Most galaxies in the cosmos conform to a regular pattern but there are some rebels that are sure-footed about rocking a different look . stargazer have just discovered something very interesting about one of them . PGC 1000714 is a rare galax that has an elliptical core and is surrounded by two rings .
This galaxy belongs to the exceedingly rare class known asHoag - type galaxiesand is located 359 million abstemious - age from Earth . The red core of PGC 1000714 is 5.5 billion years honest-to-goodness , made by older wizard , while the outer gang is full of young stars and is only about 130 million years old .
By ground the long time divergence between the ring and the core , the research worker detect something unexpected : a diffuse red 2d inner ring closely surrounding the center of the galaxy . A detailed investigation of the object has been put out by theMonthly Notices of the Royal Astronomical Society .

" The unlike colors of the inner and KO’d closed chain suggest that this galaxy has experienced two dissimilar geological formation menstruation , " lead author Burcin Mutlu - Pakdil , from the University of Minnesota Duluth , enounce in astatement . " From these initial individual snapshots in time , it ’s impossible to know how the ring of this special galax were formed . "
The researchers mistrust the outer ring take form from the gas of a small-scale nearby wandflower that was slowly shredded apart . The blood line of the privileged disk instead remains a fleck more mysterious , and the astrophysicist have stated that high resolution watching are necessary to understand what precisely they are learn here .
" Whenever we find a alone or unusual objective to analyze , it challenge our current hypothesis and assumptions about how the Universe works . It usually tell us that we still have a lot to learn , " added co - author Patrick Treuthardt , from the North Carolina Museum of Natural Science .
Hoag - type galaxy are less than 0.1 per centum of all the observe galaxy and the curiosity of cause a double ring makes this a in truth rare discovery .
