The James Webb Telescope makes unprecedented images of the Great Magellanic Cloud

As reported by Watch DigitalThe James Webb Space Telescope (JWST) is one step away from a successful start-up, and the task force is making the final adjustments to the equipment that includes it.

Some test photos have been sampled and released by the team during work over the past few months. Now, the main goal has been to focus: Big Magellanic Cloud.


According to Scott Friedman, JWST Chief Commissioning Scientist at NASA’s Space Science Telescope Institute, the main purpose of the data from our galactic near-field is to measure the impact and improve the sharpness of images.

Using its most advanced cooling device, the Mid-Infrared Instrument (MIRI), the next camera could capture large Magellanic clouds with the sharpest vision ever seen in the history of stellar observations, proves its excellent performance.

The new MIRI diagram shows the chemistry of interstellar gas galaxies in optimal expansion, with the emission of carbon and hydrogen molecules called “polycyclic aromatic hydrocarbons,” considered to be some of the building blocks blocks of life.

At a news conference broadcast on the Internet on Monday, a team of scientists said that the potential of these images is crucial to helping the glasses to understand that day. old and protoplanetary process design.

“This is one of the best examples of what Webb will bring to us in the coming years,” said Chris Evans, an analyst at the European Space Agency (ESA), a partner in the project. work.

“We have done a lot of research on the formation of stars and planets in our galaxy, but here we are looking at it in the Magellanic Clouds, tiny galaxies, which are very rare. change is more than our Milky Way, ”Evans added. “So this gives us a chance to see the process of the stars and the planets created in a different environment of our own galaxy.”

Detailed information by James Webb telescope allows for the unprecedented of galaxy processes

For comparison, the team published images with one of the same targets led by the resting Spitzer Space Telescope – the leader, in his day, in the creation of high-resolution images of the Earth. While Webb took its picture at 7.7 microns, Spitzer recorded it at 8.0 microns.

“Spitzer has done amazing things,” Evans said. become in general terms. “

According to him, Webb detailed and close proximity will provide “an incredible picture of the process in a different galaxy for the first time, removing dust.”

“We are using mid-infrared to look through objects that would limit the visibility of the visible wavelengths,” he explained.

The new spacecraft has a larger face, improved equipment, and a better probe than that of Spitzer, which used to work in orbit Earth, unlike Webb’s orbit. Second Lagrange Point (L2) between Earth and Earth. The sun, about 1.5 million km away. According to its researchers, these conditions would allow the laboratory to access infrared data more clearly than its predecessors.

Knowing the location of stars in the Big Magellanic Cloud is an important asset for astronomers, according to Michael McElwain, JWST project scientist at NASA’s Goddard Space Flight Center.

“We can use them for astrometric calibrations,” he explains, adding that this is important for measuring instruments. “Of course, these pictures are also great.”

In the near future, the task force will also test the laboratory’s ability to track solar objects, such as planets, satellites, rings, asteroids and comets. Scholars will focus on ensuring that Webb can do this correctly, because it’s unique to the stars.

“We will also measure the change in the lens difference as we point it at different locations,” Evans said. To do this, Webb is conducting a thermal stability measure, which oscillates at a position where it receives more or less sunlight.

Although the team has not yet announced what goal it will focus on for the first time when its experiment is complete, the researchers said the lab was scheduled to begin its study at for June or July.
