A NASA spacecraft has blasted off on a quest to explore Jupiter's moon Europa and reveal whether its hidden ocean might hold the keys to life.

We can expect additional aurora displays and potentially more impacts to technology over the next year or two, according to NASA and the National Oceanic and Atmospheric Administration.

Scientists at NASA and NOAA think the sun has reached the maximum phase of the solar cycle, which means another year — at least — of intense Northern Lights.

Experts have announced that the Sun has reached its solar maximum period, which could continue for the next year. Scientists will not be able to determine the exact peak of this solar maximum period for many months because it's only identifiable after they've tracked a consistent decline in solar activity after that peak.
