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.

3. Meteorite found by the camera network. The Desert Fireball Network monitors the Nullarbor desert in Western Australia and tracks meteorites. Read the story here.

4. arXiv:0911.2530v1 high star formation activity even found at a distant cluster (z=1.46) center.
