Earth Minutes to Hours Years to Thousands of Years Millions to Billions of Years Billions of Years Time it takes light to reach Earth
The light Hubble sees today may have taken thousands, millions, even billions of years to reach us, carrying the story of events that happened in the distant past. Click on the pictures at the top of this page to see how far we are looking back through time.
From Mars, light takes just a few minutes to reach Hubble. From Jupiter, a little over half an hour. From Saturn, a bit more than an hour. From Pluto, about 5 hours. Hubble can observe dramatic changes on the planets and their moons on the same day they occur.
