Compare and contrast: the Milky Way galaxy and the Andromeda galaxy
By: Andrew Moran
The Milky Way and Andromeda (M31) galaxies made news in May when NASA officials confirmed that the two are headed for a cosmic collision within the next four billion years – an additional two for it to merge and then another two billion for when...
NASA Spitzer space telescope spots watery super-earth 55 Cancri e
By: Jose Juan Gutierrez
NASA’s Spitzer Space Telescope detected light emanating from a super Earth-like planet (55 Cancri e). Planet 55 Cancri e falls into a type of exoplanets designated as super-Earth planets, which are more massive than the Earth. 55 Cancri e is about twice the size...

Astronomers and physicists alike have long speculated that other stars must have planets that orbit them just as they do in this solar system. It is quite exciting to realize that such a consensus has turned out to be true. In the past couple of...
What is a gravitational keyhole?
By: Jose Juan Gutierrez
A gravitational keyhole, also known as resonance keyhole, is a small section in a planet’s gravitational region where gravity would alter the orbit of a passing asteroid, causing that asteroid to change its path on a future orbital approach. The keyhole refers to the...

Quite simply, astrometry is a field within astronomy that deals with the positions and movements of celestial bodies. Emphasis is placed on accurately determining the movement of stars and other objects. Astrometry uses this information to provide information about how the bodies in our...
Contacting Aliens
By: Robert Hoglund
As of now, we have no evidence that alien civilizations exist. However, we occupy and observe a very small part of a huge, perhaps infinitely large universe. I will tackle the question at hand supposing that we have found evidence of an alien civilization already...
What is cold welding?
By: Jose Juan Gutierrez
Cold welding involves joining two pieces of metal together using intense pressure and without the application of heat. Cold welding is a solid state process in which pressure at ambient temperature initiates coalescence between two metals. The pressure produces deformation until a desired state is...
What is cold welding?
By: Olivia Kay
Cold welding is the process of bonding two objects together without heat and without any melting taking place. It is totally opposite of traditional welding as the two objects do not change state as they combine into one. Objects that are cold welded combine through...
What is the Kuiper Belt?
By: Jose Juan Gutierrez
The Kuiper belt is a region of the solar system that lies further beyond the orbit of Neptune. The Kuiper belt is populated by objects, including asteroids, comets and other ice dwarfs. The name with which these objects are collectively known is Kuiper belt objects...

Ever since Galileo confirmed the earth was not the center of the universe, man has been pushing the limits of knowledge to discover more about the universe and in particular the solar system. With the technological advancements of the past century, man has been able...
