Astronomers have discovered a “gigantic cavity” in space, shedding light on how stars form. The sphere-shaped void spans about 150 parsecs – nearly 500 light years – and is located among the Perseus and Taurus constellations. Researchers believe the cavity was formed by an ancient supernovae – explosion of stars – that went off some 10 million years ago. It is surrounded by the Perseus and Taurus molecular clouds, which are regions in space where stars form. The discovery was made by astronomers analysing 3D maps of the shapes and sizes of nearby molecular clouds.
