" Though our rocket program to help commuters to our Moon office is still a long way off, we’ve always jumped at the chance to bring the wonders of outer space a little closer to Earth. On Saturday, our Hubble telescope doodle celebrated 20 years of one of the most productive and celebrated science instruments since Galileo first made a telescopic survey of the heavens 400 years ago.
Hubble's razor-sharp vision has revealed previously hidden aspects of the cosmos with unparalleled intimacy and clarity, and you can see some of the best examples for yourself on our Hubble 20th birthday page. You can also download our new Hubble tour to explore further in Google Earth. And Google Sky Map now includes a Hubble Gallery for you to see Hubble discoveries by pointing your phone to the night sky."
