The US Aeronautics and Space Administration (NASA) announced the total number of “confirmed” planets that it has discovered outside our solar system so far.
She added that she had added 65 planets outside the solar system to the total confirmed planets discovered in the universe, bringing the number to 5005 planets. other.”
The nature of these planets varies between rocky like Earth, and the gas giant that is several times larger than Jupiter, and those orbiting two stars at the same time, and the planets that orbit around the remains of dead stars.
Commenting on this scientific discovery, Jesse Christiansen, head of the scientific archives department at the NASA Exoplanet Science Institute at the California Institute of Technology, Jesse Christiansen, said: “It is not just a number. Each of these planets represents a new world, a completely new planet. I’m excited about each one of them because we don’t know anything about them.”
“We are ushering in an era of discovery that will go beyond adding new planets to the list,” said Alexander Walshzan, University of Pennsylvania planetary professor and NASA project participant. The Transiting Exoplanet Survey Satellite TESS, launched in 2018, continues to make discoveries of more new exoplanets.”
“Powerful next-generation telescopes and their highly sensitive instruments, starting with the recently launched James Webb Space Telescope, are expected to pick up light from the atmospheres of exoplanets and read their gases to identify signs of conditions suitable for life formation,” Welchzan added.
“It is possible that we will find some kind of life somewhere,” he explained. Most likely of a primitive type. The close relationship between the chemistry of life on Earth and the chemistry found throughout the universe, as well as the discovery of organic molecules, suggests that the discovery of life itself is only a matter of time.”
