NASA has been trying to find exoplanets that can habituate life in the case humans have to leave earth. The several missions from the agency have seen many of the potential candidates as well. However, the mutual effort of Hubble and Kepler telescopes may have spotted the first exomoon. While nothing has been confirmed yet, the celestial object is expected to be a colossal moon of some planet. According to the estimates, the object in question is situated 4000 light years away from Earth. The space component orbits an exoplanet that is bigger than Jupiter and the moon is bigger than the Earth itself.
As said earlier, NASA has been hell-bent on finding some exomoons from the nearby galaxies, but the task has not been that easy. Compared to exoplanets, many of which have been found by various missions in the past years, exomoons are rare to find. It means that there aren’t many exoplanets that have a moon, at least in the area easily discoverable by the telescopes from NASA. This new exomoon was revealed in a study that was conducted and published by Alex Teachey and David Kipping, who are two researchers at Columbia University.
The researchers themselves have mentioned that the study requires better analysis and further confirmation to be held true. It is also clear that the distance of the exoplanet is going to make things hard for the research team, as better telescope and optical features would be required for the extensive study of the same. A bunch of methods were used to confirm the existence of the exomoon and the planet which it orbits. One of the methods was to make sure that the light of the star was dimmed when the exomoon got to the front of the element. While these are prominent clues, the researchers will be looking for advanced confirmation.
