Great casting choice.

Masterlist of all the Bones Comparison pics that I’ve collected! Some of the specific comparisons are ones that others drew my attention too, but a few I stumbled upon myself. All pics are off the ‘net. My apologies for duplicate pics, but I’m not really sorry because I like them all so much.

First up: Thoughtful Bones. Or pensive. Or concerned. Or worried out of his mind. You decide, lol

...I don’t know how to caption this expression, but I do know that I find it amusing.

Soft!Bones! His not-smile! ‘Tis the same! The little crook in it gets me. (My personal favorite)

Top pics: Bones looking at His Idiots(TM) with love. Bottom pics: Bones looking at His Idiots(TM) with pure disgruntled annoyance.

Bones silently questioning your sanity. Or his. Who knows.

No questioning it now, Bones has decided with all of his full Chief Medical Officer Insight that the idiots surrounding him have lost their collective marbles. Now all that’s left to wonder is just where their minds flew the coop to.

Bones Yelling at ALLL the Idiots.

Bones just being himself! ;-)

I might do separate posts containing individual comparisons later. Anyway, I do think that Karl Urban was a spectacular follow up to Deforest Kelley’s portrayal of Bones. They genuinely look like they could be related!

Weird and Wonderful Irregular Galaxies

Spiral and elliptical galaxies seem neatly put together, but what happened to irregular galaxies? Irregular galaxies have one-of-a-kind shapes and many look like blobs! Why do they look the way they do? Astronomers think the uniqueness of these galaxies results from their interactions with other galaxies — like when they pass close to one another or even collide!

Looking back at the early universe with the help of our Hubble Space Telescope’s “deep field” observations, astronomers can peek at galaxies millions and billions of light-years away. They noticed that these far-away galaxies appear unusually messy, showing more star formation and mergers than galaxies closer to the Milky Way.

We also see irregular galaxies closer to home, though. Some may form when two galaxies pass close together in a near-miss. When this happens, their gravity pulls stars out of place in both galaxies, messing up the neat structure they originally had as spiral or elliptical galaxies. Think of it like this: you happen to have a pile of papers sitting at the edge of a table and when someone passes close by the papers become ruffled and may scatter everywhere! Even though the two galaxies never touched, gravity's effects leave them looking smeared or distorted.

Some irregular galaxies result from the collision between two galaxies. And while some of these look like a blob of stars and dust, others form dazzling ring galaxies! Scientists think these may be a product of collisions between small and large galaxies. These collisions cause ripples that disturb both galaxies, throwing dust, gas, and stars outward. When this happens, it pushes out a ring of material, causing gas clouds to collide and spark the birth of new stars. After just a few million years, stars larger than our Sun explode as supernovae, leaving neutron stars and black holes throughout the ring!

Not all galaxy collisions create irregular galaxies — our Milky Way spiral galaxy has gone through many mergers but has stayed intact! And for some interacting galaxies, being an irregular galaxy may just be a phase in their transformation. We’re observing them at a snapshot in time where things are messy, but they may eventually become neat and structured spirals and ellipticals.

Irregular galaxies are similar to each other, but unique and beautiful because of their different interactions, whether they’re just passing another galaxy or taking part in a dramatic collision. Keep up with NASA Universe on Facebook and Twitter where we post regularly about galaxies.
