This is how visitors can search for human life

In research About heavenly life, we are often the same to do the meditation. But Lisa Kaltenegger, an astronomer at the University of Cornell, wanted to know who might be looking out there. we. “To whom can we be strangers?” He asks.

That’s why Kaltenegger enlisted Jackie Faherty, an astronomer who works at the Hayden Planetarium, part of the American Museum of Natural History, in New York City. Together, they undertook the task of identifying stars that could be in a strange land where inhabitants — past, present, or future — would have the opportunity to discover the Earth as a continuous exoplanet. This means that their planet would have the right location to see the light of our sun as the Earth passes, or passes through, in front of it. This is one of the most effective ways in which Earth’s planets can orbit the planets in orbit around the sun, forming tiny particles that can be seen by celestial bodies.

In June, Kaltenegger and Faherty announced their results in Nature and the vast array of stars that have had, or will have had, the right way to find our planet. He identified more than 2,000 stars, using time from 5,000 years ago, when civilization on Earth began to explode, until 5,000 years later. Not only the files a learning providing useful exoplanet hunters by pointing to the stars to which they should pay attention, also provides a unique form — as well as the opposite, unmistakable appearance in our universe. “I felt like I was going to see it a little bit,” says Faherty, recalling the occult of over-pressure. “Do I want to live in a world where it can be found?”

Bruce Macintosh, a nonprofit astronomer at Stanford University, states: “It’s a great science fiction novel, considering the dynamics of the universe. When the first studies of its kind detect changes in the number of stars that move in time, they are simply the result of an earlier study using only space in the sky. “Now we can make a video showing how the universe will look 5,000 years from now in the future, we think all the stars are twinkling as the planets move,” he says.

The new results were made possible by a recent release from the European Space Agency’s Gaia mission, a spacecraft aimed at mapping three images of space and the flight of one billion stars. In addition to the electronic program that Faherty used to compare stars, he and Kaltenegger found 2,034 real stars in the Earth’s orbit. Almost all of them, any living thing on the planets that orbit the stars, with sufficient expertise, can detect the presence of the Earth for at least a thousand years. Kaltenegger says: “In the cosmic era, then blip on the radar,”

But in the course of human life, they say, it gives astronomers more time to develop the necessary tools to keep an eye on another planet. Kaltenegger and Faherty hope that astronomers will use the book to discover new planets, especially around orbiting stars. Since then, major services like NASA future James Webb Space Telescope, which is to be established by the end of the year, can be used to study astronomy and look for signs of life. “This is a repository of planets just waiting to be discovered,” says Kaltenegger. “I’m really looking forward to what people have found.”
