A research team from the NASA's Hubble Space Telescope has announced the discovery of the mystery of the sudden disappearance of a planet orbiting one of the stars of the Southern Whale constellation. The last observations of the star, during the past three years, have documented these observations.

The mouth of the whale
The results, which were issued by a study in the periodicals of the National Academy of Sciences (BNAAS), on April 20, came to say that this disappearance indicates that this planet, called "The mouth of the whale B", was not a planet at all. Rather, a cloud of gas, dust and snow formed by a severe impact occurred in this region tens of thousands of years ago.

According to the new study, the space surrounding the whale's mouth star (Fomalhaut) is not ideal as is the case with the sun, but rather contains loops of debris and dust scattered all around the star, which is likely to cause collisions of this nature between bodies similar to those in a belt Planets of the Solar System.

To reach these results, the research team used micro-computers at the University of Arizona, USA, to examine a large amount of data reported by the Hubble Telescope over several years, in an attempt to build a mathematical model that analyzes the movement of the "whale's mouth B" and explores changes in its nature.

This model came to show that before its disappearance, the size of the planet had slightly enlarged during its movement, indicating that it was a cloud of dust.

Observing date Observations
from the Hubble Telescope beginning in 2004 indicated a moving pattern between that debris suggesting the existence of a planet believed to be larger in mass than Jupiter, at a distance of about a star equal to two hundred times as much as the distance between Earth and the Sun.

These results were confirmed in 2008, and then the existence of the "mouth of the whale B" planet was announced, but the last observations of the Hubble telescope indicated its disappearance.

The mouth of the whale is about 25 light-years away from us, a huge star in which we can put four balls the size of the sun, and since the discovery of the gas and dust rings around it has been the focus of extensive research interest, because it is relatively close to Earth.

On autumn nights, you can see this star with your own eyes, as it is one of the brightest stars of the southern horizon of the night sky, just use the stars of the "forearm" and "the shoulder" of the constellation of the Great Persians and extend the line between them on its straightness to the south.
