30, 13 months after NASA ended observations with the Extreme Ultraviolet Explorer spacecraft, the satellite plunged into Earth's atmosphere and burned up over central Egypt. Recording the emission and absorption of ultraviolet light with wavelengths from 90 to 120 nanometers, FUSE will fill the gap between the Hubble Space Telescope, which detects only the near ultraviolet, and the Extreme Ultraviolet Explorer. The ROSAT and Extreme Ultraviolet Explorer satellites have since revealed that Hyakutake is not alone--at least 10 comets, including Hale-Bopp, are now known to exhibit an X-ray glow as they near the sun. |
