Hubble Confirms more Dark Spots on Neptune

In the latest NASA’s space Hubble Space Telescope have detected the presence of a new dark vortex in the Neptune’s atmosphere. Similar features were recorded during the Voyager 2 flyby of Neptune in 1989, Hubble Space Telescope in 1994. Experts on the Hubble Space telescope suggest that the dark vortex of Neptune are high pressure systems and are accompanied with “Bright companion clouds”. Neptune is  the eight and second farthest known planet from the sun. The furthest being the new Ninth Planet in the solar system.


Neptune is the most dense among all the giants hovering around the sun. Galileo was the first person who plotted the position of Neptune. When Pluto was discovered it was taken as the farthest known planet. Later astronomers debated that Pluto should be considered a part of the Kuiper Belt. The Mass of Neptune is seventeen times that of the earth. It’s gravity is 11.15 m/s^2 and the radius of 24,764 kilometers.

Neptune spins on its axis very fast its equatorial clouds take only 18 hours to make one rotation. It has the most active climate system in the entire solar system. Large storms whirl through its upper atmosphere making it impossible to see the surface. It has fourteen moons one of the moon Triton is most frozen world  in our entire Solar System.

In another worst pictures from Space, the Neptune is seen as having a dark spot covered in bright clouds. We have very less information about the planet. In fact we know more about Pluto than Neptune. So this is being taken as one of the remarkable pictures of our outer solar system. Take a look!

Dark Vortex Neptune


Neptune’s dark vortices exhibit surprising diversity over the years. They tend to speed up and slow down on their own. The new data enables the Hubble team to create a higher quality map of vortex and its surroundings. Astronomers are hoping to better understand how dark vortices originate, and how are their oscillations controlled by atmosphere. Joshua Tollefson, recently awarded NASA Earth and Space Science started a fellowship in studying the Neptune’s atmosphere.

In the future astronomers are hoping to deeply understand the solar system and the phenomenons. That occurs on almost all the planets but from millions of miles away it is tough to understand the inner workings. Project Hubble has completed many such milestones where information given from the satellite have opened up our insight about the Gaseous giants.
