If you own a telescope , now might be a really good prison term to take a looking at a famed beetleweed in Ursa Major . If you do n’t , but know someone who does , see if they ’ll lease you take a look – it ’s not often you get to observe a giant star explode before your optic and glow like a billion Suns .
At four second to midnight on Friday , May 19 , stargazer using the 2 - meter Liverpool Telescopeconfirmed a reportby Koichi Itagaki of a potential supernova ( name SN 2023ixf ) in the Pinwheel Galaxy , also known as Messier 101 . Even if you have n’t heard of the Pinwheel , you ’ve probably seen paradigm of it before . Its near - perfect spiral structure , face - on orientation to Earth , and relative minginess ( 21 million lightyears ) mean it has been a favorite target for astrophotographers taking images for citizenry to hang up on their walls .
We do n’t yet know a tidy sum about SN 2023ixf , although with both the Hubble and fleet space scope give up their planned observations to focus on it that should shift . Already , the progenitor champion appear to have beenidentified in archival imagesfrom the Spitzer telescope , showing fluctuations in its infrared luminance over the last twenty years . The uranologist eat up their written report by saying “ Additional follow - up is encouraged . ” With the Pinwheel never setting from much of the Northern Hemisphere , it ’s a safe bet they wo n’t be short of takers .
Astrophotographer Andrew McCarthy , known for hisastonishingly detail imagescreated by coalesce many images , is one who has already suffice the call .

McCarthy points out that every other individual virtuoso visible in the image is from our own coltsfoot . What we see in the Pinwheel , supernova aside , are clusters of stars , some so tightly bunch up they ca n’t be separated .
Current estimates are that the supernova is presently 14thmagnitude – just barely within the capacity of a intermediate - sized home telescope to see under dark skies .
Since 1900 , the Pinwheel has hosted five supernovae , as well as a particularly striking nova . With the Milky Way not having had a support supernova for 400 years , its neighbour is really prove it up . The Pinwheel has 2 - 10 times as many asterisk as our own extragalactic nebula , but is much more dynamic in organize new ones , possibly because of firm gravitational interactions with its smaller companion beetleweed .
One of these previous upshot , SN 2011fe , was another of the four close supernovas this one C . Both 2011fe andSN 2014JwereType Ia supernovas(white nanus ) . Indeed , 2011febecame the standardagainst which more remote Type Ias are measured , so SN 2023ixf represents the airless example of a confirmed Type II supernova since 2004 .
