What is a telescope Lens? A telescope Lens comes in different sizes. One may find one in the form of a small plastic toy; another may find a telescope Lens that is worth millions of dollars. There are telescopes found in science laboratories all over the globe, there are telescopes in observatories, there are even […]
Two different numbers, namely the Latitude and the Longitude, usually characterize various locations on Earth. This helps people in determining specific locations on the map, and the respective distances between two points on the Earth.
Lagrange points are areas in outer space characterized by gravity along the circular motions in outer space. This phenomenon was theorized by a mathematician from France, Louis Lagrange while studying gravity, most specifically the Three body problem. He aimed to investigate why a third small body would rotate a certain body (Earth), which is also
Vignetting is the effect in photography or in optics wherein the brightness on the periphery of the photo or the field of view is reduced to emphasize the center of the field. This usually creates an attractive effect on photos. However, vignetting occurs in telescopes which causes an unpleasant effect because the field of view
A perfect time to stargaze is during a moonless sky and at a location where there is a minimum of light pollution and sky glow. When we observe stars, we observe them according to their apparent magnitude or the brightness that we see by simply observing using the naked eye. In astronomy, this particular radiant
Photo by: Beland Creative Commons Voids are those huge dimensions or sizes of space that have galaxies and groups of galaxies within its area or scope. A galaxy has plenty of stars, planetary bits and pieces, gas, dust and dark matter. Galaxies have millions or even billions of stars. The Sun is a part of
In astronomy, focal length is primarily used when referring to telescopes. It is the distance light travels starting from the lens of a telescope down to the point where it is focused. While in optics, focal length is simply defined as the strength by which an optical system (like a telescope) converges (focuses) or diverges
A TNO or Trans Neptunian object is any minor planet orbiting the sun in our solar system beyond Neptune, or at a distance which is more than Neptune’s (on average). Known divisions of bodies beyond Neptune which are still part of the solar system are the Kuiper belt, the scattered disk and the Oort cloud.

An eyepiece, or ocular lens, is basically the lens through which one views in optical devices such as telescopes and microscopes. They are attached to such instruments, and used to magnify whatever object is pointed at.
General relativity is what Albert Einstein theorized in 1916, which describes that gravitation also affects the shape of space and flow of time. It proposed that the bigger the matter, the more it causes the space to curve.
