It all started when Oumuamua, a mysterious celestial entity was discovered by a European spacecraft. Astronomers were surprised to see the first interstellar object to have ever appeared in our solar system. Relying upon the observational data collected by the spacecraft, a team of international astronomers were able to identify four dwarf stars. These are believed to be the possible home of this interstellar object. As per the evidence, Oumuamua was ejected into space by any of these planets, about approximately a million years ago.
However, it’s still a debate whether such a planet revolves around any of the stars that have been already identified by our scientists. Even scientists aren’t sure of that. It is also a possibility that we don’t really know the planet yet, that gave birth to this ultimate celestial mystery.
Groups of scientists have even tried tracking Oumuamua back to its origin only to fail at their attempts. However, the recent data published by the Gaia Probe; belonging to the European Space Agency, revealed some valuable insights about the phenomenon. Gaia is the space observatory dedicated towards the collection of information regarding the stars in our Milky Way Galaxy.
According to an astronomer Alan Jackson, this new data received from Gaia has provided a clearer picture of far away stars and helps in monitoring their movement. Therefore, it is just a matter of time when the scientists would be able to successfully track the origins of this mysterious comet.
According to astronomers, Gaia has been able to collect detailed information about over 7 million stars, along with another 220,000, as per mentioned in the astronomical literature. After carrying out some specialised calculations, Gaia has identified four stars that have possibly come within a couple of light-years of Oumuamua within the last 7 million years. One of them is HIP 3757, a red dwarf star, while the other is HD 292249, which resembles our Sun. There is not much information available for the other two stars.
The recent research is obviously not the final nail on the coffin, when it comes to speculation about Oumuamua’s origins. It is mainly because; the research is unable to figure out the native star from which this comet has originated. Possibilities of Oumuamua coming from an entirely different star in furthest corner of our space, is also undeniable. Scientists feel that sending a spacecraft near Oumuamua can answer all those unsolved questions. But it will take considerable time.
