Tour de Light

Posted on February 13, 2015 by christophermfitzgerald

If you’re like me, when you think of light you think of the visible light spectrum, the colors of the rainbow. In reality light is much more than what we can see with our eyes, the spectrum extends far in … Continue reading → Continue reading →

Smiling Galaxy Cluster Found in Space!

Posted on February 13, 2015 by agiantchicken

That’s some intense gravitation lensing! A cluster of galaxies was recently discovered by the Hubble Telescope (AKA, uber relevant to class!) that appears to take on the shape of a bright smiling face. The galaxy cluster, known as SDSS J1038+4849, recently had the above picture taken by said telescope. While it may appear to us that […] Continue reading →

Radio Telescopes: Like Car Radios, but Bigger

Posted on February 13, 2015 by alyssasolarblog

When we think “telescope”, we picture peering through a viewfinder or viewing images of the stars. However, visible light is only a small part of the electromagnetic spectrum; we can learn much about our galaxy by viewing visible light’s less frequent older brother, the radio wave. Radio telescopes are the technological descendants of actual radios (like … Continue reading Radio Telescopes: Like Car Radios, but Bigger → Continue reading →

Circadian Rhythms and the Length of the Day

Posted on February 13, 2015 by alyssasolarblog

We learned in class that the earth’s day is always getting longer: that is, the attraction of the moon’s gravity pulls angular momentum from the earth, slowing down its rotation. On the flip side, the earth’s day used to be much shorter. Evidence from ancient corals indicate that the year was once 385 days long, meaning that … Continue reading Circadian Rhythms and the Length of the Day → Continue reading →
