*** Weather Update ***

As of 16:40 on Feb. 7, the weather service is not issuing any warnings for tonight, so the meeting is going to proceed as scheduled. Houston temperature is supposed to be increasing from 37 to 39 between 18:00 and 24:00hrs. While a freeze is not expected, please use caution on overpasses and use you best judgement. Be Safe!

Carbon and nitrogen are two of the elements crucial for life. Originally thought only to come from exploding massive stars, there is now evidence that intermediate mass stars like the sun eject significant amounts of these elements at the end of their lives (via planetary nebulae). Dr. Dufour will talk about these new concepts and a Hubble Space Telescope program to better evaluate the contributions of C & N from stars producing planetary nebulae.
