    Check this out! These are REAL photos, 4K res, from the Moon, looking back at our Earth. 21st century or not, just think about this view. Everyone you know or knew or will know is on that blue planet. And we're all in this one world, together.

    Today (!!) NASA's New Horizons mission crosses the 55 AU mile marker, making it 55x as far from the Sun as Earth. That's almost twice as far as Neptune's orbit, and half a billion miles beyond even the farthest reaches of Pluto's orbit. Go New Horizons!

    TALLY HO ULTIMA THULE!! An ancient relic of solar system formation, 4+ billion miles away, as dark as dirt, & shining only in the faint sunlight of the Kuiper Belt. Here it is, in a New Horizons imaging sequence. SEE IT MOVE, AGAINST THE STARS? TALLY HO! We'll be there on Monday!

    THE STORY IS OUT! I've been selected to be the first ever researcher to fly on a NASA-funded commercial suborbital space mission! See here: swri.org/.../stern-nasa…... Go NASA! Go Science! #DreamDoComeTrue #PersistencePays

    #PI_Daily Less than an hour ago New Horizons crossed the 50 AU marker it was designed to reach. Although four other missions reached this distance back in the 20th Century, none was in perfect health, but New Horizons is. gizmodo.com/new-horizons-c… #Space #NASA #Science 1/

    The LONG hibernation for New Horizons is ending! Yes, tonight we'll take our bird out of its almost 6-month long hibernation and into active ops to begin flyby preps for Ultima Thule at New Years day 2019! GO NEW HORIZONS! #PlutoFlyby
