... New results in radio observations of comets and asteroids . In the last decade, technological improvements in radio observatories have made possible some interesting studies both of cometary comae and of asteroid surfaces. ... Long-period comets with more than an order of magnitude lower gas production than that of comet 1P/Halley have been detected and mapped, providing constraints on total gas production, gas outflow velocities, coma asymmetries and excitation conditions. ...

... Many observatories around the world will follow these events, with the purpose of obtaining accurate measurements of the angular diameter of this red giant, from the recording of the lightcurve during the disappearance (or reappearance) behind the limb of the Moon. ... 6 November 1998: both disappearance and reappearance recorded under very good conditions at the TIRGO observatory by A. Richichi . ... A preliminary analysis confirms the findings of the previous event observed in February (see below)...

Methods such as "self-coherence" allow for the retrieval of signals buried far b elow the noise level. In particular, at SNRs Ў 1 the noise may suppress high-order coefficients in the eclipse signal's Fourier series. ...

... The Gamma-ray Bursts -- Topical as Ever . Earth is hit daily by some three bursts of gamma-rays, isotropically from all directions, with energy fluxes S = 10 -5 +/- 3 erg/cm 2 s, energies integral S dt = 10 -5 +/- 2.5 erg/cm 2 , durations dt between 10 -3 s and 10 3 = 10 -3.7 s, power-law spectra like superpositions of cooling sparks with peak fluxes straddling 1 MeV, and with composite lightcurves which differ vastly from burst to burst whereby hardness drops during subbursts. ...

... Although many of the images are used for teacher-driven activities, students do have the opportunity to work with scientists on original research projects. ... The primary goal is to have teachers experience astronomy research and then to bring the research data into their classrooms via the internet. ... They also learn how to process their data, build a solar telescope to take home to their classrooms, and learn background information from astronomers in each of the three research areas. ...
