“#Researchers find some planets beyond solar system can view Earth<\/strong>”
\n<\/p>\n

\n More than 4,500 exoplanets have been discovered so far, with only a small portion thought to have the properties to contain life. A new study suggests that some of those planets and any extraterrestrial life that lives on them can see us too.<\/p>\n

The research, published in the scientific journal Monthly Notices of the Royal Astronomical Society,<\/a> has identified 1,004 stars that are similar to our sun that may have Earth-like planets in their orbit. These star systems have a \u201cdirect line of sight to observe Earth\u2019s biological qualities from far, far away,\u201d according to a statement<\/a> accompanying the research.<\/p>\n

\u201cLet\u2019s reverse the viewpoint to that of other stars and ask from which vantage point other observers could find Earth as a transiting planet,\u201d Lisa Kaltenegger, associate professor of astronomy and director of the Carl Sagan Institute at Cornell University, said in the statement.<\/p>\n

\u201cIf observers were out there searching, they would be able to see signs of a biosphere in the atmosphere of our Pale Blue Dot,\u201d Kaltenegger added.<\/p>\n

Sagan, one of the world\u2019s most famous astronomers, was instrumental in the \u201cPale Blue Dot\u201d<\/a> photo taken by NASA\u2019s Voyager 1 spacecraft in February 1990, looking at Earth from more than 3.7 billion miles away.<\/p>\n

The findings, while thought-provoking, are limited by the amount of time each of the star systems can observe Earth, the researchers noted. Only 508 of them are able to \u201cguarantee a minimum 10 [hour] long observation of Earth\u2019s transit,\u201d the researchers wrote in the study.<\/p>\n

The study\u2019s co-author, Joshua Pepper, said \u201conly a very small fraction\u201d of exoplanets could align just right so those on Earth could see their transit, but all of the 1,004 identified in the paper can see us, potentially \u201ccalling their attention.\u201d<\/p>\n

It\u2019s also possible the life on these planets could exist for billions of years, given the properties that they are believed to possess, a sign they need additional study.<\/p>\n

These planets have been observed due to transit observations, or when an object crosses in front of a star, dimming the star, thus allowing astronomers to see it. This type of observation will be expanded when NASA launches its James Webb Space Telescope in October 2021. If an extraterrestrial civilization had its own advanced equipment, similar to the JWST, they may be able to see us as well.<\/p>\n

\u201cIf we found a planet with a vibrant biosphere, we would get curious about whether or not someone is there looking at us too,\u201d Kaltenegger explained. \u201cIf we\u2019re looking for intelligent life in the universe, that could find us and might want to get in touch. We\u2019ve just created the star map of where we should look first.\u201d<\/p>\n

In June, a separate group of researchers suggested<\/a> there are 36 \u201cintelligent civilizations\u201d in the Milky Way galaxy, a calculation the experts have dubbed \u201cthe Astrobiological Copernican Limit.\u201d<\/p>\n

A separate study published<\/a> in mid-May suggested that not only is the \u201cuniverse teeming with life,\u201d but that it\u2019s \u201cthe favored bet.\u201d\n <\/div>\n
