Optical Telescopes are able to collect significantly more light than the human eye, the larger they are the more light they are able to capture, which then forms and image of distant objects for the eye to see. When we turn a telescope to the night sky an optical telescope gathers and focuses light allowing […]
Telescopes
It is essentially on telescopes that modern astronomy is founded. In the ages before this technology was invented, all astronomy was naked-eye astronomy which means that we were vastly limited by what our eyes can see — even with the assistance of the first telescopes just over 400 years ago — and most of what […]
The Difference Between Mass and Weight
The difference between mass and weight is that they are quantities which ultimately mean different things, are measured differently, relate to different physical quantities and relationships. They are related to one another, sure. However, they are not the same. Our weight is the amount of force that the Earth exerts on an object, whereas the […]
Black Hole Accretion Disk
A Black Hole Accretion Disk is a massive disk composed of superheated gas, dust, and plasma that rotates around a black hole in an orbital pathway just beyond the event horizon — the spherical region around a black hole singularity inside of which the gravitational force exerted by the black hole is so great that […]
