For the past 23 years Andrea Ghez, professor of physics and astronomy at UCLA, has been collecting data on stars that orbit black holes. She found that their motion provided an opportunity to test the fundamental laws of physics.
30 years ago, scientist Carl Sagan asked NASA’s Voyager 1 to capture an iconic portrait of our world. This humbling view of Earth from 6.4 billion km away is known as the “Pale Blue Dot.”
