Comet erupts violently as Hubble watches
Lackluster comet LINEAR (C/1999 S4) unexpectedly threw astronomers a curve. Using the Hubble telescope, researchers were surprised to catch the icy comet in a brief, violent outburst when it blew off a piece of its crust, like a cork popping off a champagne bottle. The eruption, the comet's equivalent of a volcanic explosion (though temperatures are far below freezing, at about minus 100 degrees Fahrenheit in the icy regions of the nucleus or core), spewed a great deal of dust into space. This mist of dust reflected sunlight, dramatically increasing the comet's brightness over several hours.

Scientists building instruments for Mars Express are taking delivery this month of a software package to help them plan how and when to operate their instruments during each of the 2293 orbits the spacecraft will make during its first 687 E arth-days of operation. "The mission has to be planned orbit by orbit: there's no other way. STAT (Science Timeline Analysis Tool) is a very comprehensive software package for planning science operations," says Agustin Chicarro, Mars Express project scientist.

Leonids Bombard the Moon
Flashes produced by the impact of small cometary fragments on the surface of the Moon have been detected for the first time ever by scientists at the Astrophysics Institute of Andalusia (IAA-CSIC) and the Astrophysics Institute of the Canaries (IAC), in collaboration with investigators at the University of Monterrey and the Hispano-German Astronomical Centre of Calar Alto (CAHA) in Almeria (Spain). According to the scientists, these fragments - from the Leonid meteoroidal stream associated with Comet Tempel-Tuttle - have produced craters up to 30 metres in diameter. The conclusions of the observations, carried out in November 1999, are to appear in Nature and open up new avenues in the study of this violent phenomenon.
