It has been a groundbreaking year for astronomy with Wednesday marking the one-year anniversary of the first color images from NASA's James Webb Space Telescope (JWST). During this time, the ...
Before Webb, images like these only came from the Hubble Space Telescope, which rocketed into Earth's orbit in 1990. But the JWST pictures reveal the rewards of the 25 years and $10 billion NASA ...
A day after President Biden revealed the first image from the $10 billion James Webb Space Telescope, NASA released several more stunning images.
Webb's First Deep Field was taken by the telescope's Near-Infrared Camera (NIRCam) and is a composite produced from images at different wavelengths, totalling 12.5 hours of exposure time. [3] [4] SMACS 0723 is a galaxy cluster visible from Earth's Southern Hemisphere, [5] and has often been examined by Hubble and other telescopes in search of ...
Called the Cosmic Cliffs, Webb’s seemingly three-dimensional picture looks like craggy mountains on a moonlit evening. In reality, it is the edge of the giant, gaseous cavity within NGC 3324, and the tallest “peaks” in this image are about 7 light-years high.
Webb's optical design is a three-mirror anastigmat, [41] which makes use of curved secondary and tertiary mirrors to deliver images that are free from optical aberrations over a wide field. The secondary mirror is 0.74 m (2.4 ft) in diameter.
James Webb Space Telescope pics. The Whirlpool Galaxy lies about 27 million light-years away and contains hundreds of billions of stars. The stars are spread out into a pinwheel shape clustered ...
This deep field, taken by Webb’s Near-Infrared Camera (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours – achieving depths at infrared wavelengths beyond the Hubble Space Telescope’s deepest fields, which took weeks.
