Discovered in 1826 by James Dunlop, NGC300 is a grand spiral galaxy residing in the constellation Sculptor.
The galaxy’s diffused spiral arms are abundant with young blue stars and red-pink gaseous nebulae being heated by the stars. The nebulae form different shapes as a result of shock waves from stellar explosions.
NGC300 is one of the brightest members of the Sculptor Group of galaxies, a grouping which is closest to the Local group that includes our Milky Way galaxy. NGC300 is located approximately six million light-years away.
Arp 87 is a stunning pair of interacting galaxies. Stars, gas, and dust flow from the large spiral galaxy, NGC 3808, forming an enveloping arm around its companion. The shapes of both galaxies have been distorted by their gravitational interaction. Arp 87 is located in the constellation of Leo, the Lion, approximately 300 million light-years away from Earth. Arp 87 appears in Arp’s Atlas of Peculiar Galaxies. As also seen in similar interacting galaxies, the corkscrew shape of the tidal material suggests that some stars and gas drawn from the larger galaxy have been caught in the gravitational pull of the smaller one.
