Solar flares

Scientists come up with completely opposite theories about why the sun is weakening

For the last few years the sun has been kicking back and relaxing. A lot. Although a huge solar flare recently made headlines, the surface of the sun has been quiet lately. Sunspots have been more scarce than they’ve been in the last 200 years. All solar activity is low. And it looks like it’s…

Watch a monstrously prominent solar flare burst out of the Sun

It’s been a busy months for solar flares. On Thursday, NASA’s Solar Dynamics Observatory photographed this billowing plasma tower they’ve dubbed a “monster prominence.” For 90 minutes, this flare twisted on the Sun’s surface before collapsing and emitting material into space. https://gizmodo.com/the-sun-unleashes-its-biggest-solar-flare-in-years-5763289 Here’s NASA’s method of recording this flare, which erupted over an area known…

The Sun is changing the rate of radioactive decay, and breaking the rules of chemistry

The Sun is changing the supposedly constant rates of decay of radioactive elements, and we have absolutely no idea why. But an entirely unknown particle could be behind it. Plus, this discovery could help us predict deadly solar flares. It’s one of the most basic concepts in all of chemistry: Radioactive elements decay at a…

Can This Experiment Prevent Solar Flares From Destroying The World?

NASA recently launched a probe that’s designed to do nothing but study the sun — and it’s found new ways of helping scientists observe “violent solar events.” Which could be useful for predicting mega-flares. The Solar Dynamics Observatory, which NASA launched this past February, was built by the Goddard Space Flight Center for the express…

Huge Hole Found on Earth’s Magnetic Field, Run Around In Panic Now

NASA’s Themis, a satellite flotilla studying geomagnetic disturbances, have discovered a large hole on Earth’s magnetic field, which protects us against solar particles, which can cause severe disturbances in power grids, computers, and communication. Updated. https://gizmodo.com/themis-satellites-discover-northern-lights-are-powered-5028889 What we observed was the breach in the levee. This has taken us completely by surprise. The opening was…
