NGC2359 - Thor's Helmet459 viewsAn emission nebula in the constellation Canis Major. About 12,000 light-years distant and 30 light-years in size. Associated with the Wolf-Rayet star WR7.

M8, The Lagoon Nebula in Sagittarius457 viewsAn emission nebula lying 4000-6000 years from Earth. Also designated NGC 6523. An HII star-forming region. Contains the open cluster NGC 6530.

NGC 1499 - The California Nebula456 viewsAn emission nebula in the constellation Perseus, so called because it resembles the State of California in shape (though not in this image). About 1000 light-years from Earth.

NGC 7822 - Star-forming region in Cepheus455 viewsIncludes the emission nebula Sharpless 171 and the star cluster Berkeley 59. Around 3000 light-years from Earth.

NGC 7635 - The Bubble Nebula443 viewsEmission nebula in the constellation Cassiopeia. The bubble is created by the stellar wind from a hot, young star.

Sharpless2-1443 viewsCombination of a diffuse HII emission nebula and reflection nebula in the constellation of Scorpius with Pi Scorpii at its center.

Sharpless 11 - The War and Peace Nebula in Scorpius440 viewsHII region in Scorpius. Also known as Gum 66 and NGC 6357; ionised by the Pismis 24 and AH03 J1725−34.4 star clusters.

Westerhout 5, The Soul Nebula440 viewsEmission nebula in Cassiopeia, 7500 light-years away. Also known as Sharpless 2-199, LBN 667 and IC 1848, although the last is properly the designation of a star cluster within the nebula. Eastern neighbor of the Heart Nebula.

Tulip Nebula - Sh2-101439 viewsAn emission nebula about 6,000 light-years away in the constellation Cygnus. The shape vaguely resembles the outline of a tulip.

IC4592 - Blue Horsehead Nebula 436 viewsReflection nebula in the constellation Scorpius, lit by the giant septuple star Jabbah (Nu Scorpii). This photo shows only part of the nebula, so the horsehead shape is not evident here.

M42 - The Great Nebula in Orion435 viewsAnother take on the Great Orion Nebula, incorporating hydrogen-alpha data.

Sh2-311 - Emission nebula in Puppis430 viewsSharpless 311 (Sh2-311, NGC 2467, Gum 9, LBN 1065 + 1067) is a bright nebula located approximately 20,500 light-years away in the constellation Puppis.
