ClimarisQ: A game on the complexity of the climate systems and the extreme events

ClimarisQ: A game on the complexity of the climate systems and the extreme events

ClimarisQ is a smartphone/web game from a scientific mediation project that highlights the complexity of the climate system and the urgency of collective action to limit climate change. It is available in four languages: English, French, Spanish and Italian. It is an app-game where players must make decisions to limit the frequency and impacts of …[Read More]

Resolving the very fine details of the Sun in low frequency radio

Radio images of the Sun taken by a range of radio observatories at different frequencies.

The Sun is an active radio emitter, it produces radio emissions in a wide frequency range from kHz to THz. The solar atmosphere has a complex distribution of magnetic field, plasma density, and temperature. These different properties of the solar atmosphere will result in different radio emission features at different frequencies. In principle, the plasma …[Read More]

Initiation and Heliospheric Evolution of a stealthy solar eruption

A schematic of the ICME flux rope cross-section and the large-scale magnetic structure draping about the ICME obtained based on the PSP observation.

In the early 1970s, when Coronal mass ejections (CMEs), massive eruptions of magnetized solar plasma into interplanetary space, were first discovered, they were assumed to be always associated with the energetic solar phenomenon like solar flares, prominences, etc. With improved coronagraphic and multi-wavelength observational instruments, a class of CMEs emerging from the streamers was found …[Read More]
