▁between ▁these ▁two ▁super cl ust ers ▁( and ▁to ▁some ▁extent ▁the ▁L ania ke a ▁Super cluster , ▁because ▁the ▁Vir go ▁super cluster ▁is ▁techn ically ▁a ▁part ▁of ▁the ▁much ▁larger ▁L ania ke a ▁super cluster ). ▁ ▁Zone ▁of ▁A void ance ▁ ▁Despite ▁its ▁close ▁proxim ity ▁to ▁Earth , ▁the ▁T aur us ▁Void ▁is ▁a ▁difficult ▁void ▁to ▁study ▁because ▁it ▁lies ▁behind ▁the ▁Zone ▁of ▁A void ance ▁( Z O A )- ▁the ▁area ▁of ▁sky ▁obsc ured ▁by ▁the ▁Mil ky ▁Way . ▁The ▁T aur us ▁Void ▁lies ▁behind ▁an ▁area ▁of ▁high ▁ext inction . ▁ ▁Due ▁to ▁the ▁fact ▁that ▁much ▁of ▁the ▁T aur us ▁Void ▁lies ▁behind ▁an ▁area ▁of ▁high ▁ext inction , ▁scient ists ▁face ▁a ▁challenge ▁when ▁trying ▁to ▁determine ▁the ▁density ▁and ▁dimensions ▁of ▁the ▁T aur us ▁Void . ▁The ▁main ▁problem ▁is ▁that ▁light ▁from ▁dim mer ▁galaxies ▁lying ▁behind ▁the ▁Mil ky ▁Way ▁may ▁be ▁ex ting u ished ▁before ▁it ▁reaches ▁Earth , ▁prevent ing ▁scient ists ▁from ▁obser ving ▁these ▁galaxies . ▁This ▁would ▁lead ▁scient ists ▁to ▁believe ▁that ▁the ▁T aur us ▁Void ▁is ▁em pt ier ▁than ▁it ▁actually ▁is , ▁because ▁they ▁can ▁not ▁observe ▁the ▁galaxies ▁that ▁may ▁be ▁present . ▁ ▁This ▁is ▁not ▁to ▁say ▁that ▁the ▁T aur us ▁Void ▁is ▁not ▁an ▁actual ▁void ▁however . ▁The ▁void ▁has ▁previously ▁been ▁observed ▁in ▁the ▁inf ra red ▁spectrum
