Hubblecast 20 Special: Technology to the rescue

Progress in telescopic astronomy would have come to a grinding halt in the second half of the twentieth century if it weren?t for the digital revolution. Powerful computers have enabled a wealth of new technologies that have resulted in the construction of giant telescopes, perched on high mountaintops with monolithic or segmented mirrors as large as swimming pools. Astronomers have even devised clever ways of undoing the distorting effects of atmospheric turbulence and of combining individual telescope mirrors into virtual behemoths with unsurpassed eyesight. The optical wizardry of 21st century telescope building has ushered in a completely new era of ground-based astronomical discovery.

I love these videos too - it's amazing that they have such a positive effect on people's mood, don't you think?!! :> This particular video really explained a great deal about the new telescope technology! Sir Isaac Newton must be very pleased at how far the science of optics has come!!!! Thank you all involved in this!
