The source is a news article from Live Science discussing a new NASA study about the Sun's activity. The article reports that NASA scientists are warning of decades of potentially dangerous space weather because the Sun is "waking up" from a quiet period, contradicting earlier predictions that activity was decreasing. This resurgence, evidenced by an upward trend in solar wind, magnetic field strength, and sunspots since 2008, suggests the theory of an impending "deep solar minimum" is incorrect. The text highlights that the current sunspot cycle has been more active than expected, producing a record number of powerful solar flares and major geomagnetic storms, which poses a threat to increasingly reliant modern technology like power grids and satellites. Researchers admit they do not fully understand the long-term fluctuations driving this renewed activity.
