"These small planets are the best candidate for the signature we observed in this study using the microlensing technique", said Dai.
"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.
We tend to assume that other galaxies have planets - after all, why should the Milky Way be unique? - but this could be the first, albeit indirect, evidence for these distant worlds.
Usually astronomers find planets through one of two ways: watching a planet dim the light of a star as it passes across the star - the transit method - or watching a star wobble due to planets orbiting around it - the radial velocity method.
Scientists have long thought that exoplanets-planets beyond the solar system-were restricted to the confines of our Milky Way.
The microlensing technique was initially used to detect planets outside of our solar system.
University of Oklahoma postdoctoral researcher Eduardo Guerras said: "This is an example of how powerful the techniques of analysis of extragalactic microlensing can be".
Of course, the astronomers have not seen these planets directly, and perhaps, they will never be able to do it. In order to discover planets in a galaxy which is further away, scientists would have to use something stronger than the light of a single star.
