Тайлбар: Messier 101 (M101) хэмээх энэ асар том мушгиа одны ордыг сансрын олон дахин ашиглагдах Endeavour хөлгийн Астро-2 аяллын үед (1995 оны гурван сарын 2-18) хэт ягаан туяаны телескопынх нь тусламжтайгаар авчээ. Уг зургийг компьютерээр боловсруулсан тул одоо өнгүүд нь хэт ягаан туяаны хүчийг харуулж байна. Одны ордны ийм зургууд нь хэт ягаан туяанд тод харагддаг, нарнаас олон дахин том, шинэ оддын үүлийг харуулдаг. Харин үзэгдэх гэрлийн зурганд хөгшин оддын шар, улаан өнгө голлодог. Хэт ягаан туяа нь нүдэнд харагддаггүй ба атмосфер дахь озоны давхаргад шүүгддэг тул тэнгэрийн биетийн зургийг сансраас авдаг.
Explanation: This giant spiral galaxy, Messier 101 (M101), was photographed by the Ultraviolet Imaging Telescope onboard the Space Shuttle Endeavour during the Astro-2 mission (March 2 - 18, 1995). The image has been computer processed so that the colors represent the intensity of ultraviolet light. Pictures of galaxies like this one show mainly clouds of gas containing newly formed stars many times more massive than the sun, which glow strongly in ultraviolet light. In contrast, visible light pictures of galaxies tend to be dominated by the yellow and red light of older stars. Ultraviolet light, invisible to the human eye, is blocked by ozone in the atmosphere so ultraviolet pictures of celestial objects must be taken from space.
