Antarctica is an ideal location to conduct a myriad of astronomical observations,
complementing the space and geophysical observations discussed above. Extremely
cold, dry air and stable atmospheric conditions, together with the ability to observe
objects continuously throughout the long winter or summer, offer unique conditions
for observing our Sun, distant stars, supernova explosions and the cosmic
microwave background. Today, astronomy in Antarctica is thriving, with major
