OUR James Webb Space Telescope (JWST) there is good, or rather great news for earthlings. The last instrument to be calibrated finally began to operate near absolute zero. Wherein James Webb is running as scheduled and there are a few more tests to run before observations can begin.

A small temperature for the device and cold sweat for scientists

After years of development, procrastination, and a $10 billion investment, each major stage of the project is, pardon the pun, butterflies in the stomach and makes participants sweat at every millimeter of advanced stages. The completed new and final stage will allow James Webb detect infrared radiation from space objects. The device is in working order Middle infrared instrument (MIRI).

If you don’t like the cold, say thank you for not MIRI. It operates at a temperature of 7 degrees Kelvin (the main measurement used in the scientific field). In degrees Celsius, this is equivalent to -266º. Almost like swimming in the dead of winter. But there is still some time before the release. JWST start your observations. team Telescope will capture more images of stars to check calibration MIRI. Meanwhile, James Webb will continue to calibrate its mirrors and three more instruments. According to forecasts, everything will be ready in June.

James Webb: years from production to release

project James Webb telescope was developed National Aeronautics and Space Administration (NASA) in collaboration with European and Canadian space agencies. It was originally scheduled to launch in 2007. But some problems delayed the launch of the model, one of them was the high cost of production of the James Webb telescope, which was increasing more and more, and, back in 2005, forced Engineers to rethink the original design.

In 2016, the telescope was declared ready, but its project was again put on hold due to construction difficulties and remained so until 2019, when it was finally assembled. However, due to the COVID-19 pandemic, there have been more delays until NASA finally scheduled for release on December 18, 2021.

With it, researchers will be able to observe even more things from space, being able to see some of the oldest galaxies in the universe and other celestial bodies such as black holes.
