core

Wannan bangare na Milky Way aka located a cikin ƙungiyar taurari Sagittarius. A core ne tushen wadanda ba thermal radiation, da ciwon game da miliyan goma digiri zazzabi. A tsakiyar wannan ɓangare na Milky Way ne hatimi, kira "kumbura". Yana da wani dukan kirtani na haihuwa taurari, wanda motsa a cikin wani elongated falaki.

Forecast nan gaba

Masana kimiyya bayar da shawarar cewa a nan gaba sosai m karo tsakanin Milky Way da sauran taurari, da most of wanda shine Andromeda Galaxy. Amma a lokaci guda zuwa ga magana musamman game da wani abu shi ne, ba zai yiwu.
