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.
Reflector. A type of telescope used in most astronomy research is a reflecting telescope. Reflector telescopes use one mirror, or a combination of mirrors, to reflect light and form an image to the viewer. The design of this telescope allows astronomers to see things way out in space that don't emit much light.
