Yes, interesting! A free-roaming planet not orbiting a star.
But going back to earlier this year, there was a discovery of planets in a galaxy far far away some 3.8 Billion light years away using gravitational lensing techniques. A very lucky and rare alignment of two galaxies at different distances. One jaw dropping conclusion from the observations was "Furthermore, the scientists said results suggest that in most galaxies, there are about 2,000 free-floating planets for every star. " I mean ... what?! ... wow! www.scientificamerican.com/article/did-we-just-find-exoplanets-in-another-galaxy/ The universe just gets crazier the more we learn about it.

--- basically, the galaxy between us and the far galaxy acted as a gravitational lens causing the light from the far galaxy to bend around it. This created 4 'images' of the far galaxy. And each image was subtlely different - and by far the best way to explain these differences is a multitude of free planets in that galaxy all contributing to initial gravitational distortions in the light. The best fit explanation, assuming 'typical' sized planets was for there being trillions of them.
