A massive “hole,” up to 20 times bigger than Earth, has appeared on the surface of the sun for the second time in a week and scientists are warning that it could impact our planet.
Last week, the Earth saw the results of the worst solar storm in six years, when a G4-class geomagnetic event lit up Canadian skies with auroras, many of which were visible as far south as New Mexico in the U.S.
Now, researchers say this new coronal hole could send solar winds at speeds of up to 2.9 million kilometres per hour toward Earth by the end of the week.
NASA’s Solar Dynamics Observatory spotted the coronal hole, which is a completely normal phenomenon, but the placement of this particular hole is what makes it unique.
