Pleiades emission spectra
Pleiades emission spectra. These multicoloured bands are obtained by recording what wavelengths of light (each seen as a different colour) are emitted by each star in the open cluster Pleiades. White light is a combination of a range of light wavelengths and can be separated into its components using a prism. The dark vertical lines within these bands (called Fraunhofer absorption lines) show that some wavelengths of light emitted outwards from the hot interior of the star were absorbed by atoms within the cool gases that make up the stars outer layer

EDITORS COMMENTS
This print showcases the mesmerizing Pleiades emission spectra, revealing a stunning array of multicolored bands. Each band represents the specific wavelengths of light emitted by individual stars within the open cluster Pleiades. By employing a prism, white light - composed of various wavelengths - can be separated into its distinct components, allowing us to witness this breathtaking cosmic display. However, what makes this image even more intriguing are the dark vertical lines that traverse these vibrant bands. Known as Fraunhofer absorption lines, they signify certain wavelengths of light emitted from the star's scorching core being absorbed by atoms present in its cooler outer layer comprised of gases. These absorption lines offer valuable insights into the composition and characteristics of these celestial bodies. The photograph serves as a testament to humanity's relentless pursuit of knowledge about our universe and its countless wonders. It encapsulates key concepts from astrophysics and cosmology while highlighting the intricate interplay between stellar emissions and their surroundings. With its striking visual appeal and scientific significance, this print is an exquisite addition for any space enthusiast or admirer of astronomical phenomena. Courtesy of Science Photo Library, it invites us to delve deeper into the realms beyond our own planet and explore the mysteries hidden within starlight itself.
