TRAPPIST-1 would like to remind you that it was drinkin ’ beer while you were still rompin ’ around in your diaper — or whatever old mass say . The ultracool dwarf mavin system , which first wasannounced back in February , has garner a lot of interest because it harbour seven world - size major planet . At least three of those major planet are within the habitable zone that can sustain liquid water and potentially , life . As we ’re all clamoring to get off this satellite understand this exotic system , a duo of researchers has figured out some pretty salient selective information about its asterisk ’s age .
The team of astronomers used information gathered from various scope to determine TRAPPIST-1 ’s age , which they estimate isbetween 5.4 and 9.8 billion years quondam . Our Sun is a whippersnapper by equivalence : it ’s only about 4.5 billion age old .
“ We do n’t get the birth certificate of stars when we find them , we just see how they are today , ” University of California , San Diego astronomer Adam Burgasser , a co - generator on the research , which is set to be published on The Astrophysical Journal , told Gizmodo . “ So we had to look for clue that might change on the star over time . ”
Burgasser and his fellow worker , NASA Exoplanet Exploration Program deputy platform scientist Eric Mamajek , used various air of known data about TRAPPIST-1 to assemble together a statistical constraint , which is fundamentally a damn good educated guess about the star ’s eld . For clues , the team looked at factors like the f number of TRAPPIST-1 ’s orbit around the Milky Way , its atmosphere ’s composition , and more .
Understanding more about this foreign star organization just for the sake of it is pretty nerveless — after all , TRAPPIST-1 is so delightfully weird . But understanding the system of rules ’s age could have some moderately braggy deduction for life on the planets , if there is any .
“ sympathise age is jolly important important when you think about the growth of planet themselves , and potentially life on these planet , ” Burgasser aver . “ It took about four billion years for complex life to organise on Earth , so if we ’re thinking about if there ’s any life on these planet , how long has it been there to evolve and develop . ”
plainly , the question of whether or not the TRAPPIST-1 planets can support life is up for debate . Someastronomers think that spirit probably could n’t sustain itself on these planets , due to their close proximity to their host mavin . one thousand dwarf stars like TRAPPIST-1 are known for spatter off heavy solar flares , and some researchers think this could have gnaw the planets ’ atmospheres . Also , after being so close to their star for billion of years , it ’s possible that any water on these planets has boil away , due to eons of bombardment with mellow - vigor radiation . Of course , other researchers thinkthere ’s a shot life-time on these major planet could exist in sealed places , so at this percentage point we ’re still left with more questions than answers .
Hopefully , the launch of swelled telescopes like James Webb will assist in our understanding of alien systems like TRAPPIST-1 . Now that we know it ’s old , it seems there are even more mysteries out there waitress to be solved .
