Small Galaxy Punches Hole In Andromeda
space.com ^ | 10/17/05 | Ker Then

Posted on 10/17/2005 7:06:43 PM PDT by KevinDavis

Sometime in the distant past, the dwarf galaxy M32 hurled itself at its much larger neighbor Andromeda, delivering an explosive uppercut punch that left a jagged hole nearly 10,000 light-years across in Andromeda's plane of stars, one that millions of years later has yet to fully heal.

New infrared images from NASA's Spitzer Space Telescope recently revealed the hole, which is hidden to optical telescopes behind Andromeda's veils of cosmic dust and gas.

The Spitzer images also revealed other features of Andromeda that have never been seen before, including bright, new stars and spiral arcs swirling out from the galaxy's center.

I'm pretty sure Andromeda and the Milky Way are supposed to collide as some point in the future. Far in the future.

By the way, who named the Milky Way? Really, what kinda name is that? Andromeda sounds much cooler. =P

" By the way, who named the Milky Way?"

I hear M&M / Mars bought the naming rights for our galaxy about 100 years ago...

In fact, Andromeda will collide with our own Milky Way Galaxy in about 3 billion years.

So we don't have to worry about the sun going nova in 5 billion years? Hmmmm.

Something don't compute right here.

Galaxias Kyklos -- Milky Circle

Via Lactea -- Milky Way

The names are old.

Maybe they should rename M32 "Gorgon"

Where is FEMA when you need them? Maybe Bush could send some troops there to make himself feel better, Im positive
hes the only one in our galaxy who gives a rats rear end.
If it were up to me Id tell every stinking galaxy you are on your own, and dont try sending any kruddy guest workers here either!

It might be best for you to think of a galaxy as a gas that has no internal pressure that is held together by gravity. When another gas of the same type tries to pass through, it is not necessarily going to cause collisions (because that would imply that either gas had an internal pressure). It will, however, alter the gravitational forces that control these galaxies. Stars will move in different paths, and in certain areas the density of the stars will increase or decrease. It is unlikely that our Sun will be physically battered. It will more likely follow a slightly different path each time it orbits our galaxy. Since it is estimated that our Sun takes about 250 million years to complete an orbit, and this galactic collision which will occur in about 3 billion years will probably take about a billion years from beginning to end, the big question is where our Sun will end up once it is done. Will we be citizens of the Milky Way Galaxy? Will we have a lot more or a lot less stars nearby?

Milky Way is just the translation of Galaxias, which is what the Greeks called it. If Andromeda were similarly translated, then it'd be the Ruler of Men (which is still much cooler..)

I like the Chinese or Japanese myself: Silver River (yín hé) or Heavenly River (Amanogawa).

Galaxias kuklos = Milky circle, used of course just as we use Milky Way, as a reference to the appearance in the sky. Aristotle discusses its nature and concludes it is a sort of cosmic dust accumulated in one spot by the gyrations of the heavens.

Even as late as 1900 "the Galaxy" was a synonym for "the Milky Way" although it did seem to refer to the object itself rather than the appearance. At that time, there was speculation that some nebulae might be "external galaxies" or "external universes", although conservative opinion was against it.

So "the Milky way galaxy" is formally redundant. It's a similar situation to calling "our sun" "Sol", which of course just means sun.

This is silly, naming a galaxy "The Milky Way." I think Baby Ruth, Payday, Abba Zabba, or Almond Joy is much better.
