Spectroscopy

Posted on September 24, 2024 by Matthew Marcus

Blog #2 While the role of light in our everyday lives is to make color and form visible, by studying light with spectroscopy, we can learn a surprising amount about the object that produces a certain spectrum of wavelengths. In order to understand spectroscopy, first, we must understand what light physically is. Light is composed […] Continue reading →

Black Body Radiation, analyzing the Universe at Long Distance

Posted on February 12, 2023 by noahherrero

Illustration of Supermassive BlackHole Formation (An Ideal Black Body) from GOODS Source: X-ray: NASA/CXC/Scuola Normale Superiore/Pacucci, F. et al, Illustration: NASA/CXC/M. Weiss Optical: NASA/STScI; Celestial Bodies throughout the universe are extraordinarily far away, yet despite this we are able to describe these objects with precision. The reason this is possible is because the radiation of these […] Continue reading →

The Hubble Telescope and Spectroscopy

Posted on February 20, 2022 by josephmaquino9

When many people think about the Hubble Telescope, they tend to think of some of the most spectacular photos that it has captured over its five missions (with an example displayed in Figure 2). However, some people may fail to recognize the importance of the spectrographs that the Hubble Telescope produced and the valuable information […] Continue reading →

Evolution of Spectroscopy

Posted on February 28, 2021 by miichellewang

Spectroscopy describes the study of the interaction between matter and the wavelength of the light it produces, although this definition has been updated to include anything measured as a function of frequency or wavelength. Isaac Newton was one of the first people to demonstrate that light from the Sun could be scattered into a spectrumContinue reading “Evolution of Spectroscopy” Continue reading →

Spectroscopy and Stars

Posted on February 27, 2021 by christianc3

While it may seem impossible to be able to identify the types of elements that stars billions of light years away are made of, scientists discovered a way to do exactly that. In the 1850s, Kirchhoff and Bunsen managed to identify what the black lines in light spectra meant, and it allowed them to identifyContinue reading “Spectroscopy and Stars” Continue reading →

Spectroscopy

Posted on February 26, 2021 by Mykayla

Spectroscopy is the act of “fingerprinting” stars by observing their spectra. A spectrum is produced by filtering light through a prism, resulting in a rainbow of color. There are three different types of spectra: continuous, emission, and absorption. A continuous spectrum is produced when the light of a hot, dense object is directly filtered throughContinue reading “Spectroscopy” Continue reading →

The Importance of Spectroscopy

Posted on February 7, 2020 by emily

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 →

Light: It’s More than We Think

Posted on February 6, 2020 by Jonah

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 →

Don’t Take Light Lightly

Posted on February 12, 2018 by interplanetira

  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 →

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 →
