infinity-imagined:

Exoplanets orbiting stars near the Sun.

Hopefully no one takes this to mean that other stars, and their attendant planets, revolve around us, right? I mean, we’re cool, but we’re not THAT cool.Although the number of confirmed exoplanets is only in the hundreds, the number of estimated exoplanets could be as high as 100 billion (or more?), or one for every star in the Milky Way.And that doesn’t count the cold, presumably dead, rogue planets wandering interstellar space, forever alone.

Early developmental stages of Xenopus laevis embryos. This is a frog commonly used in biological labs, and the favorite amphibian of Nobel Prize winner John Gurdon, whose work on these embryos led to this week’s announcement of human embryonic stem cells made from somatic cell nuclear transfer.
Half a century apart, it’s all connected.

Meet Mr. Camouflage, one of the special stars of sea life in the Lembeh Strait. I literally said “Whaaaaaaaat the f…” when I saw that amazing color change.
Isn’t evolution grand?

17 year Cicada emergence GIF, because I had to see it animate.

The Brood II 17-year cicadas are up and poppin’ along the east coast of the US, according to WNYC’s citizen-science Cicada Tracker map.
Want to know more about these rarely seen prime number nomads? Your humble blogger talked to New Hampshire Public Radio about cicada science. Give it a listen, they say my voice is soothing*

You guys like Saturn, right? Here’s a whole gallery of Saturn GIFs, from rings to moons, captured by the Cassini spacecraft. They’re part modern art and part science.
Next to the Voyager twins, I think Cassini might be the best satellite NASA ever launched. Certainly takes the best pictures. Tumblr’s own staceythinx  has an iPad app called Cassini HD that features even more photos, plus color, plus science.

400.
For the first time in human history, carbon dioxide levels reached an average daily level of 400 parts per million, as reported this week. The last time the atmosphere contained this much carbon dioxide was 3 million years ago.
This new data comes from the Mauna Loa observatory and a set of data continuously collected since 1958: The Keeling curve. This represents almost a 50% increase since the beginning of the industrial age. Although there is some seasonal variability (that little jagged edge) due to seasonal vegetation sucking up a bit of the CO2 every year, the trend is clear … and it’s not good.
So what does that mean? The effects are not something to look forward to. The last time the CO2 level was this high, way back when, here’s what the world was like:

Back then, it was a different world. Global average temperatures during the period were between 5.4 and 7.2 degrees Fahrenheit (3 to 4 degrees Celsius) higher than today, and sea level was as much as 131 feet (40 meters) higher in some places.

While the average (which is calculated from levels over the past several days) has since dropped back to 399 (as of today), the saddest part is that both of those numbers are unacceptable. 400 is just a little more catchy. With 401 and beyond right around the corner, what now? We must cut emissions as fast as humanly possible.
Because we are mighty humans, and it is possible.
We need to take care, because we all share this air. Read about the science of our CO2 contribution here. Watch this episode of It’s Okay To Be Smart to gain some hope maybe.
What do you think is the #1 thing we can do to change? What are YOU willing to do?

Bursting Bubbles
Two UC Berkeley researchers have now described mathematically the successive stages in the complex evolution and disappearance of foamy bubbles (the images above are based off of a computer-generated video that uses their equations).
What purpose does this serve (besides making for some very mesmerizing GIFS…)?  The work has applications in industrial processes for making metal and plastic foams (like those used to cushion bicycle helmets) and in modeling growing cell clusters, which rely on these types of equations.
The problem with describing foams mathematically has been that the evolution of a bubble cluster a few inches across depends on what’s happening in the extremely thin walls of each bubble, which are thinner than a human hair.

Threading the Corona
Top: The magnetic filaments of the sun’s corona, captured at top by Miloslav Druckmüller in a composite of 38 different images during a solar eclipse. You’ll want to see the super-huge version here, trust me. It will change you.
Bottom: “Coronal rain” captured by NASA’s SDO satellite. The superheated coronal plasma is seen traveling along magnetic field lines during a coronal mass ejection. 
The corona cooks at over a million degrees Kelvin compared to the relatively frigid 5800 K of the photosphere below it. Exactly why this plasma is so superheated isn’t completely known, but it might be subject to the same kind of magnetic induction as an electric generator. Whatever the cause, the normally invisible lines of the sun’s magnetic field are drawn in brilliant form within the corona, and charged plasma is the paint.
You can get a good look at the solar corona today (right NOW for those catching this post live at 5:30 PM ET on May 9th) during today’s annular eclipse, being broadcast live from the South Pacific by the Slooh Space Camera.

