When we suppose of galaxies , we often imagine of bright voluted galaxy full of stars and throttle – but some Galax urceolata have very few stars and look quite dissimilar . These are known aslow - open - brightness beetleweed . They incline to have a lot more dreary subject than unconstipated galaxies like our own , and the normal matter they have is usually in the manakin of gas , with few stars .
astronomer were conducting a survey of 350 of these galaxies using the Green Bank Telescope ( GBT ) , a world - family radio observation tower . when they accidentally spotted an uttermost example of this . J0613 + 52 is located 270 millionlight - yearsaway and it appear to have no superstar . Just a freehanded blob of rotating gasoline .
“ The GBT was accidentally pointed to the wrong coordinate and found this object . It ’s a Galax urceolata made only out of gas — it has no visible star . Starscouldbe there , we just ca n’t see them , ” Karen O’Neil , aged scientist of the Green Bank Observatory , said in astatement .
The team was using multiple telescopes to study the properties of the 350 galaxy when they stumbled on this alone object . Gas is the fuel to make young stars , but it require to be close together for gravitational attraction to take over and maven to be born . This does n’t seem to be happening in the guinea pig of J0613 + 52 .
“ What we do love is that it ’s an incredibly gas racy galaxy . It ’s not demonstrating star formation like we ’d expect , probably because its gas is too diffuse . At the same time , it ’s too far from other wandflower for them to help trigger sensation formation through any brush . J0613 + 52 appear to be both undisturbed and developing . This could be our first discovery of a nearby galax made up of primordial gas , ” added O’Neil .
This galaxy is truly a gripping enigma . researcher believe that it would be important to follow up on this object with deep ocular observation to find the superstar that might survive in this coltsfoot . However , the astronomer feel that it would be important to find more object like this one using wireless observatories .
“ A full sky sight by an highly sore legal document like the Green Bank Telescope could uncover more of these objects , ” O’Neil suggest .
The serendipitous discovery was presented at the243rdmeetingof the American Astronomical Society .
