“After all, galaxies don’t spring up from nothing, virtually overnight.” “However, logic dictates that at some point during the first few hundred million years, these familiar-looking objects must have come from somewhere and evolved,” Rieke said. So far, what scientists have observed from this time period looks similar to what we already understand. “We can currently see galaxies back to 500 million to 600 million years post-Big Bang, nearly 13 billion years ago,” said Marcia Rieke, a Regents Professor of Astronomy at the University of Arizona’s Steward Observatory and principal investigator for the Near Infrared Camera on the Webb telescope. The name of NASA's most powerful telescope is still controversial one month before its launch This is a great achievement and an inspiring image for the entire team," said Lee Feinberg, optical telescope element manager for Webb at NASA's Goddard Space Flight Center in Greenbelt, Maryland.įor more about this test: go./33XdiEa Chris Gunn/NASA "Deploying both wings of the telescope while part of the fully assembled observatory is another significant milestone showing Webb will deploy properly in space. Performed in early March, this test involved commanding the spacecraft's internal systems to fully extend and latch Webb's iconic 6.5 meter (21 feet 4-inch) primary mirror. In order to perform the groundbreaking science expected of Webb, its primary mirror needs to be so large that it cannot fit inside any rocket available in its fully extended form. In a recent test, NASA's James Webb Space Telescope fully deployed its primary mirror into the same configuration it will have when in space. NASA's James Webb Space Telescope Full Mirror Deployment a Success Its capabilities will enable the observatory to answer questions about our own solar system and investigate faint signals from the first galaxies formed 13.5 billion years ago. The Webb telescope will look at every phase of cosmic history, including the first glows after the Big Bang that created our universe and the formation of the galaxies, stars and planets that fill it today. Webb will act as an infrared sleuth, detecting light that is invisible to us and revealing otherwise hidden regions of space. In addition to investigating the wealth of planets outside of our solar system, the observatory will peer back to some of the earliest galaxies that formed after the Big Bang and the very structure of the universe itself. The telescope is expected to launch Saturday morning from French Guiana and live coverage will be available on NASA’s website beginning at 6 a.m. The James Webb Space Telescope will be the premier space observatory of the next decade when it launches Saturday. We’re about to have eyes on the invisible side of space.