We never sit here under the weight of all this air, the 5 x 10^18 kg of atmosphere that sits above everyone on Earth, and say “Gosh, that sure is heavy!”
You don’t realize just how powerful that 1 bar (~100 kPa) of pressure is until a train car is filled with steam, allowed to cool, and then implodes ohmygod did that just happen?
For more implosion goodness, check out this awesome video from Veritasium.

From The Old Astronomer (To His Pupil) by Sarah Williams
The full poem:
Reach me down my Tycho Brahé, — I would know him when we meet,When I share my later science, sitting humbly at his feet;He may know the law of all things, yet be ignorant of howWe are working to completion, working on from then to now.Pray remember that I leave you all my theory complete,Lacking only certain data for your adding, as is meet,And remember men will scorn it, ‘tis original and true,And the obloquy of newness may fall bitterly on you.But, my pupil, as my pupil you have learned the worth of scorn,You have laughed with me at pity, we have joyed to be forlorn,What for us are all distractions of men’s fellowship and wiles;What for us the Goddess Pleasure with her meretricious smiles.You may tell that German College that their honor comes too late,But they must not waste repentance on the grizzly savant’s fate.Though my soul may set in darkness, it will rise in perfect light;I have loved the stars too fondly to be fearful of the night.What, my boy, you are not weeping? You should save your eyes for sight;You will need them, mine observer, yet for many another night.I leave none but you, my pupil, unto whom my plans are known.You “have none but me,” you murmur, and I “leave you quite alone”?Well then, kiss me, — since my mother left her blessing on my brow,There has been a something wanting in my nature until now;I can dimly comprehend it, — that I might have been more kind,Might have cherished you more wisely, as the one I leave behind.I “have never failed in kindness”? No, we lived too high for strife,—Calmest coldness was the error which has crept into our life;But your spirit is untainted, I can dedicate you stillTo the service of our science: you will further it? you will!There are certain calculations I should like to make with you,To be sure that your deductions will be logical and true;And remember, “Patience, Patience,” is the watchword of a sage,Not to-day nor yet to-morrow can complete a perfect age.I have sown, like Tycho Brahé, that a greater man may reap;But if none should do my reaping, ‘twill disturb me in my sleepSo be careful and be faithful, though, like me, you leave no name;See, my boy, that nothing turn you to the mere pursuit of fame.I must say Good-bye, my pupil, for I cannot longer speak;Draw the curtain back for Venus, ere my vision grows too weak:It is strange the pearly planet should look red as fiery Mars,—God will mercifully guide me on my way amongst the stars.

From The Old Astronomer (To His Pupil) by Sarah Williams

The full poem:

Reach me down my Tycho Brahé, — I would know him when we meet,
When I share my later science, sitting humbly at his feet;
He may know the law of all things, yet be ignorant of how
We are working to completion, working on from then to now.

Pray remember that I leave you all my theory complete,
Lacking only certain data for your adding, as is meet,
And remember men will scorn it, ‘tis original and true,
And the obloquy of newness may fall bitterly on you.

But, my pupil, as my pupil you have learned the worth of scorn,
You have laughed with me at pity, we have joyed to be forlorn,
What for us are all distractions of men’s fellowship and wiles;
What for us the Goddess Pleasure with her meretricious smiles.

You may tell that German College that their honor comes too late,
But they must not waste repentance on the grizzly savant’s fate.
Though my soul may set in darkness, it will rise in perfect light;
I have loved the stars too fondly to be fearful of the night.

What, my boy, you are not weeping? You should save your eyes for sight;
You will need them, mine observer, yet for many another night.
I leave none but you, my pupil, unto whom my plans are known.
You “have none but me,” you murmur, and I “leave you quite alone”?

Well then, kiss me, — since my mother left her blessing on my brow,
There has been a something wanting in my nature until now;
I can dimly comprehend it, — that I might have been more kind,
Might have cherished you more wisely, as the one I leave behind.

I “have never failed in kindness”? No, we lived too high for strife,—
Calmest coldness was the error which has crept into our life;
But your spirit is untainted, I can dedicate you still
To the service of our science: you will further it? you will!

There are certain calculations I should like to make with you,
To be sure that your deductions will be logical and true;
And remember, “Patience, Patience,” is the watchword of a sage,
Not to-day nor yet to-morrow can complete a perfect age.

I have sown, like Tycho Brahé, that a greater man may reap;
But if none should do my reaping, ‘twill disturb me in my sleep
So be careful and be faithful, though, like me, you leave no name;
See, my boy, that nothing turn you to the mere pursuit of fame.

I must say Good-bye, my pupil, for I cannot longer speak;
Draw the curtain back for Venus, ere my vision grows too weak:
It is strange the pearly planet should look red as fiery Mars,—
God will mercifully guide me on my way amongst the stars.
