Earlier this year, Inquisitr reported on the discovery of a huge planet that floats just 20 light-years away from Earth. Unlike most planets, this celestial body does not orbit a star and was found lost by the cosmic darkness detected by the radio telescope.
Now, astronomers have announced that they have found two more dishonest planets in our galaxy – uncaramed journeys that live on the eternal night, striving for single goals.
Conformable The New Scientist, the two floating free planets were discovered by Polish astronomers at the University of Warsaw who detected planetary organisms in data from the Optical Gravitational Lensing Survey (OGLE) at Las Campanas Observatory in Chile.
"The theories of planet formation predict the existence of floating free planets discharged from their parent systems." Although they emit little or no light, they can be detected during gravity microlensing events, "explains the team in a new study published last week on the arXiv preprint server .

While most of the planetary discoveries are made using a technique called the transit method – looking for diving in the glow of a star to see a planet orbiting passing in front of it, Inquisitr previously reported – finding rogue planets is much more complicated.
This is because these celestial dissatisfied nomads are not tied to a star they can transit and temporarily diminish, thus running astronomers to their presence. In their case, scientists rely on gravity microlensing – an astronomical phenomenon that shines the light on hidden planets when they happen to cross paths with starlight from large stars.
When a planet moves in the way of a remote starlight, its gravitational pull causes the light of the stars to twist and distort, notes Futurism. This effect can be observed by earth observers and can lead to the detection of exoplanets that would otherwise have gone unnoticed.
The method was used before to find hidden planets outside our solar system – and even beyond the boundaries of the marshland, reported by Inquisitr earlier this year.
The same technique helped OGLE to lift one of the rogue planets newly discovered on April 16, 2017. Detection was later confirmed as a planetary organism by observation observations from other observatories, reports Motherboards.
Dubbed the OGLE-2017-BLG-0560, this object is enormous and could be "a Jupiter-mass planet in a galactic disc or a dwarf bullet in bullet," with up to 20 times the Jupiter table, astronomers say.
Intrigued by this exciting discovery, the team chuckled through the OGLE archive and came across another dishonest planet. Known as OGLE-2012-BLG-1323, this planet was initially detected on August 21, 2012, but it simply fell through cracks and was overlooked so far.
Unlike 2017, this dishonest is considerably smaller – in fact, it is the smallest planet ever found to wander the universe at peace – and has an estimated mass ranging from that of the Earth and Neptune.
Only about a dozen dishonest planets have been discovered so far, though astronomers suggest that the Milky Way could host more planets without stars and current stars.
