Visualising the Sun’s neighbourhood in 3-D

Astronomers have used modern techniques to create a 3-D visualisation of all of the O- and B-type stars within 500 parsecs (1,630 light-years) of the Sun using data from ESA’s Hipparcos satellite. This new visualisation uncovers evidence for new structures in the distribution of these nearby hot stars, and new and surprising theories of how those stars formed.
