The impact that spectroscopy and light has had on the world has not been recognized enough. The discovery of spectroscopy has allowed us to know so much more about astronomy and what makes up our universe. Spectroscopy is the investigation and measurement of spectra when matter interacts with electromagnetic radiation. In astronomy, we look atContinue reading “The Importance of Spectroscopy” Continue reading → Continue reading
Flip a switch. Turn a knob. Push a button. Look in the sky in the day or at night. Each of these actions will allow you to see light, and most people see light as nothing more than an illuminator. Its purpose in the field of astronomy is much more than illuminating the Universe forContinue reading “Light: It’s More than We Think” Continue reading → Continue reading
When you hear the word “light”, a few things might pop into your mind – the Sun, lightbulbs (or artificial lights in general), or maybe even the colors of the rainbow. What you probably don’t think about are the other forms of light on the Electromagnetic Spectrum. The fact of the matter is that […] Continue reading → Continue reading
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 → Continue reading
Spectroscopy is a scientific technique that “measures light that is emitted, absorbed, or scattered by materials and can be used to study, identify and quantify those materials” (Source). Therefore, spectroscopy can be used to provide invaluable information about different objects based on the light they emit and absorb (which is referred to as the emission…Continue reading → Continue reading
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 → Continue reading
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 → 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 → Continue reading
