Watch as the most powerful space telescope ever built drifts ever farther from Earth.
Masi's video shows Webb in space, on its way to its final destination, a gravitationally stable point in space called L2, or the Earth-sun Lagrange point 2, about 1 million miles from Earth.
At the time, the observatory was about 340,000 miles from Earth, Masi wrote. That's about 100,000 miles beyond the moon's orbit.
