NASA's Webb and Hubble Reveal Cosmic Secrets in Stunning Galaxy Images
The James Webb Space Telescope and the Hubble Space Telescope have captured images of the spiral galaxy NGC 2090, showcasing the complementary capabilities of both telescopes. Webb's instruments reveal the galaxy's spiral arms and swirling gas in infrared, highlighting young stars and polycyclic aromatic hydrocarbons, while Hubble's optical view shows the galaxy's dust and star formations. These observations aid in studying stellar evolution and the universe's expansion rate through Cepheid variable stars.
