Wendy Freedman

IYA greeting
Wendy Freedman - Carnegie Observatories

I would like to encourage you in this year of 2009, celebrating 400 years of the telescope, to take a moment and get away from city lights, get beyond the cities where many of us have grown up and have never had a chance to look at a dark night sky.

Mountaintop observing
Wendy Freedman - Carnegie Observatories

To obtain the best astronomical observations, it’s desirable to get to high altitude, get away from city lights, find a dry site where the atmosphere is very stable, and the reason for that of course is the clarity of an image that you get is improved if the atmosphere is not in a lot of turbulent motion.

Galaxies and black holes evolve together
Suvi Gezari - John Hopkins University
