Astronomers have found thousands of planets in a galaxy outside our Milky Way galaxy. This is the first occasion when that planets are being situated in different systems.
The planets are changed in measure; some as little as the Moon while some as large as Jupiter.
Around 2,000 unbound planets were found in the midst of the stars of the faraway galaxy arranged 3.8 billion light-years. Up until this point, there has been no proof of planets in different universes, as indicated by Science Alert.
This revelation was made by the researchers at the University of Oklahoma utilizing the system referred to as gravitational microlensing and also data from NASA’s Chandra X-beam Observatory.
It’s a hard assignment to discover exoplanets inside our own Milky Way galaxy but with the microlensing method, which was first anticipated by Einstein’s hypothesis of general relativity helped in finding these exoplanets.
Up until now, microlensing is the main path used to identify the most diminutive and removed planets which are arranged around thousands of light-years from Earth.
“As a planet orbits a star, the gravitational field of the system can bend the light of a distant star behind it,” Science Alert reported.
It’s comprehended what it would appear that when only two stars are there, but when a planet enters the group, it creates unsettling influence in the light which contacts us which help in recognizing the exoplanets.
Till now, 53 exoplanets have been found in the Milky Way utilizing this procedure. An all the more intense method was required to discover planets situated at a more far off district from our galaxy.
Space experts Xinyu Dai and Eduardo Guerras from the Oklahoma University investigated a quasar six billion light-years away named as RX J1131-123, which is known as outstanding amongst other quasars introduce in the sky.
“The gravitational field of a galaxy 3.8 billion light-years away between us and the quasar bends light in such a way that it creates four images of the quasar, which is an active supermassive black hole that’s extremely bright in X-ray, thanks to the intense heat of its accretion disc,” a report in the Science Alert said.
Strange lines of energy shift in quasar’s light were found by the researchers, which must be clarified by the planets in the galaxy lensing the quasar.
“We are very excited about this discovery,” Dai said in a statement.
“This is an example of how powerful the techniques of analysis of extragalactic microlensing can be. This galaxy is located 3.8 billion light-years away, and there is not the slightest chance of observing these planets directly, not even with the best telescope one can imagine in a science fiction scenario,” Guerras said in a statement.
“However, we are able to study them, unveil their presence and even have an idea of their masses. This is very cool science,” he added.
“However, we can ponder them, reveal their essence and even have a thought of their masses. This is exceptionally cool science,” he included.
