NASA's 'Birds of a Feather' is empty yet mesmerizing; NASA Hubble shares picture

mysteries of vast universe and celestial objects have never failed to intrigue humans. more we see, more we find out that we are just a speck of dust as world is ermously huge. NASA and several research ncies have been researching and trying to find out answers to questions about formation of world we live in today. Recently NASA Hubble revealed a beautiful picture of "Birds of a Fear" as scientists deted it to be.

As we can see beautiful picture shared by ESA/ NASA Hubble Telescope, spiral pattern shown by galaxy is remarkably striking because of its delicate, feary nature. Due to its fear-like spiral arms, galaxy is deted as 'Birds of a Fear' by NASA scientist. However, name of galaxy is NGC 2775 and se "flocculent" round arms symbolise that re has been star formation in recent history galaxy.

This observation has revealed that re is virtually star formation in central part of galaxy, NGC 2775 and so it is w named as an empty galactic bulge where all gas was converted into stars long ago. This galaxy is located 67 million light-years away in constellation of Cancer and it is classified as a flocculent spiral galaxy.

name "Birds of a Fear" comes as we observe this "relatively empty galactic bulge" closely. NGC 2775 is filled with millions of bright, young, blue stars that shine in fear-like spiral arms, interlaced with dark lanes of dust. scientist believes that complexes of se hot, blue stars will trigger star formation in nearby gas clouds. pattern of fear-like spiral arms appears due to shearing of gas clouds as galaxy rotates.
