Welcome to the introduction to the topic of neutron stars. This article will be more of a general overview to provide a sense of what these objects are, how they form, and where they reside….
A gamma-ray burst, often abbreviated as GRB, is extremely energetic explosion that is observed in distant galaxies and are the brightest electromagnetic events in the universe. The length of a GRB can vary, with some…
In positional astronomy, two astronomical objects are said to be in opposition when they are on opposite sides of the celestial sphere, as observed from a given body (usually Earth). A planet, asteroid, or comet…
Previously we have talked about the different galaxy types, and it got us thinking about structures that could be larger than the single galaxy? The answer is galaxy clusters and superclusters. Galaxy Clusters A galaxy…
In the standard model of cosmology, the total mass–energy of the universe is said to contain 5% of ordinary matter and energy, 27% of dark matter, and 68% of what is known as dark energy. This article will only touch the surface of…
In observational astronomy, a double star or visual double is a pair of stars that appear close to each other as viewed from Earth, especially with the aid of optical telescopes. The first double stars…

The technical definition of space weather can be said to be a branch of space physics and aeronomy concerned with the time varying conditions within the Solar System. It is worth noting that these features are distinct from but…
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…
