It's been an eventful 25 years for what turned out to become the world's best-known telescope and perhaps among the most productive science instruments ever made. Here's a look at Hubble's life in pictures.

Underpinning tributes this week marking the 25th anniversary of the Hubble Space Telescope’s launch is the knowledge that the orbiting observatory has years of cutting edge science projects ahead.
Of all of the dwarf planets we know about, Ceres might be the most mysterious. Recently, scientists found two bright spots on its surface. What could they be?
Mankind seems pretty well set on a 60-second minute. But history saw multiple systems devised for counting things, including the passage of time, so how did we settle on the minutes, seconds, and hours we use to mark off our days today?
