Color in the Universe

Posted on April 26, 2016 by imanig625

The pale blue dot is Earth, but what if Earth is the only planet that gives off that specific color? While other exoplanets can and have mimicked the pale blue color, a broader portion of Earth’s overall spectrum shows a rather subtle signature that can only be attributed to life. Earth’s blue color comes from the… Continue reading →

Spectroscopy and the identity of elements

Posted on February 14, 2015 by ctogrye

Hey Everyone, Today I am going to discuss the details of spectroscopy which explain why different atoms and molecules have different characteristic emission and absorption spectrum. The reason for this unique patterns lies with the the atom’s (or molecule’s) electron energy levels. Each atom and molecule has a unique separation of electron energy levels which […] Continue reading →

I always wondered how we were able to determine what chemicals are present in other stars in outer space. This video excellently and concisely teaches the basics behind studying this in terms of spectroscopy. Naturally, light is important in our viewing of the stars, but I never considered that the way different elements bend light … Continue reading Spectroscopy → Continue reading →

HINS-Light > Purell?

Posted on February 18, 2013 by burnspress

Spectroscopy refers to the interactions between matter and light, or radiated energy, and the dispersion of an object’s light into its various wavelengths (i.e. colors). Dissecting an object’s light through spectroscopy helps modern astronomers determine the physical properties of stars. However, the study of light aids more than just astronomers in scientific battles today. New […] Continue reading →

The Art of Spectroscopy

Posted on February 13, 2013 by staunesm

To talk about spectroscopy, we first need to talk about its origins.  Spectroscopy was first discovered in the late 17th century by the late and great Sir Isaac Newton.  Although only the bare bones, Newton founded the idea that refracting … Continue reading → Continue reading →
