Leonard David's INSIDE OUTER SPACE

U.S. President Obama’s Chief Science Advisor — Dr. John P. Holdren — sent out a note earlier this week from the Office of Science and Technology Policy (OSTP).

“Here’s what I passed along internally Monday morning,” Holdren wrote.

“Today’s morning report from NASA contains a Hubble photo I thought worth sharing,” Holdren noted. “The astonishing density of stars — most of which, we now know, have planets — really does make one wonder whether there’s anybody else out there. And this is just one piece of our own galaxy. There are an estimated 100 billion other galaxies in the observable universe. Enjoy!”

“P.S. — The President liked this photo so much, he tweeted about it!,” Holdren added.
