Jupiter has lost one of its bands. Of the two bands of brown color existing, one above the other below the equator, it is only one left, one above the equator. The discovery was made by an Australian amateur astronomer on May 9 that he then published on the internet photos.
Jupiter was photographed in 2009 before they get too close to the Sun so it can not be well observed from the Earth, and the band of brown that was below the equator was still clearly visible. In April of this year Jupiter is back to being visible from Earth and has been noted the absence of the band of brown below the equator.
According to NASA astronomers the cause of the disappearance of the band could be due to overlap of some processes of the various layers of clouds.
