Last Monday the world was surprised when the United States Space Agency (NASA) revealed deep space images caught by him james webb telescope.
nebula images Carina Nebula -reminiscent of the album covers of the band Yes- and the clear infrared photograph of the galaxy cluster SMACS 0723 – which far exceeds the most daring galactic fantasies of a Star Wars fan – began to spread like a new milestone in space exploration.
However, to get to this point it was necessary to carry out several tests and calibrate the telescope. that’s where it comes in Jupiter, the largest planet in the solar system, whose images were released by NASA.
The images captured before the official operation of the James Weeb Telescope They allow us to appreciate the spectra of several asteroids and the moons of the colossal planet, which has a radius of 71,492 kilometers, 11.2 times larger than that of Earth.
“Together with images released the other day, these images of Jupiter demonstrate the power of what Webb can capture, from the most distant galaxies to the planets in our cosmic backyard,” said Bryan Holler, a scientist at the Jupiter Institute of Sciences. Baltimore Space Telescopes, who helped plan this work.
In the photographs published by NASA on its blog, it is clearly visible the moon Europa, which according to studies could harbor an ocean under its thick ice crust. Even the shadow of the moon is reflected to the left of the enormous Red Eye of Jupiter.
You can also see the moons El ser Y metis.
The importance of images is that they are proof that Webb can observe satellites and rings near objects as bright as Jupiter, Saturn and Marswhich will allow scientists to even see plumes of steam, such as those given off by Jupiter’s moons Europa and Enceladus, NASA said.
The tests were aimed at seeing how well the telescope could pick up celestial bodies in motion, even with massive, luminous objects behind them.
With a movement of translation that takes 12 Earthling years, Jupiter was the ideal target, as it is one of the slowest planets in the solar system.which also made it easier to correctly calibrate the telescope, NASA noted.
Meanwhile, another document from NASA, the European Space Agency and the Canadian Space Agency explains that Jupiter was used to calibrate the NIRcam, one of the infrared cameras that the James Webb telescope has.
“The idea was to test the telescope’s ability to take moving images, as occurs with Jupiter’s natural satellites,” reads the document “Characterizing the performance science of the James Webb Space Telescope since its commissioning.”
