of Io were taken by the Near-Infrared Mapping Spectrometer (NIMS) onboard the spacecraft. ITEM 3 - MARS MISSIONS CLIP REEL (file footage)--approx. TRT 35:00 Mars missions resource reel (file footage) features various missions, images from Hubble Space Telescope, 3-D mapping, etc. ---------- Unless otherwise noted, ALL TIMES ARE EASTERN.
