Atmosphere Atmospheric Science

The Atmosphere Of The Earth: An Introduction

The atmosphere of Earth is the layer of gases, commonly known as air, that surrounds the planet Earth and is retained by Earth’s gravity. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth’s surface, absorbing ultraviolet solar radiation, warming the…

Messier 8 Lagoon Nebula

Messier 8, the Lagoon Nebula is a wonderful target for observers and photographers alike. Being one of only two star-forming nebulae faintly visible to the eye from mid-northern latitudes, M8 is a wonderful sight to see. Although…


Focal Reducer

Focal Reducer

A focal reducer, otherwise known as a telecompressor, is an optical element used to reduce focal length, increase lens speed, and in some instances improve optical transfer function performance. Although the popular applications include photography, videography, and astrophotography, we will be focusing on the…


Gravitational Waves

Gravitational Waves: An Introduction

Gravitational Waves can be defined as disturbances in the curvature of spacetime, generated by accelerated masses, that propagate as waves outward from their source at the speed of light. This means that gravitational waves transport energy as gravitational radiation, which is…

Sun Spot

Sun Spots

What are Sun Spots Sun spots are temporary phenomena on the photosphere of the Sun which appear as dark spots on the surface. These spots are easily identifiable as they are darker than the surrounding…


Gravity Assist

Gravity Assist: The Basics

In orbital mechanics and aerospace engineering, a gravity assist is the use of the relative movement and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft, typically to save propellant and reduce expense. The origins of a gravity assist can trace its origins to the…


Atmosphere Atmospheric Science

Atmospheric Science

Atmospheric science is the study of the Earth’s atmosphere and its various inner-working physical processes. The field of atmospheric science has since been extended to the field of planetary science and the study of the atmospheres of the planets and natural satellites of the solar…
