An international team of scientists and researchers confirmed the existence of an extrasolar planet that is likely to live. The planet was identified about two years ago by Dr. Michael Cretegner, a professor at Oxford University. This finding can greatly contribute to future studies on extrasolar planets. The planets that rotate by a star are called extensive planets.
According to RCO News Agency quoting Oxford University, The new planet, named after the HD 4 D, is six times the mass of the earth and rotates around a star similar to the sun, which is 5 light -years away. The planet’s orbit is located in the habitable area of the poem, which means it is at the right distance from its star, which keeps the liquid water on its surface.
Dr. Creteigner identified the first signal of the extrasolar planet in year 6 when he was analyzing at the La Sila Observatory in Chile. Dr. Creteigner saw distinct periodic changes in the spectrum of light emitted by the host star, which could have been due to the gravitational pull of a adjacent planet. However, due to the weakness of the signal, it was not determined whether it was by a planet or due to a instrumental error.
To confirm the signal, an international team made very accurate measurements by the HARPS spectrum. This spectrar and its more advanced example, ESPresso, are the most advanced tools in the world to measure small changes in light spectra.
Although the planet is in the habitable area of the poem, it is still too early to say that it can host life. Unlike most planets, the HD ۱۹۴۹ D -circuit is not circular; Rather, it is elliptical. The planet’s distance from its star changes significantly, which causes the planet to move from the outer edge of the habitable area to the inner edge throughout the year.
In any case, the HD 4 D provides a valuable trial for future space projects designed to identify the signs of life outside the solar system.
