The African Tulip Trees (Árbol del tulipán) are in full leaf and bloom, adding an explosion of greens and red-orange to the view from Casita Colibrí…


… and providing the colibríes (hummingbirds), who give my apartment its name, a home, playground, and 4-star restaurant.

Colibríes?  I can’t resist!

The Hummingbird Galaxy

I was pondering writing a longish post about the picture above, talking about what galaxies are, how they can physically collide, how their gravity can twist and distort their shapes into all sorts of weird things …

But seriously. That galaxy looks like a hummingbird.* What more do you need?

OK, you need a little more. For one, I’ve written quite a bit about how galaxy collisions happen, so you can read about how these work here and here. The two galaxies in this collision are called NGC 2936 (the blue birdie one) and NGC 2937 (the smaller cottonball one). Together they are known as Arp 142, named for an astronomer who observed weird, distorted galaxy pairs.They’re located about 300 million light-years from Earth.

Two things really stand out to me in this picture (besides a galaxy that looks like a flippin’ hummingbird). One is the long, delicate tendril of dark reddish dust exhumed from the previously spiral-shaped galaxy NGC 2936, flung into a long arc across tens of thousands of light-years of space. I wish we had more three-dimensional data here; I’d love to know what this structure really looks like from different angles. Since dust is very dark, it blocks light coming from behind it, so this tendril is in front of the hummingbird galaxy, or perhaps embedded in it.

The other thing is that the smaller galaxy seems to have survived this collision pretty well. The shape is only mildly distorted; you can see a bit of off-centered nature to the glow of stars around the core. I suspect its more compact nature has a lot to do with that; the stars are closer together, perhaps, and the overall gravity of all those stars helped it retain its shape.

And there is one other thing. These are two very different galaxies colliding! The ex-spiral galaxy is very blue, indicating lots of star formation happened recently. Young, massive stars are blue, and when galaxies collide, the gravitational interaction can cause huge clouds of gas to collapse and furiously form stars.

The other galaxy is yellower, indicating an older, more stable population—blue stars don’t live long, so a galaxy this color must not have formed stars in a long, long time. Billions of years, for sure. You can tell by looking that it doesn’t have much gas and dust in it, which fits; if it had, the collision would have stirred them up, and we’d see more blue stars there as well.

Note too that you can see a handful of far more distant galaxies in the picture. The ones to the lower right are red, which is most likely due to having their light absorbed and reddened by the dust in the hummingbird galaxy; that’s another thing interstellar dust does, much like dust and haze in the air can make a sunset look red.

All in all, there’s a lot going on in this image! The hummingbird shape makes me smile, and don’t get me wrong, it’s cool. But what you’re seeing here is far more than just a shape in the clouds; you are seeing a massive collision on a cosmic scale, the collective might of 100 billion suns, their gravity reaching out and twisting the shapes of these galaxies, stretching them like taffy, molding them like clay.

The Universe operates on the grandest of all scales, manipulating forces and energies far too large for us to grasp in our puny brains. Yet when it does so, it generates beauty and perhaps even amusement in those same brains. It helps us appreciate it and gives us another reason to want to. And, after a while, we really can begin to grasp what the Universe is telling us.

Maybe our brains aren’t so puny after all.

*Some folks say it looks like a penguin. I can see that, but it’s silly. I mean, c’mon, a galaxy shaped like a penguin? Ridiculous.

Wednesday in the Mixteca

cement block building "Fabrica Marmol" "El Colibrí"

How could I resist?  Photo, yes.  Dining, no.  We had already eaten and so were not tempted to try Restaurant El Colibrí, across the street.  However, still scratching my head about the relationship between marble (marmol) and hummingbird (colibrí).

This librarian couldn’t resist doing a little research.  According to Wikipedia, the hummingbird in Aztec culture was, “emblematic for their vigor, energy, and propensity to do work along with their sharp beaks that mimic instruments of weaponry, bloodletting, penetration, and intimacy.”  Hmmm…  the tools and strength needed by a marble mason.  Now, it’s beginning to make sense.

(Thanks Chris for stopping so I could take the above photos.)

And now a song from the Mixteca, “Chikirriyó’i” (“El Colibrí”) (The Hummingbird):

Just before this afternoon’s rains came, Casita Colibrí’s first African tulip tree blossom of the season.Orange red African tulip tree blossom .

And that means, colibríes (hummingbirds) won’t be far behind!

I knew it was going to be a good day when a colibrí greeted me on an early morning stroll up to the weekly organic market.

There were other critters and creatures in plain sight…

A major source of entertainment these gray rainy days is watching the colibríes darting in, around, and through the African tulip trees surrounding my terrace; sipping nectar from the profusion of giant red-orange blossoms 3 times their size;

… chasing each other as they protect their turf (Hey guys and gals, there’s enough for everybody!); catching insects with their rapier like tongues; and pausing for a brief rest at the tip of a branch,

… but always on guard.
