Astronomers using the NASA/ESA Hubble Space Telescope took an incredible new photo of the Spiral Galaxy NGC 4941.
This Hubble image shows NGC 4941, a spiral galaxy in Virgo’s constellation, about 67 million light years away. The color image consists of near-infrared, optical and ultraviolet observations from Hubble’s Wide Field Camera 3 (WFC3). Six filters were used to sample different wavelengths. Colors are attributed to assigning different hue to each monochromatic image associated with an individual filter. Image credits: NASA/ESA/Hubble/D. Thilker.
NGC 4941 It is approximately 67 million light years away from Earth, the Virgo constellation.
Also known as AGC 530009, IRAS 13016-0516, Leda 45165, or UGCA 321. 60,000 light years Crossing.
It was discovered on April 24, 1784 by German and British astronomer William Herschel.
NGC 4941 is a member of two galaxy groups, the NGC 4941 group and the NGC 4697 group.
“Because this galaxy is nearby, in cosmic terms, Hubble’s sharp instruments can choose exquisite details such as individual star clusters and filament clouds of gas and dust,” said the Hubble astronomer.
“The Hubble data used to construct this image was collected as part of an observation program that investigates star formation and stellar feedback cycles in nearby galaxies.”
“When stars form in densely cold gas clusters, they start to affect their surroundings.”
“The stars heat and stir the gas clouds created by exploding as supernoves for the wind, starlight, and ultimately the large stars.”
“These processes collectively are called stellar feedback and affect the rate at which galaxies can form new stars.”
“After all, stars aren’t the only entities that provide feedback in NGC 4941,” they added.
“It’s in the heart of this galaxy Active galactic nuclei (AGN) – Look at Gas.
“When a black hole accumulates gas from the surroundings, it swirls into an overheated disk that glows brightly at wavelengths throughout the electromagnetic spectrum.”
“It resembles a star, but on a much larger scale – the active galactic nucleus shapes its surroundings through wind, radiation and powerful jets, changing not only the formation of stars but also the evolution of the entire galaxy.”
