Look at the pictures of the Webb and the Spitzer telescope, which is already “retired”

All four science instruments on NASA's James Webb Space Telescope have achieved "perfect alignment"

ahead of the telescope's official debut this summer. Representatives of the project announced this at a press teleconference.

“I am pleased to report that the telescope has been adjustedcompleted with performance even better than we expected,” said Michael McElwain, the James Webb Space Telescope project scientist at NASA's Goddard Space Flight Center in Maryland, CBS News reports. — Basically, we have achieved the ideal setup of the telescope. Nothing will significantly improve our scientific results.”

To illustrate the readiness of the telescope,NASA shared a teaser image taken by the Webb Mid-Infrared Instrument, or MIRI (Mid-Infrared Instrument). The new image shows a side-by-side comparison of observations of the Milky Way's neighboring galaxy. One half shows a photograph taken by the Webb telescope, and the other half shows the same galaxy taken by the now retired Spitzer Space Telescope.

While the Spitzer image showsSeven blurry nearby stars in the Large Magellanic Cloud, Webb showed not only the same stars in sharp detail, but also thin clouds of interstellar gas, as well as hundreds of background stars and galaxies.

According to NASA, with the instruments configuredThe Webb telescope is awaiting final instrument calibration before it officially begins studying distant stars this summer. In July, the telescope will share its first set of science images.
