 (FILES) This handout image released by NASA on July 12, 2022, shows the bright star at the center of NGC 3132, while prominent when viewed by the James Webb Space Telescope (JWST) in near-infrared light, plays a supporting role in sculpting the surrounding nebula. A second star, barely visible at lower left along one of the bright star�s diffraction spikes, is the nebula�s source. It has ejected at least eight layers of gas and dust over thousands of years. - The JWST is the most powerful telescope launched into space and it reached its final orbit around the sun, approximately 930,000 miles from Earths orbit, in January, 2022. The technological improvements of the JWST and distance from the sun will allow scientists to see much deeper into our universe with greater detail.
