Asteroid Minerva finds its magical weapons in the sky
Published 12/20/2013 in Franck Marchis Blog Author Franck Marchis
The International Astronomical Union has chosen the names Aegis and Gorgoneion for the two moons of the asteroid (93) Minerva.  My team discovered the small moons in 2009 using the W. M. Keck Telescope and its adaptive optics system. We proposed the names after receiving input from the public. Astronomer J.C. Watson discovered (93) Minerva, a large 150 km diameter asteroid located in the main belt, on Aug. 24, 1867... read more ❯

Fate of Planetary Habitability highlighted at the AGU Fall Meeting
Published 12/11/2013 in Franck Marchis Blog Author Franck Marchis
Together with Cynthia Phillips, one of my SETI Institute colleagues, I will convene a session at the AGU Fall meeting tomorrow afternoon (oral) and Friday December 13 (poster) entitled "Rapid Environmental Change and the Fate of Planetary Habitability". This session will be an opportunity to see recent works on the adaptability of life in abrupt climate crises. Recent discoveries inspire us to re-examine our understanding of how rapidly planetary habitats can be redistributed. Past habitable environments on Mars from the Curiosity rover, possible subsurface lakes on Europa, and potentially habitable exoplanets from the Kepler spacecraft continue to expand our definition of the... read more ❯

How we collaborate with a group of amateur space sleuths to study the triple asteroid (87) Sylvia
Published 10/13/2013 in Franck Marchis Blog Author Franck Marchis
I am back from the 45th annual Division of Planetary Sciences meeting in Denver, Colorado, where I presented my findings on the study of the triple asteroid system (87) Sylvia through a poster and in a press conference (video here). Located in the asteroid main-belt, we know that (87) Sylvia possesses two moons since our publication in Nature Journal in 2005. Our team  has combined observations from professional-class telescopes and from small telescopes used by amateur astronomers to reveal that this 270-km diameter main-belt asteroid has a complex interior, probably linked to the way the multiple system was formed. Artistic... read more ❯

Third day of the 2012 AGU Fall Meeting tomorrow, Wednesday December 5, and I anticipate another busy day. Julie Castillo from Jet Propulsion Laboratory and myself organized a session on the internal structure and composition of small solar system bodies (SSSBs). This session will give us an opportunity to discuss recent results on the compositions and physical properties of asteroids and comets.  The discussion and results should be new since our view on the internal structure of SSSBs has changed drastically over the past decade thanks to the exploration with spacecrafts and the discovery of satellites around several asteroids.
