- Background: Introduction to Spectroscopy - Imagine the Universe!
Spectroscopy is a complex art - but it can be very useful in helping scientists understand how an object like a black hole, neutron star, or active galaxy is producing light, how fast it is moving, and even what elements it is made of A spectrum is simply a chart or a graph that shows the intensity of light being emitted over a range of energies Spectra can be produced for any energy of

Spectroscopy can be very useful in helping scientists understand how an object like a black hole, neutron star, or active galaxy produces light, how fast it is moving, and what elements it is composed of Spectra can be produced for any energy of light, from low-energy radio waves to very high-energy gamma rays

spectroscopy The study of spectral lines from different atoms and molecules Spectroscopy is an important part of studying the chemistry that goes on in stars and in interstellar clouds spectrum (plural: spectra) A plot of the intensity of light at different frequencies Or the distribution of wavelengths and frequencies Tell me more about
- X-ray Spectroscopy - Imagine the Universe!
X-ray Spectroscopy A Series of Lesson Plans by Allie Hajian and Maggie Masetti (NASA GSFC) Rick Fowler (Crossland High School) Angela Page (Hyattsville Elementary School) Objectives - Students will read and write about the chemistry and spectroscopy of stars and supernova remnants, as well as understand their relevance and impact on human life
- Supernova Chemistry Lesson Plan - Imagine the Universe!
Supernova Chemistry Suggested grade levels: 9-12 Estimated class time: 2-3 class periods Lesson plan by Jane Mahon and Ron Dodson of Hoover High School in Hoover, Alabama Summary This lesson gives the student an opportunity to identify elements by using spectroscopy and to relate this activity to astrophysics Students will use spectrometers to measure the spectra of various light sources at

With that discovery, scientists had the means to determine the chemical composition of stars through spectroscopy Stars aren't the only objects for which we can identify chemical elements Any spectrum from any object allows us to look for the signatures of elements This includes nebula, supernova remnants and galaxies

Advanced Basic Spectral Analysis In a star, there are many elements present We can tell which ones are there by looking at the spectrum of the star The science of spectroscopy is quite sophisticated From spectral lines astronomers can determine not only the element, but the temperature and density of that element in the star The lines can also tell us about the magnetic field of the star
