The purpose of this activity is to have you observe the changes in the temperature, absolute magnitude, and other observable characteristics of two different types of stars as they go through their life cycles. The absolute magnitude is a measure of how bright a star would appear if it was approxima ...

Neutrinos interact only very weakly interact with matter, so large detectors are used to record few neutrinos a day. Neutrinos going through a medium (water) ...
