Astronomers May Have Spotted the First Known Exoplanet in Another Galaxy:
· Scientists have confirmed observations of the first-ever exoplanet in another galaxy, 28 million light-years away. Though this planet is incredibly far away, it will help scientists understand how planets form around their stars in different gravitational conditions, especially since its orbit is around a black hole. Normally, the identification of an exoplanet is done when the continual measurements of light coming from a star in our galaxy are briefly interrupted consistently, represented by the orbit of the exoplanet eclipsing it for a moment. At 28 million light-years away, this strategy was repeated, but with X-rays instead of visible light. Through this investigation, the planet was found to be of similar size to Saturn and seemed to be orbiting around a neutron star (precursor to a black hole) or a black hole, almost twice the distance of Saturn from the sun. However, the orbiting patterns found cannot be confirmed until 70 more years pass, where the planet will pass in front of the star it orbits.
