“However, the triggering mechanism for starbursts and the mechanism of the high mass supply⟳ rate of gas into a galactic center are still unclear.”

“Images like⟳ these will give⟳ astronomers all manner of insight into dust in Andromeda, which in turn⟳ can tell⟳ them the mass of the galaxy, how stars formed (and continue⟳ to form⟳) there, and quite a lot else. That also helps us understand⟳ our own⟳ Milky Way, which, ironically, is hard to study⟳ because of all the dust blocking our view⟳ of the really interesting parts, like⟳ the Galactic center, and dense star-forming regions”

“We appear⟳ to be moving around the Galactic center (which is host⟳ to a super massive black hole) about once every 250 million years.”

“Even though SgrA* is dim right now, we have⟳ clues that it must have⟳ experienced episodes of vigorous feeding in the past. This is not a surprise⟳, given that a gas cloud approaching the Galactic center or a star passing within ten times the horizon scale of SgrA* (which translates to roughly the Earth-Sun separation), would get⟳ spaghettified by the strong gravitational tide there and turn⟳ into a stream of gas that triggers a quasar-like flare.”
