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.
MICROWAVE TELESCOPE, THE PARTS: * A microwave/millimeter-wave telescope can observe space objects in a frequency range between 70 and 300 GHz * some X-ray telescopes use Wolter telescopes composed of ring-shaped 'glancing' mirrors made of heavy metals that are able to reflect the rays just a few degrees.
