![]() However, Hubble is only so powerful and is limited by its 2.4-meter mirror. Hubble’s 1995 deep field is among the most popular images of our universe ever created, and subsequent deep fields have allowed scientists to peer deeper and deeper into our universe by increasing exposure times. Within the fields of astrophysics and cosmology, one question has existed in the minds of scientists for centuries - when did our universe form, and how did the first stars and galaxies form? Throughout the last few decades, several telescopes, such as the Hubble Space Telescope and ground-based observatories, have been used to create massive mosaics of portions of the sky called deep fields. ![]() JADES Data Reveals 45,000 Galaxies, Unveils Early Universe’s Secrets Behind the dust within the galaxy’s bars were hundreds of gas bubbles where young, hot stars are forming and growing. ![]() The JWST advanced deep extragalactic survey (JADES) utilized Webb’s incredible deep-field surveying abilities to create a deep field that shows over 45,000 galaxies and uncovers some of the secrets of the early universe.Īnother team took advantage of Webb’s immense sensitivity to infrared light to peer behind the thick dust within the bars of a barred spiral galaxy. With help from the joint NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope (JWST), scientists are peering deep into the universe and uncovering secrets that were previously hidden from visible and X-ray telescopes.
