Explanation:
A bright spiral galaxy of the northern sky, Messier 63 is about 25 million
light-years distant in the loyal constellation Canes Venatici. Also cataloged
as NGC 5055, the majestic island universe is nearly 100,000 light-years across.
That's about the size of our own Milky Way Galaxy. Known by the popular
moniker, The Sunflower Galaxy, M63 sports a bright yellowish core in this
sharp, colorful galaxy portrait. 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, M63 has faint, extended features that could be
the result of gravitational interactions with nearby galaxies. In fact, M63
shines across the electromagnetic spectrum and is thought to have undergone
bursts of intense star formation.
