In 2004 a deeper image, known as the Hubble Ultra-Deep Field (HUDF), was constructed from a few months of light exposure. The HUDF image was at the time the most sensitive astronomical image ever made at visible wavelengths, and it remained so until the Hubble eXtreme Deep Field (XDF) was released in 2012.
NGC 2566 is a barred spiral galaxy in the constellation of Puppis.Its velocity with respect to the cosmic microwave background is 1898 ± 19 km/s, which corresponds to a Hubble distance of 91.3 ± 6.5 Mly (28.00 ± 1.98 Mpc). [1]
Webb's First Deep Field is the first full false-color image from the JWST, [12] and the highest-resolution infrared view of the universe yet captured. [11] The image reveals thousands of galaxies in a tiny sliver of the universe, with Webb's sharp near-infrared view bringing out faint structures in extremely distant galaxies, offering the most ...
The 18 images of HD 84406 are matched to their respective mirror segments, and the 18 segments are brought into approximate alignment centered on the star ("Segment Image Identification"). Each segment was then individually corrected of its major focusing errors, using a technique called phase retrieval , resulting in 18 separate good quality ...
Such of this phenomenon occurs, when a massive celestial body such as a galaxy cluster which creates sufficient curvature of spacetime for the path of light to be bent by the lens. [5] [6] This creates multiple images of the original galaxy which as seen, the background object appears as a distorted arc or a ring. [5]
Some of the latter may be visible in gravitational lensing in looking at deepest images such as the Hubble Ultra-Deep Field (i.e., their brief existence before their turning into supernovae). As with HD 122563, CS22892-0052, and CD−38 245, HD 140283 has an excess of oxygen and the alpha elements relative to iron. [1]
A mid-infrared image of NGC 4725 taken by the Spitzer Space Telescope (SST) NGC 4725 is a suspected type 2 Seyfert galaxy with a supermassive black hole at the core. [ 13 ] The morphological classification of this galaxy is SAB(r)ab pec, [ 5 ] indicating a peculiar, weakly-barred spiral galaxy (SAB) with a complete ring surrounding the bar (r ...
NGC 676 is a lenticular [6] Seyfert 2 galaxy [4] in the constellation Pisces. [2] Its velocity with respect to the cosmic microwave background is 1217 ± 20 km/s, which corresponds to a Hubble distance of 58.6 ± 4.2 Mly (17.96 ± 1.29 Mpc). [2]
