Pluto Grows Under New Horizons’ Watchful Eye

Pluto on May 27 (right) and on June 27 (left). Notice anything different? 


Right now, Pluto is about 25 pixels across in the New Horizons space probe’s long-range camera. In a week it’ll be 50 pixels across. A few days later it’ll be well to 100 … and then it’ll grow by the hour.

What will we see? I wrote about all this for my twice-monthly column for Go see! It’s subscription only, but c’mon. I’m worth it.
