Hubble Deep Field.

Radiolab
Galaxy Quenching

I encountered it in one of those books.

And basically this image, how it was made was they found the darkest part of the sky.

Radiolab
Galaxy Quenching

So as far as we knew, there was nothing there.

And some astronomers said, why don't we point the Hubble Space Telescope at this dark patch of sky for 10 days, which was a very kind of bold and crazy move because Hubble Space Telescope time is very precious and expensive.

And some people thought nothing would be there.

Radiolab

Like, why point it in complete darkness?

Radiolab
Galaxy Quenching

And yeah, they used Hubble to stare at this dark place in the sky for 10 whole days.

Radiolab

And then the image that came back had thousands of galaxies in it.

Radiolab

If it's very bright and has those spikes around it, it's a star with, you know, a star in between us and those galaxies.

Radiolab

But everything else is an entire galaxy.

Radiolab
Galaxy Quenching

There's some red orb galaxies in there.

Radiolab
Galaxy Quenching

Oh, are they like these orangey ones?

Radiolab
Galaxy Quenching

Yeah, they're really red.

Radiolab
Galaxy Quenching

We call them quiescent galaxies when they're red and dead like that.

Radiolab
Galaxy Quenching

Right, exactly.
