The inexorable subduction of the pacific plate regularly brings earthquakes to Japan. We often pause briefly to admire the readiness and civil defense response that shows their preparation and courage to deal with such events.
Today the world stops to catch its breath and stand with Japan in the face of this monster earthquake and tsunami. It brings the realization to all of us, the tenuous hold we have on life, on this our "third rock from the sun".
Plate tectonics allow life to exist, brings us our rich volcanic soils, and yet can take life with such savagery that stuns us, and causes us to ponder.
To the people of Japan, and all our friends in the astronomy community in Japan -
Welcome to this week's Carnival of Space #188.
I am constantly amazed that up to 60-90% of traffic to my own blog comes from mobile devices, in the spirit of that, today I will provide a QR Scan code to each of the Home Pages of our intrepid bloggers. Download your preferred QR Scan code app from your handheld device provider and away you go.
So here we go its Carnival Time!!!!
In keeping with the reflective tone, Steve Tilford's personal tribute on the passing of his friend and mentor Dr Jim Elliot, covers his life, his philosophy and great discoveries (eg. he was on the team that discovered the rings of Uranus). Steve's detailed coverage has collected some thoughts and reflections from other scientists about the legacy Dr Jim has left us all. Read it, and ask yourself the question - what legacy will I leave?

Vega 0.0 also takes some time to reflect - on pioneer astronomer Friedrich Wilhelm August Argelander's work and covers "método Argelander"(Argelander method) for observing variable stars. This article is in Spanish, which gives you a second reason to try out online translation tools this week.

Chandra Blog this week features a stunning image of NGC 4151, a spiral galaxy with an actively growing supermassive black hole at its center. The structure has been dubbed "The Eye of Sauron" by astronomers due to its resemblance to the character in "The Lord of the Rings" movies. The image is a composite of X-ray, Ha and Radio spectrum. Read the amazing story of how this image was compiled.

Next Big Future reports this week on Russia's plans for a megawatt nuclear space reactor and using it for space tugs and Mars missions. Brian continues the "powering up" theme with VASIMR's plans for the next 5-10 years and getting up to 1-6 megawatt missions.
Sounds like they'll have enough power budget for blutooth .......everything is better with Blu......(yes, yes we know)[Bigbang Theory].
Brian also updates us on details of the minimag Orion for near term interstellar missions. The full paper is available for free online.

AstroBlogger reports on the post paper forensics of claims that fossil bacteria have been found in a meteorite. It's just magnesium sulfate nanobelts folks.

TheSpacewriter continues on the meteorite story and takes on the journalistic ethics of those who ran with the meteorite-life story last week and didn't bother to check the facts. Carolyn is much more qualified than I am to say what you can and can't do in 72 point font.

At Cheap Astronomy, Steve takes us to places far, far away and talks in one of his well respected podcasts about about dwarf galaxies - large and small.

At WeirdWarp, Chris tries to lift the self esteem of asteroids by suggesting more useful things for them to do than killing dinosaurs. Arriving on an asteroid second after someones been there for a fit-out seems perfectly logical. Think big people!
Maybe we CAN send the telephone sanitizers first. [Hitchhiker's Guide to the Galaxy].

Now you might think that Asteroids have a self esteem problem, but what about Ceres. Astropixie puts Ceres "on the couch" for a session on why Pluto had it coming!! [Warning: contains astronomy terms that might not be suitable for astronomers young enough to not know what a ...hmm ..."two body problem" is"].

As opposed to being demoted, what if you never made it in the first place? A brown dwarf, about 75 light-years from Earth, has hit a new low. In fact, its temperature is so low that it is about the same temperature as the cup of tea sitting on Ian's desk. Discovery News asks the question: Stellar-Failure or just misunderstood?

Nancy, Senior editor of Universe Today features an article on the Catalin Fus image of STS-133 mission to the ISS passing infront of the sun past the currently active sunspot region.

So, as we bring the Carnival of Space 188 to a conclusion, mindful of the powerful forces at work on our planet, in our galaxies, and yes even in our failed stars, lets use this time of confronting disaster for personal relfection on the legacies that have been left by others and the ones we might leave.
I leave you with a lovely image of M106 taken by John Nunn this week on my telescope.
