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