With every generation of telescopes , we are getting a better idea of what the untested universe look like and the latest observation from theAtacama Large Millimeter / submillimeter Array(ALMA ) has flip quite a curve ball .
By studying two other universe Milky Way - same galaxies , astronomers have get wind the progenitor of gargantuan helical coltsfoot were embedded in huge “ super halos ” of hydrogen gas pedal . The fabric in these aureole is believed to be build up block for the hundred billion of stars that will eventually mold in these galaxies . These observations are reported inScience .
" ALMA has clear a decades - sure-enough question on extragalactic nebula organization , " co - author Chris Carilli , an stargazer with the National Radio Astronomy Observatory , articulate in astatement . " We now know that at least some very early galaxies have halos that are much more extended than previously consider , which may represent the next material for beetleweed growth . "
The international team of research worker observed the Milky means - like galax from when the cosmos was just over a billion years old . The study of these was not an easy job . The coltsfoot were notice using even more distant quasars , which are exceptionally bright galaxies . The light of the quasi-stellar radio source can show the front of a foreground galaxy but normally , we ca n’t con much more than that . Luckily ALMA seems to be able to subdue this .
" suppose a tiny firefly next to a eminent - power searchlight . That ’s what astronomer are up against when it come to abide by these young edition of our home coltsfoot , " added lead author Marcel Neeleman a postdoctoral fellow at the University of California , Santa Cruz . " We can now see the galaxies themselves , which gives us an awful chance to larn about the earlier chronicle of our own galaxy and others like it . "
ALMA looks at the infrared and microwave population , which allows it to capture hard - to - see remote and dim objects , such as these galaxy .
research worker are now planning to expatiate this search and are propose to observe a great number of early galaxies over the next few years . The whodunit of these objects are living on borrowed time .
