The galactic recipe for a living planet
Summary
The speaker tells us that for being made a living planet, three ingredients are necessary. It’s the temperate planet, water, and hydrogen cyanide.
There are many planets that are made of only dust and gas, however, we luckily have water and our earth is the temperate planet because we can see chemical reactions or by undergoing chemical reactions, we can be here.
Thus, hydrogen cyanide seems to be needed. It must be the same that bacteria, small microscopic organisms, and fungi are really doing important works on our earth.

And then, by technology growing, by using a new telescope ALMA, the Atacama Large Millimeter and sub millimeters Array in Chile, we seem to know whether a planet releases hydrogen cyanide or not.

From now, we must find a lot of living planets out there. With technology growing, we can know more great things that we’ve never thought.

Words in this story
cyanide /  a salt or ester of hydrocyanic acid, containing the anion CN − or the group —CN. The salts are generally extremely toxic.
