Our Moon, the Cosmic Ray Detector
The moon provides an easy way to detect rare ultra-high-energy cosmic rays.
To the Center of The Cold Spot
Astronomers measure the randomness in the Cosmic Microwave Background radiation to determine the cause of an anomalously cold spot.
The Echoes of a Supernova
Spectra from the light echoes of distant supernovae can be used to probe the three dimensional structure of these massive and poorly-understood explosions.
