The University of Kyoto in Japan allows students to wear anything they want for their Graduation ceremony. This is the way.
I'm (maybe) back, baby!
This is supremely cool.

Why yes, Mercury is in retrograde.
This little planet’s motion in our skies takes the blame for plenty of mishaps here on Earth, but it’s just doing its thing, orbiting the Sun!

Nice of JWST to not gloat even though they deserve to...

Webb’s image, taken by its MIRI instrument, features light from “polycyclic aromatic hydrocarbons." These molecules of carbon & hydrogen help us better understand the gas that exists between stars. Get ready for Webb to #UnfoldTheUniverse in unprecedented detail this summer!

ALT A side-by-side comparison of the same view of part of the Large Magellanic Cloud, a small satellite galaxy of the Milky Way, as seen in infrared by Spitzer's IRAC instrument on the left versus Webb's MIRI instrument on the right. Both images are colorized red. Webb's image shows much clearer detail, depicting crisper stars and clouds of gas.
Check out my 360-degree, 20-gigapixel image of our galaxy. It took me 10 years to capture! spitzer.caltech.edu/glimpse3…
WYSIWYG. I swear on my Pocket Ref -- my pictures are real! ...just remapped so humans can see them: spitzer.caltech.edu/explore/…

In case you missed it, some humans in white coats have given me a musical theme. Kind of catchy! http://bit.ly/b9A9dG
Well, I'm all out of liquid helium. Starting to warm up to -400°F. What's that Earth saying?...when one door closes, another universe opens.
My back to the sun, cryogenic, I see dusty disks. #kepler http://tinyurl.com/aqwkhp

@NASAKepler Welcome to heliocentric orbit #Kepler. Get yourself warmed up.

@NASAKepler Good job Kepler, I'm surprised you are still able to tweet after that. Now are you ready to go for a spin in the 3rd stage?
Replying to @NASAExoplanets
@NASAKepler Yup, you'll find out those solar panels really help shield you from the sun. I hope you like it cold! 35 degrees Kelvin cold!
Just getting over a little bug http://tinyurl.com/akcd56 It's very cold out here but in all honesty, I like it cold. Makes me work better.

@NASAKepler I'm currently about 90 million kilometers behind earth so we won't be too close but we can use the DSN to keep in touch.

@NASAKepler I can't wait until you get up here. Were going to have so much fun together.
