The “migratory planet” .. questions of life without the sun


However, an Egyptian astronomer called for not to rush the results, as measurements of the paths of planets outside our solar system may differ greatly from those of planets outside the group.

The importance of the arduous studies being made by scientists about the planets and components of the astronomicals stems outside Sun Group To the hope of finding life there, water and minerals that can be transported to a land threatened by the depletion of its resources.

According to the scientific journal, this came after determining the atmosphere’s chemical footprint of the planet, and it showed that it had moved to its current location 7 million kilometers from its birthplace or first formation, or the equivalent of 1/20 by calculating the distance from Earth to the sun.

The results of the research conducted by an international team of astronomers led by the University of “Warwick” in Britain represent the first time that about 6 particles in the atmosphere of a planet outside the solar system have been measured to determine its composition, and it is also the first time that astronomers have used these six particles to determine the position. In which these hot extrasolar planets form these giant planets.

According to the study’s lead researcher from the Department of Physics at the University of “Warwick” Dr. Sidharth Gandhi: “We used these six chemical types for the first time to narrow down the place where they were originally formed in the primary planetary disk.”

For this research, the Galileo Telescope in La Palma, Spain, was used to obtain high-resolution spectra from Atmosphere For the exoplanet HD 209458b as it passes in front of its host star on four separate occasions, and it is found that the light from the star as it passes through the planet’s atmosphere changes, and by analyzing the differences in the resulting spectrum, the chemicals present and their quantity can be determined.

Regarding these substances, Gandhi says that hydrogen cyanide, methane, ammonia, acetylene, and hydrogen cyanide were discovered for the first time.Carbon Monoxide And low amounts of water vapor in HD 209458b’s atmosphere, twice what carbon would have been expected.

According to the astronomer’s assessment, “the main chemicals are carbon-bearing species.”NitrogenAnd if these species are at the level that we discovered, then this indicates the presence of an atmosphere rich in carbon compared to oxygen. “

The indication of this is that a carbon-rich gas accumulated preferentially during the formation, which only happens if it rotates far away from its star in the place where it was formed from the beginning, i.e. the place of birth, and at a similar distance to Jupiter or Saturn in the solar system.

Searching for new water for the Earth

Commenting on these results, the head of the Egyptian National Institute for Astronomical and Geophysical Research, Gad Al-Qadi, says, “The primary goal behind this research and conclusion, which I monitored Ground TelescopesSince mankind has not yet launched the mission of space outside the solar system, which is to search for the possibility of life on other planets, and to search for alternative natural resources on Earth, such as water and minerals, that threaten humanity to run out.

The judge pointed out, in statements to “Sky News Arabia” that: “The conclusion that a planet outside the solar system may have migrated far from its original place of birth may be a key to discoveries further away from the secrets of the Milky Way, which have been revealed very little. very”.

However, he cautioned that “the conclusion may be inaccurate”; Because “there may be a difference between the paths of these planets from those paths that we know and calculate for our solar system.” Therefore, “proving or denying that still needs more research and studies.”
