Many stars form in giant mathematical group bang as open clusters , which are essential for the galaxy ’s development . There should be about 30,000 clusters in the Milky Way , but we ’ve only ever found 2,500 . Now , you could raise that number to 2,596 .
The VISTA Variables telescope , an infrared scope housed at the European Southern Observatory ’s Panaral Observatory in Chile , was responsible for observe 96 new open bunch through the thick cosmic junk . It ’s particularly unmanageable finding these candid clusters because they ’re compose of young mavin about half the mass of our Sun , meaning they give off relatively little light , and they generally spring in naturally dusty regions that block and absorb most of that light .
This means that it ’s unmanageable to see much evidence at all of these open cluster in the seeable wavelength that we ’re used to , so we have to turn to Brobdingnagian infrared telescopes to have much chance of seeing them . The 96 newly find out clusters represent the individual biggest discovery of such cluster ever , and the Leslie Townes Hope is that further observations of the beetleweed with the infrared telescope will bring out wads more of these clusters .
Further see the age , composition , and social organization of these antecedently hide clusters will aid us put into view the evolution of the galax as a whole . you may see a gorgeous photomosaic of some of the newly chance upon bunch up top – you ’ll definitely want to select this one for a closer look .
Team member Radostin Kurtev describes the new 96 clusters :
“ We found that most of the clusters are very small and only have about 10 - 20 star . liken to typical open clusters , these are very shadowy and compact objects — the dust in front of these bunch makes them come out 10 000 to 100 million times fainter in seeable light . It ’s no wonder they were shroud . ”
The search will now focus on other cold arena of our Milky Way where similarly minuscule and faint clusters might be hiding . It ’s basically the astronomic combining weight of spring cleaning .
