One giant black spot of Neptune that has been observed on the planet’s surface in 2015 is now fading away, according to the images taken by the Hubble Space Telescope.

The dark storms of Neptune have been first discovered by the end of the ’80s by the Voyager 2 space probe. Since then the Hubble has discovered two other similar storms in the middle of the ’90s but those have disappeared, eventually.

One of the Neptun’s giant storms is diminishing

The latest black spot on the Neptune’s surface was discovered in 2015 and as the Great Red Spot of Jupiter is shrinking, so does the Neptun’s black storm.

Like the Great Red Spot of Jupiter, the storm has an anticyclonic direction and absorbs all the matter from the frozen center of the planet. Just recently, it has begun to shrink.

These features give astronomers a unique opportunity to study deep winds that cannot be measured directly.

The giant black storm of Neptune is apparently made of hydrogen sulfide.

Observing the death of a giant storm means a lot for scientists

Unlike the Great Red Spot of Jupiter, which has been around for 200 years, the dark spot on Neptune is only a few years old, this being the first time when a Neptune’s storm can be studied while it’s fading away.

According to Michael H. Wong, an astronomer at the University of California, no other probe can now observe these storms on Neptune better than the Hubble.

However, now, only the Hubble telescope can provide the necessary information for the scientists to understand how rare or how common are these meteorological events on Neptune.

Astronomers were expecting a spectacular clouds activity when one of the giant black spots of Neptune is fading away. Unluckily for them, the Neptune’s latest found black storm will die slowly and quietly.
