11. Southern Pinwheel
Messier 83 (also known as the Southern Pinwheel Galaxy) is an intermediate spiral galaxy approximately 15 million light-years away from home. It is one of the closest and brightest barred spiral galaxies in the sky, making it visible with binoculars.
12. Saturn Aurora
The magnetosphere of Saturn is the cavity created in the flow of the solar wind by the planet’s internally generated magnetic field. Discovered in 1979 by the Pioneer 11 spacecraft, Saturn’s magnetosphere is the second largest of any planet in the Solar System after Jupiter.
13. Cone Nebula
The cone nebula is located about 2,600 light-years away from Earth. The Cone Nebula forms part of the nebulosity surrounding the Christmas Tree Cluster.
14. Horse Head Nebula
The Horsehead Nebula (also known as Barnard 33 ) is a dark nebula in the constellation Orion. It is approximately 1500 light years from Earth. It is one of the most identifiable nebulae because of the shape of its swirling cloud of dark dust and gases, which is similar to that of a horse’s head.
15. Sombrero Galaxy
The Sombrero Galaxy is an unbarred spiral galaxy in the constellation Virgo. It has a bright nucleus, an unusually large central bulge. This galaxy’s most striking feature is the dust lane that crosses in front of the bulge of the galaxy. This dust lane is actually a symmetric ring that encloses the bulge of the galaxy.
16. Minkowski’s Butterfly
This bipolar nebula takes the peculiar form of twin lobes of material that emanate from a central star. Astronomers have dubbed this object as the Twin Jet Nebula because of the polar jets believed to cause the shape of the lobes. Its form also resembles the wings of a butterfly. The nebula was imaged by the Hubble Space Telescope in the 1990s.
17. Trifid Nebula
Trifid Nebula is a bright and colorful object, and is thus a perennial favorite of astronomers. It looks like a young eagle with spread wings sitting on a twig.
18. Eta Carinae
The Eta Carinae is visible as the bright area in the centre of the large bi-polar Homunculus Nebula. The stellar system contains multiple stars most of which are very bright, due the this their life is relatively short, and are expected to explode as a supernova or hypernova in the next million years.
19. Glowing Heart
The Heart Nebula lies some 7500 light years away from Earth. It is located in the Perseus arm of the Galaxy in the constellation Cassiopeia.This is an emission nebula showing glowing gas and darker dust lanes.This nebula is formed by plasma of ionized hydrogen.
20. Cat’s Eye Nebula
The Cat’s Eye Nebula , one of the first planetary nebulae discovered, also has one of the most complex forms known to this kind of nebula. Eleven rings, or shells, of gas make up the Cat’s Eye. In the center of the Cat’s Eye there is a bright and hot star, which around 1000 years ago lost its outer envelope producing the nebula.
