2. Looking cosmic rays in starburst galaxies, read the papers here and here.

Nov 18 Recap
This week's astronomy journal club was hosted by Prof. Pat Hall. Something we discussed about were:
1. The LCROSS team announced the mission successfully uncovered water during the Oct. 9, 2009 impacts near the moon's south pole. Read more here.
2. On Nov. 6, an asteroid, 2009 VA, came only about 2 Earth radii from impacting the Earth. It is the third-closed known non-impacting asteroid, only noticed by astronomers 15 hours before its closest approach. Read about it here.
