M101 - Spiral Galaxy with Type IIL Supernova 2023ixf

M101 with SN 2023ixf (Ursa Major) SN 2023ixf (Type: IIL) discovered 2023-05-19.727 UT by Koichi Itagaki Alias: ZTF23aaklqou, AT2023iyi, AT2023jgd, AT2023jfz, PSN J14033858+5418421, PS23dij Discoverer Mag 14.9 (Clear filter)  ( Rochester Supernova site | TNS 2023ixf ) SN 2023ixf (Type: IIL) discovered 2023-05-19.727 UT by Koichi Itagaki at Mag 14.9 is located near M101's prominant star-forming region NGC 5461.  The supernova resulted from a exploding red supergiant and lies just 21 million light years away.  It's the closest core-collapse supernova to us since SN 1993J which lit up M81 (some 12 million ly away) in Spring 1993. The SN is designated of type II-L (L for 'linear') , which is characterised by a rapid rise to maximum brightness  followed by a slow and gradual decrease, that is thought to be brought about by ejection of the dead stars' outer hydrogen shell.

Segue 1 - Faint Dwarf Galaxy - 0.075 mly

Segue 1 (Leo) Milky Way Dwarf Galaxy Satellite Segue 1 is a dwarf spheroidal galaxy or globular cluster situated in the Leo constellation and discovered in 2006 by Sloan Digital Sky Survey. It is located at a distance of about 75,000 light years Segue 1 is one of the smallest and faintest satellites of the Milky Way. Its integrated luminosity is about 300 times that of the Sun which is much smaller than the luminosity of a typical globular cluster. Observations however indicate its mass is about 600,000 solar masses, which suggest that it is dominated by dark matter. In the image below the approximate area of Segue 1 dwarf galaxy  is indicated by large white circle. By comparison with reference image (Keck/Deimos image) the visible stars that are understood to lie in Segue 1 are indicated by green circles  [ Local Group Galaxies ] Note: a longer exposure is required to detect more stars lying in the dwarf galaxy
