In a few thousand years of recorded history, we went from dwelling in caves and mud huts and tee - pees, not understanding the natural world around us, or the broader universe, to being able to travel through space, using reason to ferret out the hidden secrets of how the world works, from physics to chemistry to biology, we worked out the tools and rules underpinning it all, mathematics, and now we can see objects that are almost impossibly small, the very tiniest building blocks of matter, (or at least we can examine them, even if you can't «see» them because you're using something other than your eyes and photons to view them) to the very farthest objects, the
planets circling other,
distant stars, that are in their own way, too small to see from here, like the atoms and parts of atoms themselves,

distant star, a process known as gravitational lensing.

Enough observations would allow an orbit to be calculated, but even two observations should make a
planet more likely than a
distant star if (relative) motion is
detected.
Research in the field of extrasolar
planets is advancing rapidly as new technologies enable the detection of smaller and more
distant planets as well as the characterization of previously
detected planets.
