This week's journal club was led by Prof. Pat Hall. Some highlights are
1. Gamma-ray telescopes show origins of cosmic rays. Fermi's first year observation shows evidence of the connection between SNe remnants and the acceleration of CR hadrons. Read the article here.
2. HARPS search for extra-solar planets around dwarf star GJ876, the radial velocity measurements indicate an Earth-mass size planet or smaller. Read the paper here.

Recap: Jan 13, 2010
The first astronomy journal club of this year was hosted by Alireza Rafiee. Some highlights are following:
1. A complex form of mathematical symmetry (E8) linked to string theory has been spot first time in laboratory experiments on exotic crystals. Read more here.
2. Kepler mission news: five new planets have been identified just using the first six week's science data. Read it here. Want to know the science of Kepler mission visit here.

Dec 2 Recap
This week's host is Prof. Paul Delaney.
1. LHC officially becomes the most powerful accelerator. Both proton beams were powered to 1.18 TeV, the speed of the protons are 0.9997 times the speed of light. Read the story here.,
2. Report from Cassini mission: the eccentricity of Saturn's orbit around the sun may be responsible for the unusually uneven distribution of lakes over the northern and southern polar regions of Titan. Read more here.

Nov 25 Recap
This week's host is Sunne Dong. Few things we talked about:
1. Rings of stars found in the giant elliptical galaxy Centaurus A, results of "a violent event" of merging galaxies. Read the story here.
2. Looking cosmic rays in starburst galaxies, read the papers here and here.
3. A nova, V445, might become a SNa I in the future. Read more 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.

Nov 11 Recap
Today's host was Alireza Rafiee.
1. NASA plans to launch Atlantis on November 16 for an 11-day flight to the International Space Station. Read the mission's details here.
2. Many observations have been planed this week around Rosetta's Earth swing-by. Read more here.
3. An unusual rapid supernova SN 2002bj, originally identified as a Type II supernova 7 years ago, has been rediscovered as a new type of exploding star. The explosion is believed to be caused by helium flows from one white dwarf onto another in a binary star system. Read here.
4. How many universes are there? String theory says 10 to the power of 500, quantum fluctuations produce 10 to the power of 10 to the power of 10 million. But does it really matter in a world ruled by quantum physics, where an observer's brain can only tell 10 to the power of 10 to the power 16 universes apart? Read more here.
