Reflective Self-Assembling Proteins

Prof. Alison Sweeney studies the biophysical properties of reflectin - a highly reflective and self-organizing squid protein found in cephalopods like the Hawaiian Bobtail squid shown here.


Euclid Mission to Explore Dark Energy

Euclid is an ESA mission to map the geometry of the dark Universe. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures.  Penn researchers are part of the Euclid science team.


Atacama Cosmology Telescope - in the north of Chile

The Atacama Cosmology Telescope (ACT) is a 6-meter telescope located in the Atacama Desert of Chile on Cerro Toco.  It's goals are to study how the universe began and evolved to its current state and to discover its major constituents.  By observing the cosmic microwave background with great precision, the ACT experiment should get unprecedented measurments of cosmological parameters.

High-Bay Space at DRL

This cube-shaped building sits just east of DRL.  The high-bay provides faculty and students a facility for research, fabrication, and telescope display.  The building has a 42 foot high ceiling, exposed structural steel framing, and a crane beam and glass sliding doors for moving large telescopes in and out.  It was completed in January 2012.
