Blog 3 – Electromagnetic Spectrum

Posted on February 16, 2017 by johnjohnb4

For this blog I thought I would further look into the electromagnetic spectrum.  As in the picture below, we can see that the light that humans see is only a small portion of the full spectrum of light, collectively known as the electromagnetic spectrum.  Light itself is technically radiation, but only certain types of light […] Continue reading →

Blog 1: The Speed of Light And Refractive Index

Posted on February 15, 2017 by mchastr2110

Light travels at a velocity incredibly difficult for us to comprehend other then as just a very, very large number. To be exact, light travels at a constant velocity of 299,792,458 m/s within a vacuum. This is not the same for light traveling through other conditions. When light does travel through things other then a … Continue reading Blog 1: The Speed of Light And Refractive Index Continue reading →

The EM Spectrum

Posted on February 14, 2017 by julianchase

When most people think of the word “light” they are probably talking about visible light, but the electromagnetic spectrum is much bigger and more diverse than that. Visible light is actually a very small part of the electromagnetic spectrum. Lets break down the spectrum in terms of wavelength. Visible light has a wavelength of 390 … Continue reading “The EM Spectrum” Continue reading →

Rogue Radio Burst Leads to Discovery of Billion-Year-Old Galaxy

Posted on February 14, 2017 by njelinek425

The detection of fast radio bursts, one of the universe’s most mysterious and rare occurrences, took place in early January of this year when signals from a dwarf galaxy over 2.5 billion light years away were first recorded. Fast radio bursts (FRBs) are an incredibly rare phenomenon usually occurring in a millisecond or so, each […] Continue reading →

The Invention of the Telescope

Posted on February 14, 2017 by pkunetz97

Galileo was the first astronomer to use a telescope to observe the moon, the phases of Venus, and the largest four moons of Jupiter. In fact, Galileo was the first astronomer to use a telescope for anything because he was the dude who invented it. He first heard about a dutch inventor who put curved […] Continue reading →

The Importance of Spectroscopy in Solar System Exploration

Posted on February 14, 2017 by njelinek425

While the very existence of visible light allows for the viewing of celestial bodies, not enough credit is oft given to the true capability of light’s full spectrum. Spectroscopy is an imaging and scientific method of measurement that involves the unique spectra that occur when light comes into contact with an object or substance of […] Continue reading →
