For decades, scientists have been baffled by why the Sun’s atmosphere is millions of degrees hotter than its surface. Now, researchers at the Instituto de Astrofísica de Canarias (IAC) have proposed a new model explaining how tiny plasma ejections, known as nanojets, could solve this mystery. Their work provides key predictions for future space missions to finally observe these elusive events.

The World Health Organization has reported the deaths of three people and several suspected cases of hantavirus on a luxury cruise ship bound for the Canary Islands. The MV Hondius departed from Ushuaia, Argentina, and was heading to Cape Verde before reaching the archipelago. Investigations are ongoing as health authorities coordinate medical evacuations.

The Canary Islands have officially launched their high-risk wildfire season, deploying nearly 2,000 firefighters, 208 vehicles and 18 aircraft. Despite a wet winter, persistent drought and climate change have left the archipelago’s forests dangerously dry, with officials warning that the land is effectively a powder keg.

New research reveals that during the Eemian interglacial period, sea levels in the Canary Islands rose by up to 8 metres, wiping out ancient shorelines. Scientists warn that current climate change could trigger a similar, slow but inevitable, rise over coming centuries, reshaping the archipelago’s coast.
