The research was led by Joshua Emery, an Associate Professor of Astronomy and Planetary Sciences at Northern Arizona University. He was joined by researchers from NASA's Goddard Space Flight Center (GSFC), the Institut d'Astrophysique Spatiale (Universit Paris-Saclay), the Pinhead Institute, the Fl
The case for an icy haze also needs bolstering, says Joshua Emery of the University of Tennessee, Knoxville. But he's intrigued by the second study's proposals for the formation of Ceres and potentially other asteroids. Those scenarios "would be a completely different view of the origin and evolutio

Near-Earth Asteroid 1950 DA Held Together by Negative-gravity Forces
The UT team of researchers, including Ben Rozitis, Eric MacLennan and Joshua Emery, has determined the thermal inertia and density of the asteroid by using thermal images and orbital drift. This method discovered some cohesive forces that are working to keep the asteroids intact. These are known as

UT Research Uncovers Forces that Hold Gravity-Defying Near-Earth Asteroid ...
team found that 1950 DA is spinning so quickly that it defies these forces. Ben Rozitis, a postdoctoral researcher; Eric MacLennan, a doctoral candidate; and Joshua Emery, an assistant professor in the Department of Earth and Planetary Sciences, wanted to know what keeps the body from breaking apart.

Potentially Dangerous Asteroid is Defying the Laws of Gravity
Analyzing thermal images and orbital patterns, Rozitis and his colleagues Eric MacLennan and Joshua Emery theorized that 1950 DA's rotations is so fast it its equator, that it effectively experiences negative gravity.

Asteroid 2005 YU55: what could be gleaned from its close flyby
For astronomers, getting a close look at an asteroid of 2005 YU55's size and type presents a rare opportunity to study a class of objects thought to have contributed organic compounds to a young Earth, according to Joshua Emery, a planetary scientist at the University of Tennessee in Knoxville.
