Astronomical Observing

A critical part of science is engaging minds — young and old. Science is a quest for knowledge that seeks to satisfy our intellectual curiosities. As such, it is crucial that science be open and available for all citizens. If you are interested in touring the night sky, we here at Dartmouth are proud to provide that opportunity.

Every Friday night, while classes are in session, Dartmouth offers a free public observing session — weather permitting. Drop by at any point during the night and view interesting objects with the guidance of a knowledgeable astronomy graduate student. For additional information about public observing, click here or here.

Are you interested in a private, personalized observing session? Do you, or your child, have a science research project that you would like to discuss? Please feel free to contact me if you wish to set up a meeting.

Current Conditions

The Clear Sky Chart above contains information regarding a wide variety of observing conditions. Key for our purposes is the "Cloud Cover" option. Generally, we'd like to see dark blue squares during the time of our scheduled observing sessions, indicating a clear sky! It is one tool we use to decide whether we will be hosting observing on any given night.


While the Clear Sky Chart typically has accurate forecasts, it is only updated twice a day for Hanover, with the last update occurring sometime between 1pm and 3pm. Therefore, it is worth comparing that data with the continuously updated predictions from the National Weather Service. Here, I've embedded their data in graphical form (click to enlarge):



Stellar Forensics

Developed by astronomers at Dartmouth, "Stellar Forensics" is a traveling science exhibit designed to bring the science of astrophysics to the public. The exhibit focuses on reconstructing the death of a star whose life ended with an immense explosion, or supernovae. Using only light, astrophysicists can begin to reconstruct the events that transpired in order to build a detailed picture of the star's death.

The exhibition has received a wonderful reception everywhere it has gone, notably the 2010 USA Science and Engineering Festival (Washington D.C.) and the NH Space Grant 20th Anniversary Exhibition (University of New Hampshire). As a co-developer, I speak on behalf of the whole team when I say that we are enthusiastic about bringing our exhibit to the public. If you have an event and are interested in the "Stellar Forensics" exhibition, feel free to contact me.
