❤️ Heart Nebula – The Stellar Heartbeat of Cassiopeia ❤️
Floating in the constellation Cassiopeia, the Heart Nebula (IC 1805, Sh2-190) lies about 7,500 light-years away. With an apparent magnitude of ~6.5, it’s bright enough to hint at its presence under dark skies, but its true glory emerges through long exposures.
This glowing H II region spans roughly 150′ × 150′ in the sky, illuminated by the central star cluster Melotte 15, whose massive O-type stars sculpt the surrounding gas and dust into the iconic heart shape.
