It is the spectrum of a planet like Earth, showing a presence of nitrogen dioxide, as a clear signal of life, and oxygen and ozone.

Now, there was no carbon and oxygen in the universe at the Big Bang.

Decide which instruments, stock it up with consumables.

My next step's gotta be oxygen.

What's a drug?

There are three basic limitations of scuba diving.

This isn't Volvos this is volcanoes.

Now that's an incredible phenomena, because it's a star that sits there.

That's what we use to inject, as we start to do our deep dives.

We need to breathe.

These granules contain three essential plant nutrients.

This was a different record.

Carbon dioxide, having never gone above 300 parts per million, here is where CO2 is now.

Meanwhile, the human body consists of 65 oxygen, 18 carbon, 10 hydrogen, and 7 of various other elements including 0.002 of silicon.

We stopped tilling, so that we could prevent greenhouse gasses from going into the air.

It appeared dead.

High oxygen content.

Oxygen! Yes!

Pure oxygen.

Oxygen, yes. Thermal garments...

What's the O2 stat?

Give me an O2 stat.

Iron and oxygen are elements.

Water contains hydrogen and oxygen.

Liquid hydrogen and oxygen.

Hm.

Trees give off oxygen and absorb carbon dioxide.

What an amazing house you have.

Tropical rainforests produce oxygen and consume carbon dioxide.

And then you have two extra pairs of valence electrons in the oxygen.

Nitrogen bonds to oxygen, which in turn....

And after the toe cells have kind of taken out whatever they need.

I'm H2O intolerant.

You need oxygen to breathe.

And there was no carbon and oxygen in the universe throughout the first generation of stars.

I wonder if he's at home.

So let me just say population.

Oxygen and hydrogen make water.

They've discovered a new bond, a new material for transparent solar cells.

It's here, the brain.

(Laughter) (Applause)

How you doin' on air?

Doctor, the patient is desatting.

O2 sat's down 82 percent.

Danger. Atmosphere compromised.
