- he sunspot quickly evolved into an unstable configuration and could lead to solar flares, Nasa warns
- The agency’s Solar Dynamics Observatory watched it form in less than 48 hours over Tuesday and Wednesday
A giant sunspot that is at least six times the diameter of Earth has formed on the Sun in less than 48 hours, Nasa has announced.
Sunspots are dark spots on the surface of the Sun which appear as turbulent magnetic fields in its surface rearrange and realign.
The massive sunspot, which formed over the course of Tuesday and Wednesday, quickly evolved into an unstable configuration, and could lead to solar flares, which can interrupt our radio communications.
