A strong theory has developed that planets form from these disks of material that are leftovers of the star formation process. NASA's Spitzer Space Telescope has detected dust disks around mature, Sun-like stars known to have planets.     
Pakistan Conducts Second Test Of Nuclear-Capable Missile In 10 Days - SpaceDaily  Pakistan on Wednesday test-fired a medium-range ballistic missile capable of carrying a nuclear warhead but insisted it was not sending a signal to India amid continuing peace moves with its regional rival. The Hatf-IV (Shaheen-1) missile, which can hit targets up to 700 kilometers (437 miles) away, was launched from an undisclosed location, a military spokesman told AFP. The test was Pakistan's sixth this year and the second in 10 days. Pakistan and India, who carried out tit-for-tat nuclear detonations in 1998, both conduct regular missile launches. Foreign office spokesman Masood Khan said the test was not meant to send any message to India. The two countries are engaged in a peace dialogue aimed at resolving all issues including the disputed Himalayan state of Kashmir.
