...Arecibo Observatory, astronomers from Cornell University determined that what the Defense Department's Clementine space probe showed as waves of frozen water is instead merely the rough surfaces of impact craters. If true, the news could mean a setback for space explorers hoping to use the ice to produce hydrogen and oxygen, the main components of rocket fuel. The team said its findings are more accurate than Clementine's, since the Arecibo Observatory has better resolution than the probe. But the existence of ice on the moon cannot be entirely ruled out, the team acknowledged, until scientists study the lunar...
This is the wrong attitude with which to leave Harvard. We spend countless hours pouring over unknowns which will remain unknowns--whether or not there is free will, when the sun will have used up all of its hydrogen, yada, yada, yada--while we spend offensively little time on the one sure thing in life: good food. An excellent soft-shell crab on a bed of arugula, after all, just...
...goes the theory, at least, and early studies of Hale-Bopp's gases bear this out. "We've found a type of hydrogen cyanide that's otherwise seen only in interstellar space," says Owen. "We saw it in Hyakutake too, but we thought it could be a fluke." Astronomers have found other gases they suspected would be there, including ammonia, methane, alcohol, formaldehyde and other organic compounds. Says Michael Mumma, an astronomer at NASA's Goddard Space Flight Center: "It's been suggested that both the building blocks of life and the water in our oceans fell to Earth...
...Purcell and H.I. Ewen detected radio waves from hydrogen atoms in interstellar space. This "21 centimeter line" is used by radioastronomers to map galaxies...
...universe will be even better than it is now," commander Kenneth Bowersox said just before liftoff. Since its 1993 repair, the Hubble Space Telescope has consistently delivered breathtaking views of the universe as it existed almost at the beginning of time, along with snapshots of billowing clouds of hydrogen gas and dust, 1 million-mph galaxy collisions, and stunning red and blue close-ups of Mars and Neptune. It has also provided valuable evidence for the ongoing debate on the precise age of our universe. Now, with a new near-infrared camera and two-dimensional spectrograph, said NASA's chief...
