What is hydrazine? What is it and why haven’t you heard of it? It is an organic chemical compound that is odorless and flammable. It is a liquid that smells like ammonia since it is derived from the same industrial chemical processes; though the physical properties of this chemical is closer to water.

Over time though, the hydrogen at the core diminishes, thus preventing fusion. As the star begins to end, there will emerge a new source of hydrogen fuel which will
A Lenticular galaxy is basically a kind of galaxy which borders in between an elliptical and spiral galaxy when classified. They are shaped like a disk, and have almost no interstellar matter, and very little formation of stars. There are, however, remnants of small dust particles. A lot of aging stars are present in this
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
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
The universe is continuously being explored by astronomers and scientists. This exploration and research endeavors have led to the discovery of many other galaxies and celestial phenomena that had been unknown to us for many years. Now, the Milky Way galaxy, which is our galaxy, is now part of a Local Group, where about thirty

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
