The Eastern Veil nebula (also known as Caldwell 33) is a cloud of heated and ionized gas and dust in the constellation of Cygnus and is located at around 1470 light-years from Earth. It is part of the Cygnus Loop which is a faint supernova remnant that exploded aproximately 7000 years ago. From the moment the source star exploded and until now, the Cygnus Loop supernova remnant expanded to a diameter of roughly 3° on the sky (that almost 6 full moons). The red hues in this […]

The Rho Ophiuchi cloud complex is a dark nebula of gas and dust that is located 1° south of the star ρ Ophiuchi of the constellation Ophiuchus. At an estimated distance of 131 ± 3 parsecs, it is one of the closest star-forming regions to the Solar System.

The Lagoon Nebula (catalogued as Messier 8 or M8, NGC 6523, Sharpless 25, RCW 146, and Gum 72) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region. The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region in the north-west of Sagittarius in a star-forming region in a nearby spiral arm’s Scutum-centered part. It was discovered by Charles Messier on June 5, 1764. Its name means […]

IC 405 (also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31) is an emission and reflection nebula[1] in the constellation Auriga, surrounding the bluish star AE Aurigae. It shines at magnitude +6.0. Its celestial coordinates are RA 05h 16.2m dec +34° 28′. It surrounds the irregular variable star AE Aurigae and is located near the emission nebula IC 410, the open clusters M38 and M36, and the K-class star Iota Aurigae. The nebula measures approximately 37.0′ x 19.0′, and lies about 1,500 light-years away […]

The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, close to Deneb (the tail of the swan and its brightest star). This nebula received its name because it ever so slightly resembles North America.

The Eagle Nebula (catalogued as Messier 16 or M16, and as NGC 6611, and also known as the Star Queen Nebula and The Spire) is a young open cluster of stars in the constellation Serpens, discovered by Jean-Philippe de Cheseaux in 1745–46. Both the “Eagle” and the “Star Queen” refer to visual impressions of the dark silhouette near the center of the nebula, an area made famous as the “Pillars of Creation” imaged by the Hubble Space Telescope. The nebula contains several active star-forming gas and dust […]
