... Direct Observation of Extra-Solar Planets with an Infrared Interferometer . ... Current . Missions . ... Research . ... Direct observation of such extra-solar planets with an infrared interferometer is a difficult task because of the very high dynamic range required (typically 3?104 to 3?105), but not impossible if a very careful spatial filtering and calibration is imposed upon the recombined beams. ... We propose an observing strategy to monitor hot extra-solar planets of the 51 Peg class. ...

ARECIBO, P.R. -- The smog-shrouded atmosphere of Titan, Saturn's largest moon, has been parted by Earth-based radar to reveal the first evidence of liquid hydrocarbon lakes on its surface. The observations are reported by a Cornell University-led astronomy team working with the world's largest radio/radar telescope at the National Science Foundation's (NSF) Arecibo Observatory. ... The piggybacking Huygens probe is scheduled to plunge into the hazy Titan atmosphere and land on the moon's surface. ...
