The Hubble Telescope and Spectroscopy

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

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

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 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

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

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

  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

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

Blog 3-Spectroscopy

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

Color in the Universe

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
