Barnard 175 -- Kitt Peak National Observatory

IC 1805: The Heart Distance: 7,500 Light Years Located in the Perseus arm of the Galaxy in the constellation Cassiopeia. This is an emission nebula showing glowing gas and darker dust lanes. The nebula is formed by plasma of ionized hydrogen and free electrons. The nebula’s intense red output and its configuration are driven by the radiation emanating from a small group of stars near the nebula’s center.

The Witch Head Nebula (IC 2118) is a reflection nebula believed to be an ancient supernova remnant. It lies in the Eridanus constellation, about 900 light-years from earth. It is lit up by nearby blue supergiant star Rigel, the brightest star in Orion and the sixth brightest star in the sky.

NGC7129: star-forming region & reflection nebula in Cepheus; it is about 3000 ly away; stars in this nebula are very young, about 1 Ma old. The red blobs above & below the nebula are Herbig Haro objects, the result of jets of gas streaming away from young stars in the nebula

Mark Of a Dying Star: Six hundred and fifty light-years away in the constellation Aquarius, a dead star about the size of Earth, is refusing to fade away peacefully. NASA's Hubble and Spitzer Space Telescopes have captured the complex structure of the Helix nebula. -NASA/JPL-Caltech/ESA

NGC 6559 is a star-forming region (in Simeis 188) about 5000 ly away in Sagittarius, showing both emission- red & reflection- bluish
