Photo by: Ligar Creative Commons In physics, focus is defined as that point in which the rays of light converge or meet; or diverge in the case when light is refracted or reflected. In optics, it can mean a number of things including: ? A lens? focal point ? A lens? or a telescope?s eyepiece?s
Pulsar is a contraction of two words, pulse and star (much like how quasar, meaning quasi-stellar object, was derived). By general definition, a pulsar is a small dense star (believed to be a neutron star) that emits mostly brief but intense bursts of electromagnetic radiation. The beam of radio wave produced is visible when pointed
The word intergalactic in astronomy may mean different things. It can be associated to travel, mediums, or space itself. From the word itself, the prefix ?inter-? means in between or across, and ?galactic? means galaxy.
