In a recent study the ByoPiC team takes advantage of the most recent X-ray survey, SRG/eROSITA, to confirm unambiguously the detection of an X-ray signal associated with thermal emission from a hot plasma in cosmic filaments.

This signal from only 460 filaments, located in the first 140 deg² survey published by the SRG/eROSITA collaboration, has allowed the density and temperature of the plasma to be constrained precisely.

The EUI (Extreme Ultraviolet Imager) instrument on board the Solar Orbiter mission keeps on revealing new types of phenomena in the solar atmosphere. Last in date, an event nicknamed ‘the snake’ features the propagation of a bright front at 170 km/s along a twisted structure know as a ‘filament’, a tube of cool plasma maintained above the surface in the hot corona by the magnetic field.
