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 […]
Stars and celestial objects are far from the Earth. Unlike travelling by land which can be easily approximated by measuring distances in kilometers or miles, celestial objects cover a great distance away from the Earth. Another unit of measurement is used to quantify this huge distance which cannot be simply represented by the use of
Light pollution is also referred to as luminous pollution. It is the excessive production of man made light. It is also defined as the negative consequence of too much artificial light, which includes the clutter of light. Energy waste is also associated with such excessive production of artificial light.
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
Photo by: Basilicofresco Creative Commons The L chondrite, also known as the L type of ordinary chondrites, is very common in spite of its relatively unknown status. They account for around 30 % of the categorized type of meteor, and around 40 % of the normal kind of chondrites.
Light-gathering power is a way to measure the performance and effectiveness of a telescope that is proportionate to the square root of the size of the aperture. For instance, a telescope that possesses more than two times its diameter has the potential to collect about four times as many light.

Libration refers to the movement of orbiting bodies in relation to one another. For instance, the movement of the Moon Relative to the Earth is an example of a Libration. One of the common examples of Libration is Lunar libration. The moon consists of a singular hemisphere, which faces the earth. Over time more of
Photo by: Archaeodontosaurus Creative Commons Tremolite is a member of a group of silicate minerals containing molecules of Calcium, Magnesium, Silicon and Oxygen. It is formed by the metamorphism of sediments with high amounts of dolomite and quartz. Its color ranges from creamy white to dark green, depending on magnesium or iron content. In fact,
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
Ultraviolet light is a type of light or electromagnetic radiation that has a shorter wavelength than that of visible light. The primary source of ultraviolet light is the sun; it can also be found in electric arcs and in specialized lights. Far ultraviolet on the other hand is ultraviolet light with a wavelength range of
