Scientists have serendipitously discovered what is possibly the faintestgalaxyever seen after making a literal in their telescope coordinates . The strange physical object is seemingly made entirely from spread - out gas and does n’t contain any visible stars .
The new Galax urceolata , which scientists have name J0613 + 52 , was first detected when a typo in the coordinates channelise the Green Bank Telescope ( GBT ) in an unintended counseling . Scientists caught the fault during a unremarkable standardisation against theArecibo telescopein Puerto Rico , but the squad was surprised to discover that the inadvertent observation tell apart an separated and unrecorded physical object known as a saturnine primal galaxy , according to research presented Jan. 8 at the American Astronomy Society ’s annual coming together .

" We have an target whose evolutionary history is undisturbed by anything else around it . An object that has formed stars of its own treaty , not as the result of a gravitational fundamental interaction with other objects,“Karen O’Neil , the tether astronomer on the discovery from the Green Bank Observatory in West Virginia , told Live Science . The galaxy ’s complete want of neighbors , coupled with the extremely spread - out gas within the galaxy think that comparatively few stars are likely to have take form . Any star topology that may have been stand are n’t seeable , which makes the aim dark and therefore peculiarly difficult to discover with current official document .
O’Neil estimates J0613 + 52 is around 260 million light - long time away , placing it well alfresco of theMilky Wayand into the region of space known as the Nearby Universe . However , despite the difficulty of observing and measuring this dark physical object , the team has already delineate several comparing with our family galaxy .

" We have sex the full amount of neutral hydrogen — it ’s a little routine less than theMilky Wayhas , " O’Neil said . " The total mass of the extragalactic nebula is also similar to the total mass of the Milky Way . But what that people is made up of , we ’re not sure yet ! "
However , scientist still do n’t have enough datum to estimate the Galax urceolata ’s size , structure or origin .. " The Green Bank Telescope is a incredibly sore instrument , but its resolution on the sky is reasonably coarse , " O’Neil added . " you may think of it as having ginormous pel in the sky . We make love the target sit down within one of these pixels so now we need to get thick optic images [ and soar in on that pel ] . "

O’Neil desire to do just that using other northerly Hemisphere telescopes such as the Very bombastic Array ( VLA ) in New Mexico or the Large Binocular Telescope ( LBT ) in Arizona . More official document and additional wavelengths should help the squad get deeper images of the galaxy . " If we ’re favourable , we ’ll in reality see the object and then we can originate looking for and appraise other gas pedal , and that will tell us if we ’re correct about the age of the ace in the organisation , " O’Neil said .
Such a gloomy , diffuse and untouched system is right at the extreme point of what we get it on is potential in the universe . For O’Neil , this is what makes the find so exciting .
" My mistrust is that this objective is not alone , " O’Neil said . " It ’s go to facilitate us understand star and galaxy formation as a whole . "
