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 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.

Oct 28 Recap
Today's host was Jesse Rogerson.
1. Ares I-X, NASA's next generation spacecraft and launch vehicle system has taken its first flight test today successfully. Read NASA's news release here.
2. Which method is more efficient to detect the first galaxies (z:6~12), lensing or blank fields? Based on the simulations they are both needed. Read the journal paper here.
