Interview: Scott Sheppard and his Pluto Fly-By Predictions

Pluto

At its closest approach on 14 July 2015, the New Horizons mission spacecraft will fly by Pluto within about 8000 miles, making it the first spacecraft to visit and photograph the distant dwarf planet.

DTM Astronomer Scott Sheppard is heading a project that is obtaining the deepest and widest survey ever obtained for distant solar system objects. Recent discoveries from the survey range from finding a dwarf planet on the fringe of the solar system to discovering one of the most distant comets to show activity. He took time to discuss this historical visit to Pluto and his predictions for what the new images taken during the fly-by could reveal this week.

Pluto before Pluto

Pluto

With the New Horizons historic flyby of Pluto next week, imagine how excited we were a few weeks ago to unearth a set of plates from 1925 in our vault that include Pluto--five years before Pluto was discovered. This unexpected find led to a bit of historical detective work to uncover the story of these unusual astronomical plates. 

This short video tells the tale of our digging, and what we learned from it, and highlights the amazing work done by astronomers of an earlier, pre-digital era. You never know what you might find in your own archives!

Inaugural Broad Branch Road Poster Gathering

BBR Poster Session

June 26, 2015 marks the inaugural Geophysical Laboratory (GL) and DTM poster gathering at Carnegie's Broad Branch Road (BBR) campus. The event was planned, organized and promoted by the Geophsyical Laboratory's Charles Le Losq, Ileana Perez-Rodriguez and Zachary Geballe. 

The session itself was comprised of 37 original posters from GL and DTM participants; including postdoctoral associates, staff scientists, collaborators from the University of Maryland, alumni and support staff. The Tuve dining hall was buzzing as participants and attendees mingled from poster to poster, discovering all of the different facets of science that are taking place on campus.

Spiral arms cradle baby terrestrial planets

Alan Boss

New work from Carnegie’s Alan Boss offers a potential solution to a longstanding problem in the prevailing theory of how rocky planets formed in our own Solar System, as well as in others. The snag he’s untangling: how dust grains in the matter orbiting a young protostar avoid getting dragged into the star before they accumulate into bodies large enough that their own gravity allows them to rapidly attract enough material to grow into planets.
