There were places in the world commemorating those times when wizards hadn’t been quite as clever as that, and on many of them the grass would never grow again. (2/2) Terry Pratchett.

Any ignorant fool can fail to turn someone else into a frog. You have to be clever to refrain from doing it when you knew how easy it was. (1/2)

@joey_neilsen @drannawatts Yes, indeed!

@ClickToZoom @airandspace @chandraxray The Wikipedia entry has a lot more good stuff - https://t.co/PZg9AjNuiP

[Randall Smith @smith_randallk]

@ClickToZoom @airandspace @chandraxray It’s about 11,000 light years away; the light of the explosion arrived here about 300 years ago (nobody on Earth noticed it, probably because it’s behind a lot of gas and dust and wasn’t all that bright to the naked eye.)

[Randall Smith @smith_randallk]

@airandspace @chandraxray Notice the little dot near the center? That’s the remnant neutron star left over from the explosion. We couldn’t see it until Chandra took this image - it’s wildly hot - millions of degrees - but is only about 20miles in diameter, so hard to see!

[National Air and Space Museum @airandspace]

On this day in 1999, @chandraxray released its "First Light" image of Cassiopeia A. Cas A is the remnant of a star that collapsed about 300 years ago and is 10 light years wide. The X-ray image shows an expanding shell of hot gas from the supernova remnant.

@Delavegalaw @murraywaas You make time for the important things in your life.

[Randall Smith @smith_randallk]

…with good reason….

If Eisenhower came back from the dead, he might say, “You fuckers can’t possibly be Republicans.” And he might follow that up with, “We hanged people like you at Nuremberg.”
