Nuclear Fallout
2013-04-01 10:26:30

Nuclear fallout, or just simply fallout, known also as Black Rain, is the residual radioactive material that is propelled into the upper atmosphere after a nuclear black or a nuclear reaction that is conducted in an unshielded facility. It is so called because it "fall out" of the sky after the explosion and the shock wave have passed. It most commonly refers to the radioactive dust and ash that is created when a nuclear weapon explodes, but such dust can also come from a damaged nuclear...

Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

Image Caption: NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 56,000 light-years in diameter and approximately 60 million light-years distant. Credit: NASA/ESA/Wikipedia What is Astrophysics? For much of the modern age the term Astrophysics has been used synonymously with Astronomy. This interchange is so common that many textbooks even offer the two as having the same meaning. However, from a strictly historical perspective there are differences...

Basic Ocean Terms
2013-02-05 12:52:11

Image Credit: Meteorologist Joshua Kelly When meteorologists are forecasting for ocean-going vessels, there are a few terms that we need to understand. The first term is wavelength. Wavelength is defined as the distance between two crests or between two troughs as seen in the image above. The example above highlights the crest to crest concept of wavelength. The next term that we use is wave height, and to determine this, we first must look at the wave when it passes our station. When...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...
