When you hear of the planck scale, you’ll have to think small and hot but no, I wasn’t referring to red and green jalapeño peppers. I am, in fact, talking about this theory in physics that is the subject of much debate among physicists both young and old.
In astronomy, the term protoplanetary disk refers to the circumstellar disk of space matter, composing of space dust, different types of gas, specifically the types of nitrogen, hydrogen or other elemental gas. It is said that this type of astronomical marvel is the basis or essential structure for forming planetary systems, and eventually galaxies.

In astronomy, the term protoplanet illustrates a type of planet, included in the planet formation theory. This term is defined as the larger planetary embryos within protoplanetary discs that may have gone through the process of internal melting to produce a different planetary interior. It is also believed that these types of celestial bodies are
The position angle refers to the relative measurement of the secondary object from the primary one on the same celestial sphere, often used to measure and observe binary or double stars. The position angle is measured in degrees in a counter clockwise direction starting from the north celestial pole. It is usually abbreviated to PA.
One theory of planetary formation cites small celestial objects known as planetesimals to be the forbearers of planets. They are formed by the combination of dust, rock and other materials moving within the solar nebula. Through a process called ‘accretion’, these small microscopic particles collide and merge to form larger bodies measuring up to a
A planisphere is a must-have device for people who love to stargaze at night. This is a representation of the celestial sphere on a flat plane that can be adjusted around a common pivot to show which stars would be visible in the night sky at any given time and date. This is an especially
The plasmasphere is that region of dense, cold plasma surrounding the Earth. It is a part of the plasma-containing magnetosphere and is located just outside the upper ionosphere, extending to about 8000 to 25,000 miles into space. This donut-shaped volt of energy around our planet is the result of a process jumpstarted by the Sun’s
A polar ice cap is that region at either poles of a planet or natural satellite that is permanently covered in ice. It is different from an ice cap in that there are no specifications on the size or composition of a body of ice for it to be considered a polar ice cap. Whereas
The Poynting-Robertson effect is the radiation pressure produced by the Sun’s rays striking the small particles orbiting it, causing them to slow down and spiral towards the gigantic ball of fire. More specifically, this refers to the Sun’s radiation and gravity working together to form an interstellar giant vacuum that sucks in tons and tons

The Sun’s radiation emits tons and tons of energy. This energy is used up by living things to sustain life and survive. The Sun’s radiation is continuously being utilized as green and clean technology to supply electricity in remote areas and to save the environment by minimizing the production of greenhouse gases. With the Sun’s
