The deepest, coldest ice ever measured in the universe had just undergone an extensive study by the flying observatory. While NIRISS was tracking the well-known white dwarf star WD1657+343, NIRCam took this galaxy-filled image. Astronomers will be able to better comprehend the evolution of galaxies by comparing these systems to galaxies in the nearby universe,” according to a statement from NASA.Īs part of the commissioning effort, the picture was taken by Webb’s near-infrared camera (NIRCam).

In the first year, about 7% of scientific observations will be devoted to the Solar System.Įarlier, an asteroid the size of two Kyiv TV towers flew past the Earth.“Due to the light’s redshift toward infrared wavelengths from these far-off galaxies, Webb’s superb infrared vision allows the telescope to look back in time. James Webb is expected to be commissioned in June. Other planned scientific goals in the Solar System include Saturn’s rings, the atmosphere of its moon Titan, observations of several icy objects in the Kuiper Belt and sporadic plumes emanating from the icy moon Europa. Observing the asteroid will help science to better consider the planets Uranus and Neptune, which were captured by only one NASA Voyager-2 spacecraft. Because to track asteroids, the telescope needs to switch between a colder and a hotter position, which can affect the fine alignment of mirrors and instruments. The public also can follow Webb’s progress online via a Where is Webb interactive tracker. Plans for the first year of observations by James WebbĪccording to NASA, James Webb faces several additional challenges when tracking moving targets. So a list of 40 names was compiled, among which we stopped at Tenzing 6841. The team specifically chose the asteroid in such a way that its name was associated with success, which was not achieved easily. STAR TRACKERS: use guide stars for coarse pointing of the telescope.
Coincidentally, the observations of James Webb were carried out just a few days before the 69th anniversary of the conquest of the peak on May 29, 1953.
This is an object from the main belt, named after Tenzing Norgay, a Tibetan mountaineer and one of the first two famous people who conquered Mount Everest together with Edmund Hillary. The asteroid chosen for observation was Tenzing 6841. 25, and completion of two mid-course correction maneuvers, the Webb team has analyzed its initial trajectory and determined the observatory should have enough propellant to allow support of science operations in orbit for significantly more than a 10-year science lifetime. Successful tracking of a nearby object shows that JWST can monitor both objects of the Solar System, and distant galaxies, stars and other distant objects that it will observe during its at least 20-year service life. After a successful launch of NASA’s James Webb Space Telescope Dec. Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. NASA’s James Webb Space Observatory (JWST) of the new generation observed a moving asteroid for the first time on the eve of the start of the commissioning period. brings you the latest images, videos and news from America's space agency.
