The Hubble Space Telescope has been taking high-resolution images of the universe for 25 years now. Daniel Clery of Science magazine reflects on Hubble’s many discoveries.

DANIEL CLERY (Science Magazine):

It can detect some of the very first galaxies from the early universe; so it’s the first time we’ve been able to see what they look like. And it’s demonstrated that most galaxies out there have a supermassive black hole at their heart, so that’s something we didn’t know before.


The telescope has also led to a better understanding of the age of our universe and the rate at which it is expanding. And, it took the first snapshots of an exoplanet.


You always find things you’re not expecting, and that’s been one of the joys of Hubble, it’s discovered things that weren’t even dreamt of when it was built.
