Astronomers show how James Webb is better than other space telescopes

The James Webb Space Telescope, located 1.5 million kilometers from Earth, was designed to observe the youthful years of our universe. The telescope looks up at the sky with the help of infrared sensors, which, as can be seen from the first experimental images, are stunning images in terms of details. How good are these pictures? Clearly shown Astronomers have compared the image of “James Webb” to two images of the past year.

Experimental image from the James Webb Telescope (pictured right) Received From a nearby MIRI camera in the infrared range (operating at wavelengths ranging from 4.6 to 28.6 microns). The image shows the giant Magellanic cloud, a satellite of our Milky Way galaxy. Pictured above is a 40cm Wide Infrared Survey Explorer (WISE) space telescope launched in 2009 and the 85cm Spitzer Space Telescope launched into orbit in 2003, photographing the same area from left to right. The sky.

The James Webb telescope has an aperture of 6.5 meters, which is many times larger than previous infrared telescopes. The difference, as they say, is visible to the naked eye. The James Webb crew itself was amazed at the resolution and clarity of the images, which exceeded all wild expectations. This is true because the optical capabilities of the telescope can only be fully understood in real life. Although telescope vacuum and temperature tests were performed on the ground, it was almost impossible to exclude gravity and vibration from the experiments. But in space, “James Webb” revealed and increased its full potential.

The first scientific images of “James Webb” will be available from July this year. Now, the telescope team has begun commissioning the telescope’s scientific instruments – two cameras and two spectrometers. NASA will set aside a special briefing on May 9 for this chapter on the establishment of the Observatory, during which it will share action plans.
