Images from telescopes with segmented mirrors also exhibit diffraction spikes due to diffraction from the mirrors' edges. As before, two spikes are perpendicular to each edge orientation, resulting in six spikes (plus two fainter ones due to the spider supporting the secondary mirror) in photographs taken by the James Webb Space Telescope .
NGC 1566, sometimes known as the Spanish Dancer, [7] [8] [9] is an intermediate spiral galaxy in the constellation Dorado, positioned about 3.5° to the south of the star Gamma Doradus. [10] It was discovered on May 28, 1826 by Scottish astronomer James Dunlop . [ 11 ]
James Webb Space Telescope Mirror alignment animations Segment image identification. 18 mirror segments are moved to determine which segment creates which segment image. After matching the mirror segments to their respective images, the mirrors are tilted to bring all the images near a common point for further analysis.
NASA’s Hubble Space Telescope recently captured a breathtaking image of the spiral galaxy NGC 2566. Astronomers use detailed Hubble images to study star clusters and active star-forming regions.
Astronomers used the James Webb Space Telescope to spot a Milky Way-like galaxy that formed soon after the big bang created the ... the newly discovered ceers-2112 is a barred spiral galaxy, and ...
The James Webb Space Telescope (JWST) is a space telescope designed to conduct infrared astronomy. As the largest telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant , or faint for the Hubble Space Telescope . [ 9 ]
JADES-GS-z14-0 is a high-redshift Lyman-Break galaxy in the constellation Fornax that was discovered in 2024 using NIRcam as part of the JWST Advanced Deep Extragalactic Survey (JADES) program. [ 1 ] [ 2 ] It has a redshift of 14.32, making it the most distant galaxy and astronomical object ever discovered.
NGC 7496 is a barred spiral galaxy located in the constellation Grus.It is located at a distance of about 60 million light-years from Earth, which, given its apparent dimensions, means that it is 75,000 light years across.
