With NASA contributions, the mission will complement dark energy studies to be made by the agency’s upcoming Nancy Grace Roman Space Telescope. The Euclid mission, led by ESA (the European Space Agency) with contributions from NASA, has released five new images that showcase the space telescope’s ability to explore two large-scale cosmic mysteries: dark matter … Read more
Around this same time in history, astronomer Vesto Slipher observed spiral galaxies using his telescope’s spectrograph, a device that splits light into the colors that make it up, much like the way a prism splits light into a rainbow. He used the spectrograph, a relatively recent invention at the time, to see the different wavelengths … Read more
