... 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. ...

... The Hubble Space Telescope is a collaboration between ESA and NASA. ... In many ways Hubble has revolutionised modern astronomy, by not only being an efficient tool for making new discoveries, but also by driving astronomical research in general. ... However, in the last few microseconds before light arrives at telescope mirrors on Earth it must travel through our turbulent atmosphere and the fine cosmic details become blurred. ... Putting a telescope in space is one way of evading this problem. ...

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. ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...

... Infrared observations of RCBs show that, even at maximum light, there are copious amounts of dust surrounding the star. ... Therefore the obscuring dust can only cover a fraction of the stellar surface. The picture that emerges (Fig. 2 ) is that at a particular phase in the pulsation cycle, conditions in the photosphere can compel the carbon-rich gas to be expelled from a part of the stellar surface to cool, condense and form dust grains. ...
