“NGC 891 is a galaxy about 30 million light-years away from the Andromeda galaxy, discovered by William Herschel on October 6, 1784. This galaxy is a member of the NGC 1023 galaxy in the local supercluster.” Do you think We are alone in the Universe?
This object is the closest of all bright planetary nebulae to Earth. At present the distance measured by GAIA is 655 ± 13 light years.

During the mainstream phase of stellar evolution, the outer layers expand and the core shrinks as the stars become red giants. Externally expanding outer layers are separated from the star by various actions. This part of the planet is called the Planetary Nebula. Named the Planetary Nebula, it has nothing to do with the Planet….
NGC 7000 is an emission nebula in the constellation Swan.The nebula was discovered on October 24, 1786 by the German-British astronomer William Herschel.Distance from Earth: 2,202 light-yearsBrightness: 4Radius: 50 light yearsCoordinates: RC 20h 59m 17s | Dec +44° 31′ 44″Absolute brightness The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in…
IC 405 (also known as the Flaming Star Nebula, SH 2-229 or Caldwell 31) is an emission/reflection nebula in the constellation of Voerman, The nebula “shines” at a magnitude of 6. It surrounds the star AE Aurigae and is close to nebula IC 410, the open star clusters Messier 38 and Messier 36, and the…
The Elephant Trunk Nebula is a portion of interstellar gas and dust in the IC1396 ionized gas region, located in the constellation Cepheus, about 2,400 light-years from Earth.The Elephant Trunk Nebula is now considered to be the site of star formation, which contains very young (less than 100,000 years old) stars found in infrared images…
But a deeper exposure and a much more careful processing will reveal that these galaxies, far from being visualized against a nearly dark, empty background, they are surrounded by huge clouds of dust…The truth is that the galaxies are not surrounded by this dust – the dust is much closer to us than the galaxies…
