Hubble Snaps Beautiful Image of NGC 4907 | Astronomy – Sci-News.com


Astronomers using the NASA/ESA Hubble Space Telescope have captured a vivid image of the face-on barred spiral galaxy NGC 4907.
This Hubble image shows NGC 4907, a barred spiral galaxy located 284 million light-years away in the constellation of Coma Berenices. The image is a composite of separate exposures acquired by Hubbles Wide Field Camera 3 (WFC3). Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / M. Gregg.
NGC 4907 resides some 284 million light-years away in the northern constellation of Coma Berenices.
NGC 4907 is part of the Coma Cluster, a group of over 1,000 galaxies, some of which can be seen around this galaxy in this image, Hubble astronomers said.
This massive cluster of galaxies lies within the constellation of Coma Berenices, which is named for the locks of Queen Berenice II of Egypt: the only constellation named after a historical person.
Also referred to as LEDA 44819, ECO 3847, AGC 221418, GMP 2441 and GP 215 in various astronomical catalogues, NGC 4907 was discovered by the German astronomer Heinrich dArrest on May 5, 1864.
The galaxy is also classified as a LINER (low-ionization nuclear emission-line region) galaxy, a class of active galaxies characterized by the presence of strong, nuclear, low-ionization emission lines.
This new image from Hubble displays its beautiful spiral arms, wound loosely around its central bright bar of stars, the researchers said.
Shining brightly below the galaxy is a star that is actually within our own Milky Way Galaxy.
This star appears much brighter than the many millions of stars in NGC 4907 as it is 100,000 times closer, residing only 2,500 light-years away.
