Sweden's Day and Night of Astronomy (Astronomins dag och natt) has theme "Earth 2.0" with a focus on exoplanets, and a program of events, both digital and in real life.
Chalmers astronomer Carina Persson is one of three invited speakers in the national digital program for the festival, to be broadcast on astronominsdag.se.
Her colleagues Iskra Georgieva (Chalmers) and Oscar Barragán (University of Oxford) are also taking part in the digital program.
