Are aliens real? Astronomy no Harvard they suggested that a recent unknown object might be an alien spacecraft investigating the Earth, and now there is a study on Massachusetts Institute of Technology (MIT) suggests using a high power laser how to "lighthouse"attract alien life, if it exists in our galaxy.
Investigation MIT, recently published in 2008 Astrophysics magazine, suggests that a laser of 1 to 2 megawatts, centered on a large telescope (29 to 45 meters), could act as a "the planet's light of light"calling for potential alien life up to 20,000 light years away.
"It would be a difficult project, but not impossible"said study author James Clark in a statement.
"Today's developed lasers and telescopes can create a signal for the astronomer to see our star and see an unusual spectrum immediately. I do not know if intelligent creatures around the sun would be their first guesses, but this will definitely attract more attention."
According to Clarke, the laser star stands out from solar power and could be used to send text messages using the "legumes", similar to Morse code.
Of course, to receive a signal, there must be alien life.
Around TRAPPIST-1b, a star that is about 40 light years away, has three exoplanets (planets that stop outside our solar system) that are potentially habitable.
According to Clark, the laser machine's alien life should be built on the hill to reduce the amount of atmosphere that the beam should pass before it shines in the room.
"Oumaamua"Is the life of Aliens nearer the Earth?
"Oumaamua"This is the first known interstellar object that entered our solar system and was discovered in October 2017 in the Hawaiian Telescope system after it was discovered that"Oumaamua"It was not a comet, many took to Twitter to share their thoughts that this object was in fact a sign of extraterrestrial life.
New article by researchers from Harvard Smithsonian Astrophysical Center They raised this opportunity.
"Oumuamua can be a fully functional probe that was brought to the ground by foreign civilization"wrote the researchers in an article that was sent to the magazine Astrophysical magazine letters.
Researchers from Harvard suggests that "Oumaamua"It could be a sunny sail"floating interstellar space, for example, debris stored from state-of-the-art technological equipment"
Other astronomical experts, however, disagree. Alan Jackson, from Planetary Science Center no Toronto University, Scarborough, March published an article that suggests that "Oumaamua"It looks like an asteroid or comet rather than a sunshine that comes with a two-star system.
