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.
Radio galaxies are a type of AGN galaxy that are very luminous at radio wavelengths between 10 MHz and 100 GHz. The radio emission is due to the synchrotron process which is inferred from its very smooth, broad-band nature and strong polarization. Synchrotron radiation is not confined to radio wavelengths.
