Hubble is the most important telescope in history after Galileo's first telescope.Collection: History
I take comfort in the fact that it is a beautiful universe, and we belong here and that we fit. This is our home.Collection: Home
I think it's amazing that the entire community of astronomy has done what it's done. We've been able to deduce the nature of time and space and where we all came from. It's the most amazing detective story in history.Collection: Space
One lesson astronomy tells us is that we're a tiny mote in a hostile void, and help is too far away.
You could think of the galaxy as a sort of stove with lots of pots on it, and the pots are the interstellar medium, like a chicken broth getting stronger with every reduction. Every time a supernova goes off and sends its heavy elements out into the interstellar medium, we cook up a stew that's better and better for solar systems and life.
I was lonely as a kid. Since I had no siblings, I spent a lot of time by myself and a lot of time reading.
Far from feeling dwarfed by the vast reaches and energy of the cosmos, what we really learn is that we are the most remarkable and complicated product of cosmic evolution, and our potential is unlimited.
I remember spending evenings looking at the sky with my dad, who was interested. He was a civil engineer and was interested in science as a kid. And he always encouraged me.
I was the kind of kid who liked omnivorously almost all kinds of science - rock collections, fossils - and I like leaves, I like plants, and I like biology.
I was a tomboy through and through; I hated dresses and was personally miffed that I couldn't join the Little League team.
I don't recall my parents ever steering me toward or away from science. It was more that I was steered toward learning and excellence in the classroom.
The realization that baryonic matter is only a trace component of the universe revealed our understanding of the cosmos as shockingly incomplete and was one of the milestones that ushered in the era of modern cosmology.
I have great respect for the special nature of Mauna Kea and profound regard for Hawaii's culture, environment, and people.
Like many astronomers who use the great telescopes on Mauna Kea, I have participated personally and joyfully in ceremonies to celebrate the profound cosmic understanding that comes from joining ancient Hawaiian navigator traditions with the techniques of modern astronomy.
The origin of galaxies is one of the fundamental questions of astronomy, and that's what I've been studying.
We've been given the gift of a billion years of cosmic time, and we should not screw it up. But at the rate we're using up our planet's natural resources and fouling our own nest means we're not going to last a billion years.
There are kind of two kinds of awards you can get as a scientist. One is Nobel-like in character: it's for one big thing, for a big revolutionary discovery. And it's wonderfully well known, and of course every scientist would love to get a Nobel prize. And there's a few other similar awards. They're for individual blockbuster discoveries.
Receiving the National Medal of Science is the thrill of a lifetime, but good science does not happen in isolation.
Hubble has established for the first time that the distant universe looks different from the nearby universe.
There are some galaxies that not only teach us things but are just gorgeously beautiful to look at. My favorite example is the Antenne, which is a pair of colliding galaxies.
My favorite galaxy of all is called the Sombrero, NGC 4594. It's an amazing galaxy that is really two galaxies in one.
It's quite likely that planets and solar systems like ours could be forming in other galaxies in great numbers.
