The weight is 56 lbs at senior level, and 35 lbs in underage level. It is mainly a men's event, though women's weight throw for distance is contested at university level.
A visible band image of Jupiter is shown below the radio image. Radio telescopes are much larger than optical telescopes because radio wavelengths are much longer than optical wavelengths. The longer wavelengths means that the radio waves have lower energy than optical light waves. In order to collect enough radio photons to detect a signal, the radio dishes must be very large.
Pulsars beam intense radio beams of radio waves out into space much like the beam from a lighthouse as it rotates. The Parkes radio telescope has been used to find over half of the 1,480 pulsars known.
