'We now know with certainty that it will.' 'JWST was envisioned 'to enable fundamental breakthroughs in our understanding of the formation and evolution of galaxies, stars, and planetary systems, The authors wrote: 'The key outcome of six months of commissioning is this: JWST is fully capable of achieving the discoveries for which it was built. The commissioning report summarises six months of testing the JWST instruments, and was released yesterday along with the first official set of deep space photos. The success in this test opens up the possibility for the telescope to track near-Earth asteroids (NEAs), comets and other interstellar objects. 'These observations verified the expectation that guide star acquisition works successfully as long as Jupiter is at least 140" away from the FGS, consistent with pre-flight modeling.' The commissioning report explains: 'Observing a bright planet and its satellites and rings was expected to be challenging, due to scattered light that may affect the science instrument employed, but also the fine guidance sensor (FGS) must track guide stars near the bright planet. These images also demonstrate its ability to capture details like rings and moons around bright planets. Jupiter was the slowest target, moving at just 3.3 milliarcseconds per second, but all tests were successful. ![]() Other onboard instruments tested include the Near Infrared Imager and Slitless Spectrograph (NIRISS) and the Mid-InfraRed Instrument (MIRI), which detect and stabilise different wavelengths. NASA chose nine targets to test the telescope's ability to track fast-moving objects, which moved at speeds of up to 67 milliarcseconds per second. ![]() Jovian means 'Jupiter-like' and describes Jupiter, Saturn, Uranus and Neptune in our solar system. The report states that the pictures 'demonstrated that JWST can track moving targets even when there is scattered light from a bright Jovian planet'. The small, round, dark spots appearing in some frames are the shadows cast by the moons passing between Jupiter and the Sun, while the small, white flashes around the planet, are the moons themselves.The two images were taken by JWST's Near-Infrared Camera (NIRCam), and each use a different filter to highlight separate wavelengths of light. These pictures were taken every 10 hours over 28 days in 1979 each frame shows Jupiter at the same local time with the Great Red Spot appearing stationary within its cloud belt while clouds move right to left past it other cloud belts move left to right.

The small, round, dark spots appearing in some frames are the shadows cast by the moons passing between Jupiter and the Sun, while the small, white flashes around the planet, are the moons themselves. These pictures were taken from 01/06 to 02/03, 1979 and Voyager 1 flew from 58 million to 31 million kilometers from Jupiter during that time. One image was taken every Jupiter day (approximately 10 hours). ![]() ![]() English: Jupiter seen by Voyager 1 probe with blue filter.
