There are around 2,000 moon-to-Jupiter sized planets for each main sequence star in their observations, the researchers wrote, which equates to trillions of stars per galaxy.
For the purposes of their study, the researchers relied on the gravitational microlens technique, which relies on the gravitational force of distant objects to focus light from a star.
"We show that quasar microlensing provides a means to probe extragalactic planets in the lens galaxy, by studying the microlensing properties of emission close to the event horizon of the supermassive black hole of the background quasar, using the current generation telescopes", the researchers write.
Kenyan opposition figure charged with treason over Odinga's 'swearing in'
The government took three private television channels off the air on Tuesday as they began to cover of the opposition ceremony. His supporters in the opposition stronghold of Kisumu city in western Kenya clashed with police, who fired tear gas at them.
NZ knocked out of Sevens by Fiji
Four minutes later, Naduva, the man in the only green boots in the final, ran around the Blitzboke defence to level scores 5-all. Wales scored another two tries in the second half to just the one from Russian Federation to win 33-7 in the end.
Stop right now! The Spice Girls have reunited for "new opportunities"
Melanie Chisholm has said the Spice Girls are getting back together because the world needs a little more girl power right now. They last officially performed as the Spice Girls for the London 2012 Olympics Closing Ceremony.
The new discovery has given some significant information about our solar system by extending the limitation of previously formed data on the Universe. This, in turn, helps the Astrophysicists to determine the mass of the planet. Since 2014, the Kepler has continued to search for planets outside of Earth's solar system while coming across young stars, supernovae and "other cosmic phenomena".
"This is an example of how powerful the techniques of analysis of extragalactic microlensing can be".
'However, we are able to study them, unveil their presence and even have an idea of their masses. This is the first time that planets are being located in other galaxies. "This is very cool science", Guerras added.
More than 2,000 planets were detected, majority wandering through space not orbiting a star or orbiting between several stars, National Geographic reported. But so far all of those planets have been in our general celestial neighborhood, within our galaxy, the Milky Way. These newly-discovered extragalactic planets, however, are located some 3.8 billion years away.
In the university's announcement, Guerras said "there is not the slightest chance of observing these planets directly" because of the distances involved.
Up until now, while we've been pretty certain that planets must exist in foreign galaxies, we haven't actually be able to spot them-not because they're hiding, but simply because there's a limit to how far our sensors can reach.
