The James Webb Space Telescope is a space telescope operated by NASA and designed primarily to conduct infrared astronomy. Launched in December 2021, the spacecraft has been in a halo orbit around the second Sun–Earth Lagrange point (L 2 ), about 1.5 million kilometers (900,000 mi) from Earth, since January 2022.
The HP LP2065 20 inch (50.8 cm) monitor has an actual viewable area of 20.1 inch (51 cm). [ 13 ] In a more significant case, some monitors such as the Dell UltraSharp UP3216Q (3840×2160 px) are advertised as a 32-inch "class" monitor (137.68 PPI), but the actual viewing area diagonal is 31.5 inches, making the true PPI 139.87.

This "inch" system gives a result approximately 1.5 times the length of the diagonal of the sensor. This " optical format " measure goes back to the way image sizes of video cameras used until the late 1980s were expressed, referring to the outside diameter of the glass envelope of the video camera tube .
Space Shuttle Discovery as it approaches the International Space Station during the STS-114 on 28 July 2005. The Space Shuttle thermal protection system (TPS) is the barrier that protected the Space Shuttle Orbiter during the extreme 1,650 °C (3,000 °F) heat of atmospheric reentry. A secondary goal was to protect from the heat and cold of ...
