Exoplanets , those that revolve alien adept far beyond the reach of our Solar System , arefairly unmanageable to find . Thankfully , the Kepler infinite observatory has had its buttony centre on the drab , wispy depths of the world for some time now , and as a result , researchers now know there are at least 5,000 of the surreptitious planet out there .
As a new study submitted toThe Astronomical Journalreveals , NASA ’s researchers may have miss a few along the way of life : After look through a sizable chunk of Kepler data herself , astronomy student from the University of British Columbia ( UBC ) , Vancouver , has likely fall upon four exoplanets of her own , including a very rare “ warm Neptune . ”
catalogue as Kepler Object of Interest ( KOI ) 408.05 , this planetary campaigner – one waiting for official substantiation of its existence – is locate 3,200 faint - years aside from Earth , and it is found within the so - call in “ inhabitable zone ” of its star . This means that fluid H2O may be present on the surface , and as scientist are becoming astutely cognizant , wherever there is H2O , there is life .
“ Like our own Neptune , it ’s unlikely to have a rocky surface or oceans , ” Michelle Kunimoto , a impertinently - mint UBC physics and astronomy graduate and lead writer of the subject , said in astatement . “The exciting part is that like the large planet in our solar system , it could have large moons and these moons could have liquid water supply oceans . ”

After sifting through reams of Kepler data , Kunimoto realized that there were diminished “ blips ” or data points that NASA ’s own researchers may have overlooked . These data point took the shape of transits , short dips in the boniface principal ’ brightness that point a satellite may have crossed in front of them . In some case , this can be triggered by aswarm of fragmenting comets , but in this case , Kunimoto is certain that the four objects are brand new exoplanets .
The first three vary in size : Two are the size of Earth , and one is somewhat larger than Neptune ; all three arena very nigh to their host star . Based on their orbits and size , their equilibrium temperatures – those generated alone by incoming solar radiation being remitted from the airfoil – range from 463 ° C to 1,381 ° C ( 865 ° F to 2,518 ° F ) , signify that they are improbable to contain much fluid water , if any .
The so - name warm Neptune , however , has an vestibular sense surface temperature of around -21 ° C ( -5.8 ° atomic number 9 ) . Although this is below the freezing point of water , this is very similar to Earth ’s equilibrium temperature . Earth is far tender than this thanks to its wooden-headed atmosphere create a warming greenhouse effect , and the same could be operate on KOI 408.05 .

The squad also propose that any moons this major planet may have will also shack within the same ardent solar radiation gasbag . They liken these hypothetical moonshine to Pandora from the pic “ Avatar , ” although theforest moonshine of Endorfrom the “ Star Wars ” franchise could be just as applicable .
At least four antecedently support exoplanets already orbit this special whiz , meaning that KOI 408.05 is potential to be the system ’s fifth planetary member . Although it still need to be verified , it appear that yet another likely inhabitable exoplanet has been found – and that ’s always something to observe .
