The analysis of the youngest pair of identical twin stars yet discovered has revealed surprising differences in brightness, surface temperature and possibly even in size, suggesting that the stars formed at significantly different times rather than simultaneously as generally assumed.
Black Holes Have Simple Feeding Habits

The biggest black holes may feed just like the smallest ones, according to data from NASA's Chandra X-ray Observatory and ground-based telescopes. This discovery supports the implication of Einstein's relativity theory that black holes of all sizes have similar properties, and will be useful for predicting the properties of a conjectured new class of black holes.

Transistors based on a new kind of material created by Northwestern University researchers have been lifted into outer space on the space shuttle Endeavour and attached to the outside of the International Space Station for radiation testing. The transistors, which used a new kind of gate dielectric material called a self-assembled nanodielectric, will remain there for a year as part of a NASA materials experiment to see how they and other materials hold up to the harsh space environment.

Conditions on the moon will be harsher, but prototype NASA robotic vehicles braved sand storms and unprecedented temperature swings this month on sand dunes near Moses Lake, Wash., to prepare for future lunar expeditions. Teams from seven NASA centers and several universities conducted the tests from June 2-13.

Quotes:
The courage to be is the courage to accept oneself, in spite of being unacceptable.
War may sometimes be a necessary evil. But no matter how necessary, it is always an evil, never a good. We will not learn how to live together in peace by killing each other's children.
If you must love your neighbor as yourself, it is at least as fair to love yourself as your neighbor.
