When we look at the sky, we have a flat, two-dimensional view. So how do
astronomers figure the distances of stars and galaxies from Earth? Yuan-Sen
Ting shows us how trigonometric parallaxes, standard candles and more help us
determine the distance of objects several billion light years away from Earth.
Lesson by Yuan-Sen Ting, animation by TED-Ed.

materials that aren't supply-limited and with a lower carbon process? As well
as achieving higher efficiencies at the same time? Perovskite solar panels have
been promising that future for some time now, but where are they? And are they
the future of solar panel technology? Let's explore Perovskite solar panels and
how they might energize our future.

Learn how trees are able to communicate with each other through a vast
root system and symbiotic fungi, called mycorrhizae.
--
Most of the forest lives in the shadow of the giants that make up the
highest canopy. These are the oldest trees, with hundreds of children and
grandchildren. They check in with their neighbors, share food, supplies and
wisdom gained over their lives, all while rooted in place. How do they do this?
Camille Defrenne and Suzanne Simard explore the vast root system and intricate
communication of trees.
Lesson by Camille Defrenne and Suzanne Simard, directed by Avi Ofer.
