News & Views There seems to be something very healthy about astronomical research when, under the same cover, an event which took place in 1333 AD (Leonid bursts as a resonance meteoroid component from Comet Temple/Tuttle) is discussed followed by a paper on how we might more effectively search for extraterrestrial intelligence (in the optical). In this issue we also have a further paper on young clusters (Praesepe) and the low end of the stellar mass function (see IAJ , 1999, 26(1), 17). ...
