So we look for planets that orbit at just the right distance from their stars.
At this distance, shown in blue on this diagram for stars of different temperatures, planets could be warm enough for water to flow on their surfaces as lakes and oceans where life might reside.
Some astronomers focus their time and energy on finding planets at these distances from their stars.
We don't know what the atmospheres of these planets are like because the planets are so small and dim compared to their stars and so far away from us.
My models show that planets orbiting cooler stars could actually be warmer than planets orbiting hotter stars.
There were no stars and no planets.
Planets form as an incidental process to star formation out of the same gas cloud as the star itself.
Small planets like ours don't have enough gravity to hold on to much hydrogen or helium gas since both of those are very light.
We believe that life arose spontaneously on the Earth, so it must be possible for life to appear on other suitable planets, of which there seem to be a large number in the galaxy.
The expanding supernova shockwave propels its elemental debris through the interstellar medium, triggering a swirling dance of gas and dust that condenses into new stars and planets.
Perhaps one day, we'll see gold rushes to tap the mineral wealth of the other planets of our solar system.
I want to share briefly a tale of two planets.
We couldn't live sustainably on most planets, and we require a lot of resources to stay alive.
There, the self-sufficient machines would land on distant planets.

And so, if we were to dump any of us on Mars right this minute, even given ample food, water, air and a suit, we are likely to experience very unpleasant health problems from the amount of ionizing radiation that bombards the surface of planets like Mars that have little or nonexistent atmosphere.
In our species' struggle to find our place in the universe, we may not always have the time necessary for the natural evolution of extra functions for survival on non-Earth planets.
This was formed over four billion years ago in the earliest days of the solar system while the planets were still forming.
This was once part of a much larger object, one of millions left over after the planets formed.
Newton had given the world a theory of gravity in the late 1600s that works well, describes the motion of planets, the motion of the moon and so forth, the motion of apocryphal of apples falling from trees, hitting people on the head.
They then re-collapsed into another generation of stars and planets.
And on some of those planets, the oxygen, which had been created in that first generation of stars, could fuse with hydrogen to form water, liquid water on the surface.
On at least one, and maybe only one of those planets, primitive life evolved, which evolved over millions of years into things that walked upright and left footprints about three and a half million years ago in the mud flats of Tanzania, and eventually left a footprint on another world.
There are a number of different energy sources available on all planets.
