Astronomers utilizing the NASA/ESA Hubble Space Telescope have actually produced a lovely brand-new picture of the intermediate spiral nebula NGC 5042.

NGC 5042 lies around 48 million light-years far from Earth in the constellation of Hydra.
Otherwise referred to as ESO 508-31, LEDA 46126 or IRAS 13127-2343, the galaxy has a size of 80,000 light-years.
NGC 5042 was found by the British astronomer John Herschel on March 25, 1836.
“NGC 5042 perfectly fills the frame of this Hubble image, with a single Milky Way star marked by cross-shaped diffraction spikes trying to mix in with the brilliant stars along the galaxy’s edge,” the Hubble astronomers stated in a declaration.
The center of NGC 5042 is loaded with ancient stars, and the galaxy’s spiral arms are embellished with spots of young blue stars.
“The lengthened yellow-orange things that are spread around the image are background galaxies much more far-off than NGC 5042,” the astronomers stated.
“Perhaps NGC 5042’s most striking function is its collection of dazzling pink gas clouds that are studded throughout its spiral arms.”
“These fancy clouds are called H II areas, and they get their unique color from hydrogen atoms that have actually been ionized by ultraviolet light.”
“If you look carefully at this image, you’ll see that much of these reddish clouds are connected with clumps of blue stars, typically appearing to form a shell around the stars.”
“H II areas emerge in extensive clouds of hydrogen gas, and just hot and huge stars produce sufficient high-energy light to develop an H II area.”
“Because the stars efficient in developing H II areas just live for a couple of million years– simply a blink of an eye in stellar terms– this image represents a short lived picture of life in this galaxy.”
The brand-new picture of NGC 5042 is comprised of observations from Hubble’s Wide Field Camera 3 (WFC3) in the ultraviolet, near-infrared, and optical parts of the spectrum.
6 filters were utilized to sample different wavelengths. The color arises from designating various shades to each monochromatic image related to a private filter.
“Hubble observed NGC 5042 in 6 wavelength bands from the ultraviolet to the infrared to develop this multicoloured picture,” the scientists stated.
