There are over 160 million pieces of human-made space debris, threatening infrastructure critical to life on Earth. But people don’t understand the urgency because debris is not visible. Space Trash Signs — visualizing the consequences of space pollution with the first constellations made from space debris. Millions of moving debris data points were scanned to identify ten new constellations, each representing a different impact of space pollution. Space Trash Signs were brought to life through a web-based virtual observatory and an immersive experience in planetariums and AR stargazing apps.
