James Webb Space Telescope: a new image – 06 Jan. 2022
After several cloudy nights, we had another glimpse of the James Webb Space Telescope. Here it is our latest image.
The image above comes from a single 180-second exposure, unfiltered, remotely collected with the “Elena” (PlaneWave 17″+Paramount ME+SBIG STL-6303E) robotic unit available at the Virtual Telescope Project. Our robotic telescope tracked the apparent motion of the James Webb Space Telescope (JWST), which is marked by an arrow in the center.
While constantly increasing its distance from us, the space telescope is still easy to spot with our instruments, as it deployed its sunshield, making it much brighter. In addition, at the imaging time the JSWT had already completed the deployment of the Secondary Mirror Support Structure, so we can now really call it “telescope”!
At the imaging time, JWST was at about 975.000 km from us (almost 2.5 times the average lunar distance); its final destination is the L2 (2nd) Lagrangian point of the Earth-Sun system at 1.5 millions of km from us. As seen from the Sun, that L2 point is directly behind the Earth.
