Gizagizai masu haske da ƙura da ƙura suna haskakawa a cikin wannan hoton Hubble na wani abu na Herbig-Haro wanda aka fi sani da HH 45. Herbig-Haro wani nau'in nebula ne da ba a cika ganinsa ba wanda ke faruwa a lokacin da iskar gas mai zafi da wani tauraro mai haifuwa ke fitarwa ya yi karo da iskar. ƙura a kusa da shi a ɗaruruwan mil a cikin daƙiƙa guda, yana haifar da raƙuman girgiza. A cikin wannan hoton, shuɗi yana nuna iskar oxygen mai ionized (O II) da shunayya yana nuna magnesium ionized (Mg II). Masu bincike sun kasance masu sha'awar waɗannan abubuwan musamman saboda ana iya amfani da su don gano abubuwan firgita da gaban ionization.
Hubble ya zana wani ɗan ƙaramin sashe na Gudun Man Nebula, wanda ke kusa da sanannen Orion Nebula kuma shine abin da masana ilimin taurari suka fi so su gani da hoto. Credit: NASA, ESA, J. Bally (Jami'ar Colorado a Boulder), da DSS; Gudanarwa: Gladys Kober (NASA/Jami'ar Katolika ta Amurka)
Wannan abu yana cikin nebula NGC 1977, wanda shi kansa wani bangare ne na hadadden nebulae guda uku da ake kira The Running Man. NGC 1977 – kamar sahabbansa NGC 1975 da NGC 1973 – nebula ne mai tunani, wanda ke nufin ba ya fitar da haske da kansa, amma yana haskaka haske daga taurarin da ke kusa, kamar hasken titi yana haskaka hazo.
Hubble ya lura da wannan yanki don neman taurarin jiragen sama da faya-fayan faya-fayan duniya a kusa da taurarin matasa, da kuma nazarin yadda muhallinsu ke shafar juyin halittar irin wannan faifai.
