The Heart Nebula is an emission nebula, 7,500 light-years (2,300 pc) away from Earth and located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. In 1958, it was identified as a radio source by Gart Westerhout and is therefore also referred to as Westerhout 4 . It displays glowing ionized hydrogen gas and darker dust lanes.

NGC 7331 is a large, unbarred spiral galaxy in the constellation Pegasus, located roughly 39-40 million light-years away and often cited as one of the closest visual analogs to our own Milky Way in overall size and structure. Discovered by William Herschel in 1784, it is inclined steeply to our line of sight, showing an elongated disk, a prominent central bulge, and a dust lane along one edge; unusually, its bulge is known to rotate in the opposite direction to its outer disk.

NGC 6946, sometimes referred to as the Fireworks Galaxy, is a grand design, face-on intermediate spiral galaxy with a small bright nucleus, whose location in the sky straddles the boundary between the northern constellations of Cepheus and Cygnus. Its distance from Earth is about 25.2 million light-years or 7.72 megaparsecs, similar to the distance of M101 in the constellation Ursa Major. Both were once considered to be part of the Local Group, but are now known to be among the dozen bright spiral galaxies near the Milky Way but beyond the confines of the Local Group. NGC 6946 lies within the Virgo Supercluster.
