Neutron star had large magnetic fields, then electromagnetic waves would be emitted. Unbeknown to him, radio astronomer Antony Hewish and his research assistant Jocelyn Bell at Cambridge were shortly to detect radio pulses from stars that are now believed to be highly magnetized, rapidly spinning neutron stars, known as pulsars. In 1965, Antony Hewish and Samuel Okoye discovered "an unusual source of high radio brightness temperature in the Crab Nebula". This source turned out to be the Crab Pulsar that resulted from the great supernova of 1054. In 1967, Iosif Shklovsky examined the X-ray and optical observations of Scorpius X-1 and correctly
Beam projector is used to the extent that it once was, as newer fixtures and PAR lamps have created easier ways to produce the effect. A similar effect can be produced using ETC Source Four PAR fixtures with a clear lens. A snoot/top hat can be added to control spill. Beam projector A beam projector is a lenseless stage lighting instrument with very little beam spread. It uses two reflectors. The primary reflector is a parabolic reflector and the secondary reflector is a spherical reflector. The parabolic reflector organizes the light into nearly parallel beams, and the spherical reflector is placed in
