Quote from: NASAThe primary mirror segments and secondary mirror are moved by six actuators that are attached to the back of each mirror piece. The primary mirror segments also have an additional actuator at its center that adjusts its curvature.
QuoteEach of the 18 segments of the primary mirror is plated in a shiny, but ultra thin, layer of gold. If left in launch position, they would act as individual telescopes with images that would be fuzzy and unclear. Once aligned, the mirror segments will act as one giant mirror 21.3 feet (6.5 meters) across, the largest ever in space. NASA has estimated that it could take up to 120 days after launch for Webb's mirror alignment work to be complete. The first photos from Webb are not expected until about five months after launch once commissioning ends.

QuoteThe photograph was made with light emitted by different elements in the cloud and appears as a different color in the composite image: green for hydrogen, red for singly ionized sulfur and blue for double-ionized oxygen atoms.
QuoteWe have an "SHO" image, or an image that blocks out all signal except for very precise lines of emission. In this case, SII, Hα, and OIII. These wavelengths are typically assigned colors in post processing, where SII = Red, Hα = Green, and OIII = Blue. In actuality, this is where they actually are in the "visible" color spectrum. Since Hydrogen is by far the dominant gas in most emission nebulae (see the image on the right being nothing but red), we get mostly nothing but green in an SHO image to begin with. After subtracting the green though, we are left only with how the Hα interacts with the SII and the OIII giving us a nice contrasting gold and blue color that shows the complexity of the nebula's composition.

Quote from: Dex Sawash on January 11, 2022, 12:22:18 PMWhat sort of space filth have the censored at the top right?
QuoteToday, at 2 p.m. EST, Webb fired its onboard thrusters for nearly five minutes (297 seconds) to complete the final postlaunch course correction to Webb's trajectory. This mid-course correction burn inserted Webb toward its final orbit around the second Sun-Earth Lagrange point, or L2, nearly 1 million miles away from the Earth.The final mid-course burn added only about 3.6 miles per hour (1.6 meters per second) – a mere walking pace – to Webb's speed, which was all that was needed to send it to its preferred "halo" orbit around the L2 point.
