Explanation: A bright spiral galaxy of the northern sky, Messier 63 [5]  is
about 25 million light-years distant in the loyal constellation Canes Venatici
[6] . Also cataloged as NGC 5055, the majestic island universe [7] is nearly
100,000 light-years across. That's about the size of our own Milky Way [8]
Galaxy. Known by the popular moniker, The Sunflower Galaxy, M63 sports a
bright yellowish core in this sharp telescopic portrait [9] . Its sweeping
blue spiral arms are streaked with cosmic dust lanes and dotted with pink star
forming regions. A dominant member of a known galaxy group [10] , M63 has
faint, extended features that are likely star streams from tidally disrupted
[11]  satellite galaxies. M63 shines across [12] the electromagnetic spectrum
and is thought to have undergone [13] bursts of intense star formation.
