Discovery of Activity at Asteroid 2016 BA14
Feb 2016: The orbit of asteroid 2016 BA14 has been shown to be remarkably similar to that of comet 252P/LINEAR 12. With both objects headed for close approaches to the Earth in March 2016, we decided to look closely at asteroid BA14, and guess what we found: a comet's tail!
The Spitzer Space Telescope and a Survey of Cometary Activity
January 2015: With the Spitzer Space Telescope, we can survey how much carbon dioxide comets produce through their orbits, and assess its role in comet activity.
