The study suggests that some exoplanets could see the Earth

“In our quest for life in the universe, we ask a slightly different question in this research,” said Lisa Caldeneger, associate professor of astronomy at Cornell University College of Arts and Sciences and director of the Cornell Carl Sagan Institute. Video shared by the company.

“We ask, who really could have found us? Who could have discovered that the earth draws life from their abode?”

Kaltenekar and Joshua Pepper, associate professors of physics at the University of Leh, have identified more than a thousand stars, such as our Sun, which orbit like Earth, which may support liquid water on their surface. Astronomers refer to this distance as the habitable zone.

To be clear, no such planets have ever been found or confirmed around these stars.

Within 300 light-years from Earth, those potential planets could directly see Earth and the life that thrives on it.

“It takes a certain amount of time to see the Earth move in front of its star, the Sun. Then once a year, if you see the Earth moving in front of the Sun in your view, the Sun is a little less bright,” Kaldenegar said.

“So you know a planet orbits it and you know it’s at the right distance, so it can contain liquid water, which is one of the most important things in life.

“So, in 300 light years, we have identified the closest thousand stars. Approximately, this may have already found us. Maybe there is life in the universe. Maybe they have already discovered us. What do they think?”

Life is outside the Earth and if we have our vision, we can use the sunlight to see our atmosphere and understand more about our planet as the Earth moves in front of it.

“If visitors come looking there, they can see signs of a biosphere in the atmosphere of our light blue dot,” he said, “and some of the brightest of these stars can be seen in our night sky even without telescopes. Or telescopes.”

The “light blue dot” is the name of an icon, Cornell astronomer Carl Sagan suggested that NASA’s Voyager 1 probe should move the Earth from a distance of 3.7 billion miles to the edge of the solar system. Picture taken on February 14, 1990.

The search for life

Passing a planet in front of its host star is called a transport, and it is one of the main methods used by astronomers to detect exoplanets using terrestrial and space-based telescopes.

When NASA’s James Webb Space Telescope launches next year, it will be used to explore the atmospheres of the Exoplanets using this method, and astronomers can use that data to help classify the atmospheres of the Exoplanets.

NASA’s Planetary Hunting Transparent Exoplanet Survey Satellite (TES), which has been observing nearby bright stars since its launch in 2018, will begin a new phase of its mission in 2021. The plane of the Earth’s orbit around the Sun. The Tess spacecraft will mainly turn to its side to pay more attention to the sky.

The list of stars compiled by researchers from Tess’s star list can be used as a quest to replace exoplanets.

An eclipse is basically the place where you can see the exoplanets that hold the earth, because from their position, you can see the earth as it passes in front of the sun.

“Only a very small portion of the exoplanets will be roughly aligned with our vision, so we can see their traffic,” Pepper said.

The star systems that could see the Earth when life first began on our planet are different from the signs of life on our planet now – as well as the star systems that could see the Earth in the future, the researchers wrote in their paper.

“If we see a planet with a vibrant biosphere, we will be curious about whether anyone sees us or not,” Kaldenegar said. “If we’re looking for brilliant life in the universe, it might want to find us and communicate with us. We have created a star map of where we should look first.”
