The NASA/ESA Hubble Space Telescope has captured an incredible new photograph of NGC 1385, a barred spiral galaxy in the Fornax constellation.
This Hubble image shows NGC 1385, a barred spiral galaxy about 68 million light-years away in the constellation Fornax. The color image is composed of observations made by Hubble’s Wide Field Camera 3 (WFC3) in the ultraviolet, near-infrared and optical parts of the spectrum. Six filters were used to sample various wavelengths. Color results from assigning different tones to each monochrome image associated with an individual filter. Image credit: NASA/ESA/Hubble/R.

NGC 1385 It is located approximately 68 million light years away, in the constellation Fornax.
This galaxy was discovered on November 17, 1784 by the British astronomer of German origin William Herschel.
Also known as AGC 22776, ESO 482-16, LEDA 13368 and IRAS 03353-2439, it has a diameter of about 70,000 light years.
NGC 1385 is a member of the NGC 1385 group, a gathering of more than 30 galaxies.
The galaxy also belongs to the Eridanus Cluster, a larger group that includes about 200 galaxies.
“NGC 1385 was the subject of another Hubble imagebut the two images are strikingly different, Hubble astronomers said.
“The new image has a lot more pinkish red and shadow tones, whereas the previous image was dominated by cool blues.”
“This chromatic variation is not only a creative choice, but also a technical one, made to represent the different number and type of filters used to collect the data that were used to create the respective images.”
“It’s understandable to be a little confused about how the same galaxy, imaged twice by the same telescope, could be represented so differently in two different images,” they said.
“The reason is that, like all powerful telescopes used by professional astronomers for scientific research, Hubble is equipped with a variety of filters.”
“These highly specialized components bear little similarity to the filters used in social media: those software-driven filters are added after the image has been taken and cause image information to be lost as certain colors are exaggerated. or reduced to achieve an aesthetic effect.
“In contrast, telescope filters are pieces of physical hardware that only allow very specific wavelengths of light to enter the telescope as data is collected.”
“This causes light to be lost, but it means astronomers can explore extremely specific parts of the electromagnetic spectrum.”
“This is very useful for several reasons; “For example, physical processes within certain elements emit light at very specific wavelengths and filters can be optimized for these wavelengths.”
