Is human really the only intelligent creature in the universe? Is there life on other planets in such a vast universe? Is it that we didn’t find out or does it really don’t exist. Recently, a research team at Cambridge University discovered a planet similar to the earth that can give birth to life. This group of extrasolar rocky planets has been selected as the “best point” for searching for extraterrestrial life.
The team found that the planet across the Milky way has a lot of ultraviolet light on its surface, and is located in the habitable area of the host star, which means that it is likely to have water resources on its surface.
This habitable area, also known as the “Goldilocks” area. The living area is the orbit around the star, in which the planets can form liquid water. In order for liquid water to appear on the surface, the temperature of the star must be positive. The boundaries of residential areas are important. If a planet is too close to its star, it will experience the effects of runaway greenhouse gases like Venus. But if it’s too far away, the water will freeze, just like on Mars.
The Cambridge team found that the probability of life forming on rocky planets is related to the light emitted by their host stars.
“The new classification of planets brings us closer to answering the question of whether we exist in the universe,” the researchers suggest On the ground, ultraviolet light can cause a series of chemical reactions, forming the basis of life. Researchers have discovered a series of planets whose host stars emit enough ultraviolet light to start living like earth.
It is known that the rock group that the team pinpointed is also within the habitable range. The researchers measured the rate of formation of biological lumps in ultraviolet and dark environments, which began to grow on ancient earth from the same chemical: hydrogen cyanide and hydrogen sulfite in water. Hydrocyanic acid interacts with other elements in many ways and generates RNA by ultraviolet radiation. Dr. Paul Reimer, one of the co authors of the study, said the work would allow us to narrow down the best place to search for life.
Professor Sutherland, from the molecular biology laboratory of the Medical Research Council, said: “it’s nothing to be prepared for life. Even under favorable conditions, we don’t know the possibility of the origin of life on other planets.”
NASA launched the Kepler space telescope in 2009 to find orbiting planets around extrasolar stars. Satellites often look for planets similar to earth, which means they are rock in the habitable region of a star or in the orbit of a blonde. If the planet is in a habitable area, that means it won’t be too hot or too cold, which is a key condition for life.
In 2014, when the telescope discovered the exoplanet kepler-452b, 1400 light-years away, it was exciting. Because this exoplanet has many similarities with our planet, it is also known as the earth upgrade. The planet is too far away for current exploration technology. Scientists are not sure if the planet will survive, but NASA says if the plants are moved there, they are likely to survive. According to the latest estimates, as many as 700 million earth like planets can be observed in the universe.
