What Is A Comet Made Of? - SpaceDaily  The researchers took one suspected chemical, carbon disulfide, and used spectra measured in the laboratory under conditions similar to those in a comet. The spectrum of this molecule is such that it could not have been detected by other methods. The technique makes it possible to look at the chemical composition of comets on their first visit to the inner solar system, which are difficult to reach with space probes and may have a different composition than comets that have been close to the sun many times, Jackson said. Detection of organic compounds such as benzene would show that these and more complex chemicals were present in the early solar system and could have contributed to the origins of life, he said.
Scientists Formulate Intelligent Glass That Blocks Heat Not Light - SpaceDaily  While conventional tints block both heat and light the coating, which is made from a derivative of vanadium dioxide, allows visible wavelengths of light through at all times but reflects infrared light when temperature rise over 29 degrees Celsius. Wavelengths of light in this region of the spectrum cause heating so blocking infrared reduces unwanted rays from the sun. The coating's ability to switch between absorbing and reflecting light means occupants benefit from the sun's heat in cooler conditions but when temperatures soar room heating is reduced by up to 50 per cent.

Saturn's Moon Titan: Planet Wannabe - SpaceDaily  Left:  The Solar System's largest exploitable oil well.  In January 2005, the European Space Agency's (ESA's) Huygens Probe will descend through Titan's atmosphere, sending back a detailed picture of the chemical interactions taking place there and, hopefully, giving scientists a glimpse into the chemistry that took place on early, prebiotic Earth. The Huygens Probe is part of the Cassini-Huygens mission to explore Saturn and its rings and moons. Titan is the only moon in our solar system with an atmosphere. Organic chemistry detected in that atmosphere has sparked the imagination of planetary scientists like the University of Arizona'z Jonathon Lunine.
