EDWIN HUBBLE
EDWIN HUBBLE
USA (1889 - 1953)
Edwin Powell Hubble profoundly changed astronomers' understanding of the nature of the universe by demonstrating the existence of other galaxies besides the Milky Way. He also discovered that the degree of redshift observed in light coming from a galaxy increased in proportion to the distance of that galaxy from the Milky Way. This became known as Hubble's law, and would help establish that the universe is expanding.

Astronomy and IYA
Taft E. Armandroff - W. M. Keck Observatory

I think the public is becoming more and more interested in our work. I can see it over my career very easily, never mind over the four hundred years of astronomy.

Advocating more planets
Gibor Basri - University of California, Berkeley

If Pluto is a planet, then several other objects that have been found out in the Kuiper Belt where Pluto orbits which are as big as Pluto, maybe a little bigger, maybe a little smaller, should also be planets.

My science hero: Albert Einstein
Gibor Basri - University of California, Berkeley

My hero in science, like a lot of people is Albert Einstein. I think I just admire the way that he was able to do so much himself working as a single person rather than as a big team and also the way he completely changed our conception of very basic things like space and time.

Brown dwarves
Gibor Basri - University of California, Berkeley

So nature makes stars. We know that. We knew that it made planets in our solar system but we didn’t know for a fact that it made planets any where else, although as I said, we had all of this evidence that it probably did. And then there’s the possibility of making objects that are in between stars and planets. These are called brown dwarves.

What is a planet?
Gibor Basri - University of California, Berkeley

The word "planet" is actually defined in several different arenas which unfortunately don’t have much to do with each other and that’s part of the reason that this is a confusing argument.
