Sun releases largest solar radiation storm in over 20 years

The sun sure has woken up this week, unleashing a powerful X-class solar flare on Jan. 18 that hurled a colossal, fast-moving coronal mass ejection (CME) directly toward Earth. That CME has now arrived, triggering severe (G4) geomagnetic storm conditions far earlier than initially forecast.
The Sun has released the strongest solar radiation storm in more than 20 years, triggering auroras across Europe and raising concerns over satellite, aviation, and astronaut safety. The solar storm — which is the largest in over two decades — is the outcome of a mass eruption of charged particles that left the sun on Sunday.
An X-class solar flare has produced an Earth-directed coronal mass ejection, increasing solar activity and raising the likelihood of geomagnetic impacts within 24 hours.
Research conducted by an international team of astronomers from Southwest Research Institute, Aryabhatta Research Institute of Observational Sciences in India and the Max Planck Institute in Germany could help predict upcoming solar cycle activity.
The sun has become more and more active over the last 16 years, in a turn that surprised scientists and could affect space weather and technology on Earth, NASA announced this week. A new research, conducted by two NASA scientists and published earlier in ...
We all rely on the sun to supply our planet with light and warmth, but despite it being vital to our continued existence, there's a lot that scientists still don't know about it. A new study has surprised scientists at NASA by showing that the sun's ...
New research suggests that the unexpected intensity of the ongoing solar maximum may be partly tied to a lesser-known, 100-year solar cycle. If true, solar activity could spike further in the coming decades. But some experts are skeptical. When you ...
