Seyfert's Sextet
Image Credit: Hubble Legacy Archive, NASA, ESA; Processing: Judy Schmidt

What will survive this battle of the galaxies? Known as Seyfert's Sextet, this intriguing group of galaxies lies in the head portion of the split constellation of the Snake (Serpens). The sextet actually contains only four interacting galaxies, though. Near the center of this Hubble Space Telescope picture, the small face-on spiral galaxy lies in the distant background and appears only by chance aligned with the main group. Also, the prominent condensation on the upper left is likely not a separate galaxy at all, but a tidal tail of stars flung out by the galaxies' gravitational interactions. About 190 million light-years away, the interacting galaxies are tightly packed into a region around 100,000 light-years across, comparable to the size of our own Milky Way galaxy, making this one of the densest known galaxy groups. Bound by gravity, the close-knit group may coalesce into a single large galaxy over the next few billion years.

It's time to play "Apply What You Just Learned!"

This is Stephan's Quintet. Only four of these five galaxies are interacting. Based on what you just learned about Seyfert's Sextet, can you tell which one is not gravitationally bound to the others?

I want to say the four on the left as they are closets together, but the lower left looks undeformed.
Is it the odd man out?

The undeformed, non-mutant, blue spiral galaxy (NGC 7320) is indeed the odd man out in that group! Good job. Accolades for you.
In fact, it is REALLY out. It's a full 260 million light years closer to our galaxy than the other 4 interacting galaxies.
Thanks for playing "Apply What You Just Learned!"

Ooo, I wonder what the view looks like on one of the habitable planets there.

I can't say for sure, but here's an artist's rendering of what the night sky will look like when Andromeda collides with the Milky Way in about 4 billion years.

I know I sound like a faggot, but sometimes I like to imagine myself in between two of those galaxies in intergalactic space, completely all alone, just waiting for nothing . Must be really lonely out there

Not that there will be an Earth by then what with sun bloat.

Whatever is living on Earth will have about a billion years to enjoy that sight. The Sun isn't expected to become a red giant for 5-6 billion years.
