The NASA/ESA Hubble Space Telescope has actually supplied astronomers a comprehensive brand-new picture of the disallowed spiral nebula NGC 5668.
In this picture of the disallowed spiral nebula NGC 5668, Hubble was utilized to take a look at the environments of the Type II supernova occasion identified SN 2004G, looking for to study the type of stars that end their lives as this type of supernova. The color image is made up of near-infrared and optical observations from Hubble’s Advanced Camera for Surveys (ACS). 2 filters were utilized to sample different wavelengths. The color arises from designating various shades to each monochromatic image related to a specific filter. Image credit: NASA/ ESA/ Hubble/ C. Kilpatrick.
NGC 5668 depends on the constellation of Virgo, roughly 90 million light-years away.
Otherwise referred to as IRAS 14309 +0440, LEDA 52018 or UGC 9363, this galaxy was found on April 29, 1786 by the German-born British astronomer William Herschel.
NGC 5668 belongs to 2 groups of galaxies: the NGC 5638 group and NGC 5746 group.
“At very first blush, NGC 5668 does not look like an amazing galaxy,” the Hubble astronomers stated.
“It is around 90,000 light-years throughout, comparable in size and mass to our own Milky Way Galaxy, and its orientation almost face-on to us reveals open spiral arms made from cloudy, irregular spots.”
“One obvious distinction in between the Milky Way and NGC 5668 is that this galaxy is forming brand-new stars 60% faster.”
“This reality belies a galaxy with churning clouds and circulations of gas, severe weather condition that forms exceptional conditions for the development of brand-new stars.”
The astronomers determined about 2 primary motorists of star development in NGC 5668.
“Firstly, this top quality Hubble picture exposes a bar at the center,” they stated.
“It may look more like a small oval shape than a genuine bar, however it appears to have actually affected the galaxy’s star development rate, as main bars carry out in numerous spiral nebula.”
“Secondly, high-velocity clouds of hydrogen gas have actually been tracked moving vertically in between the disk of the galaxy and the round, faint halo which surrounds it.”
“These can be produced by the strong outstanding winds of hot, enormous stars, and they contribute gas to brand-new star-forming areas.”
“The boosted star development rate in NGC 5668 includes a matching abundance of supernova surges,” they stated.
“Three have actually been identified in the galaxy, in 1952, 1954 and 2004.”
