Weak Solar Cycle: Cosmic rays increase 4th year in a row

Increased exposure for airline travelers at high altitudes. New data released by the Earth to Sky Calculus/Spaceweather.com high-altitude ballooning program show that atmospheric cosmic rays are intensifying for the 4th year in a row–an ironic side-effect of the decaying solar cycle. The new results are of interest to everyone from astronauts to air travelers. This…

Solar ‘tadpole-like’ jets seen with NASA’S IRIS add new clue to age-old mystery

From NASA/GODDARD SPACE FLIGHT CENTER Scientists have discovered tadpole-shaped jets coming out of regions with intense magnetic fields on the Sun. Unlike those living on Earth, these “tadpoles” — formally called pseudo-shocks — are made entirely of plasma, the electrically conducting material made of charged particles that account for an estimated 99 percent of the…

Evidence for a new fundamental constant of the sun

From NORTHUMBRIA UNIVERSITY and the “solar constant” department New research undertaken at Northumbria University, Newcastle shows that the Sun’s magnetic waves behave differently than currently believed. Their findings have been reported in the latest edition of the prominent journal, Nature Astronomy. After examining data gathered over a 10-year period, the team from Northumbria’s Department of Mathematics, Physics…

Spotless Sun Sparks a Geomagnetic Storm

Right now, solar Minimum is in full swing. As you can see, the sun is completely spotless. But, last night the spotless sun produced a G1-class geomagnetic storm with bright auroras reported from Iceland to Alaska.  More lights are in the offing as a stream of solar wind is expected to buffet Earth’s magnetic field…

It’s the gradient, stupid!

How does the Sun drive climate change? Guest Post by Javier The dispute between scholars that favor a periodical interpretation of climate changes, mostly based on astronomical causes, and those that prefer non-periodical Earth-based explanations has a long tradition that can be traced to the catastrophism-uniformitarianism dispute and how the theory of ice ages (now termed glaciations)…
