Aliens Might Have Already Found Us? Extraterrestrials Might Have Already Known our Existence
While earthlings are having extensive efforts to search for extraterrestrial life, we should also point out that aliens, if they do exist, might have been hunting us, too. Not to mention another footage of UFO sighting was reported in April 2021. Meanwhile, a study solidifies this idea by stating that there are over 1,000 stars in the proximal degree that might have already spotted our planet and also figured out that we, and all other living creatures, exist.
According to Lisa Kaltenegger, director of the university’s Carl Sagan Institute and an associate professor of astronomy at Cornell, “If observers were out there searching [referring about the planets orbiting these stars], they would be able to see signs of a biosphere in the atmosphere of our Pale Blue Dot,” She also added that “…we can even see some of the brightest of these stars in our night sky without binoculars or telescopes.”
In addition, over 4,000 exoplanets were found by astronomers using the transit method, which is when an observer notices a dip in the star’s brightness, mainly because space objects, such as planets, passes the observer’s degree of view of the sta. The best example of this is when the light of the Sun dims because Mercury or Venus passes. This technique has been greatly used on NASA’s Kepler space telescope and is being passed to the Transiting Exoplanet Survey Satellite (TESS), its successor.
In the near future, researchers will get the chance to observe the atmospheres of these nearby planets and get a glimpse of potential indications of life. This work will just be one of the series of tasks of the James Webb Space Telescope of NASA, which costs $8.8 billion. It’s scheduled to launch in space before 2021 ends. Aside from this magnificent invention, another investment for space equipment is the Giant Magellan Telescope that will do such a similar job.
With her co-author Joshua Pepper, an associate physics professor at Lehigh University, Kaltenegger believed that our planet is the “target of a transiting-planet survey rather than the source of one.”
Several scientists analyzed the gathered data of Gaia, Europe’s star-mapping spacecraft, and TESS, searching for stars about 326 light-years away. However, they are looking for the ones that are arranged with the ecliptic, which is the degree of Earth’s orbit around the Sun. This kind of arrangement is crucial to observe our home planet traverse the face of the Sun.
Moreover, this quest got the credit for finding “1,004 qualifying main-sequence stars” — which, just like the star in the solar system they, “fuse hydrogen into helium in their cores.” Surprisingly, 508 of those recorded stars ensure at least 10-hour-long surveillance of Earth’s transit beyond the sun’s plane. This is suggested by Pepper and Kaltenegger in the recent study they wrote in the Monthly Notices of the Royal Astronomical Society: Letters’ journal.
Fresh equipment for the extraterrestrial quest
The latest issues only talked about stars and the scientists involved are uncertain about the number of planets that orbit those 1,004 suns pointed out by the two aforementioned professionals, Furthermore, they’re also unsure about which of them have the potential to host life, but the good thing is that Earth had an investment in advance technological equipment like TESS, which is incessantly working in order for us to understand the mystery of the vast universe, especially if aliens are real and have they already reached us, saw us, and know that we exist.
Lastly, Kaltenegger stated that “If we’re looking for intelligent life in the universe that could find us and might want to get in touch, we’ve just created the star map of where we should look first.”
