It happened eight years ago, but it has yet to be revealed. at 2014, a huge fireball burned in the sky of Papua New Guinea. Actually it was about fast moving object From another star system, according to the document Published by the US Space Command (USSC).
In other words, the burning object was confirmed to be the first interstellar object to reach our solar system and enter the Earth’s atmosphere, a confirmation that was only possible after study It was published by researchers at Harvard University in 2019.
Researchers Amir Siraj and Abraham Loeb, of the university’s Department of Astronomy, determined that the meteorite originated in an unbound hyperbolic orbit, that is, outside our solar system, with a confidence of 99.999%. Apparently, it all started after the discovery of Oumuamua, when Loeb encouraged Siraj to search a database fireballs The NASA meteorite affects potential interstellar objects.
In this way, the researcher discovered that the meteor, which exploded near the island of Manus on January 8, 2014, was traveling at a speed of more than 209 thousand km / h. The data also indicates that it originated in the “deep interior of a planetary system or star in the thick disk of the Milky Way.”
Subsequent analysis and study by the USSC confirmed that the velocity estimate given in the study was accurate enough to indicate an interstellar path. The data was then collected in Department of Defense sensors intended to monitor the skies for nuclear explosions. As Siraj told the media, vicehe was hoping to be able to search for meteor fragments that might be at the bottom of the ocean:
It’s going to be a big task, but we’re going to take a closer look at it because the prospect of getting your first piece of interstellar matter is exciting enough to check it out thoroughly and talk to all the world’s experts on ocean-going expeditions to recover meteorites.
Con todo, también expresó sus dudas sobre el éxito de la búsqueda, tanto por el pequeño tamaño del meteorito como por el hecho de que sus piezas probablemente estaban esparcidas en un área grande. [ LiveScienceAnd Archives]
