About this episode

Astronomers investigate a mysterious shock wave around the dead star RXJ0528+2838, revealing potential hidden energy sources.

Astronomers are surprised by a mysterious shock wave around the dead star RXJ0528+2838, studied with ESO’s Very Large Telescope. The dead star moves through space creating a so-called bow shock, as the surrounding material is pushed away. Structures like this one are typically caused by a strong outflow from the star. However, in the case of RXJ0528+2838, no known mechanism could be causing the outflow. A hidden energy source, perhaps magnetic fields, might be the answer to this mystery.
