Can life live on any other planet?
Can life live on any other planet?
The Kepler mission—a space observatory launched by NASA in 1997 to search our galaxy for just these kinds of Earth-like planets—has found one candidate that meets both requirements, Kepler-452b. So the chances of life on another planet are high. However, we have no direct evidence yet of life anywhere other than Earth.
Is it possible for life to exist in other planets in the solar system?
But what we don’t know fills volumes. Observations from the ground and from space have confirmed thousands of planets beyond our solar system. Our galaxy likely holds trillions. But so far, we have no evidence of life beyond Earth.
Which planet can support life only?
Earth
Earth is the only planet known to support life.
How many planets can support life?
We may expect to find either 2.625 or 1.4 billion planets with the potential to create and maintain life. The exact number is not important as we are dealing with an estimate that contains large uncertainties.
Can life survive on Mars?
After mapping cosmic radiation levels at various depths on Mars, researchers have concluded that over time, any life within the first several meters of the planet’s surface would be killed by lethal doses of cosmic radiation.
What are the 7 signs of life?
The seven characteristics of life include:
- responsiveness to the environment;
- growth and change;
- ability to reproduce;
- have a metabolism and breathe;
- maintain homeostasis;
- being made of cells; and.
- passing traits onto offspring.
Is there life on other planets Brainly?
There is a total of 8 planets in the solar system but living beings have been observed only on one planet and that is the earth. Scientists have not witnessed any signs of life on any of the other 7 planets yet. Many people want to learn why is life not possible on all planets.
Why is life not possible on all planets answer?
Answer: A smaller amount of metal makes the formation of planets much less likely, under the solar nebula theory of planetary system formation. Any planets that did form around a metal-poor star would probably be low in mass, and thus unfavorable for life.
What other planet can humans live on?
Then, just last year, scientists discovered another Earth-like planet orbiting one of our closest neighboring stars, Proxima Centauri. Currently, this planet is the best candidate we have for supporting human life.
Why Earth is the only planet that support life?
A special planet: the habitable Earth What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
