Astronomers Discover , Unusual Galaxy , That Should Not Exist.<br />'Newsweek' reports that NASA's <br />James Webb Telescope has discovered <br />a new galaxy that shouldn't exist. .<br />The dwarf galaxy, referred to as PEARLSDG, <br />was spotted in an area of space where <br />astronomers were not expecting to find anything.<br />A new paper in the 'Astrophysical Journal Letters' <br />details the strange properties of PEARLSDG, <br />chiefly how it appears to not be forming new stars.<br />Normally, dwarf galaxies <br />orbit larger galaxies, which <br />influences their formation. .<br />Our Milky Way is orbited by <br />about 20 dwarf galaxies, like the Small <br />Magellanic Cloud and Triangulum II.<br />PEARLSDG appears to not be <br />interacting with any nearby galaxies, <br />while also not forming any new stars.<br />Scientists now believe PEARLSDG <br />is a rare isolated quiescent galaxy. .<br />These types of isolated quiescent <br />dwarf galaxies haven't really been seen <br />before except for relatively few cases, Tim Carleton, paper co-author and an assistant research <br />scientist at Arizona State University, via 'Newsweek'.<br />They are not really expected to <br />exist given our current understanding <br />of galaxy evolution, so the fact that we <br />see this object helps us improve our <br />theories for galaxy formation, Tim Carleton, paper co-author and an assistant research <br />scientist at Arizona State University, via 'Newsweek'.<br />Generally, dwarf galaxies that <br />are out there by themselves are <br />continuing to form new stars, Tim Carleton, paper co-author and an assistant research <br />scientist at Arizona State University, via 'Newsweek'.<br />'Newsweek' reports that the findings suggest that <br />astronomers have much more to learn about dwarf <br />galaxies, including how they evolve over time.
