You’ve probably heard about space debris and the growing risk of collision to satellites and space stations. According to Moriba Jah, who created ASTRIAGraph at the University of Texas at Austin, there are 26,000 trackable objects in space (excluding the smallest), of which only around 4,000 are currently working. Moriba collects information on orbiting objects by aggregating information from different countries, companies, other scientific researchers, amateur telescope astronomers, and more. The resulting graph identifies individual objects and their distances from each other.

KNOWLEDGE GRAPH: Solving Wicked Space Problems With ASTRIAGraphMoriba Jah leads a transdisciplinary research program in space safety, security, and sustainability at the University of Texas at Austin. He discusses ASTRIAGraph and its interesting use of a knowledge graph to help solve the problem of space junk.
GOING META – Ep 3: Controlling the Shape of your Graph With SHACLIn this third episode, Jesús Barrasa looks at how to keep the structure of a graph using a W3C standard called SHACL (Shape Constraint Language). SHACL is becoming quite popular as a framework to enhance data semantics. He explains the SHACL framework and demonstrates an example of it using Neo4j’s platform.
UNDER THE HOOD: The Multiple Faces of ComplexityScalability brings significant challenges to graph databases, whether it’s data volume or resource utilization. In this new video, Chris Gioran explores how to reframe this complexity in a more useful way and looks at sources and patterns to show how it manifests in graphs.
