made from 3D printed pieces, ‘the wheel of life’ by czechdesigner monika horcicova is a skeletal sculpture that is based on a symbol of infinity. the round structure refers to the repeated cycle of conception and death, with walking legs used to evoke the image of people in motion. the idea explores the fragility of human bones, which despite this are able to carry the weight of the whole human figure during its life. the plaster composite pieces were 3D printed and then placed in a form and casted in a polyurethane resin, the individual pieces were then assembled into a single object.
Is Earth the only living needle in this haystack of planets?
We live in one of a hundred billion of galaxies, each with hundreds of billions of stars. And now, thanks to modern astronomy, we know that the Milky Way is home to perhaps a hundred billion planets! In the past two decades, these exoplanet discoveries have spawned new questions about our universe, and if there might be another Earth, or other life, somewhere out there.
In part one of my two-part series on exoplanets, we’ll look at how astronomers find exoplanets, and what it means to call them Earth-like. We also trace the history of planetary science back three thousand years and examine Earth’s changing status in the cosmos.
We were once the center of the universe, and now Earth is just another rock in the sky. What does that mean for us?
