Solar modulation of galactic cosmic ray flux on the wane? Something extraordinary is happening

Coronal holes rarely made the news during Solar Cycle 23. Solar Cycle 24, however, is a different story. As early as August 2013, in the middle of this solar cycle’s "double hump" maximum, a Fox News correspondent asked Corey Powell of Discover...

Energy from Space - The Shift Has Begun

Earth and Sun's fields are weakening and we're exiting the magnetic dust cloud. At the same time, our three shields against energy from space are disappearing, we are showing increased vulnerability to space weather from our sun, and cosmic rays are already...

How cosmic rays produce clouds and influence Earth's climate

A new study published in Nature Communications this week reveals how atmospheric ions, produced by the energetic cosmic rays raining down through the atmosphere, helps the growth and formation of cloud condensation nuclei - the seeds necessary for forming clouds in...

Atmospheric radiation increasing as we head into Solar Minimum

Cosmic rays from deep space are increasing almost unabated as the Sun's magnetic field weakens and we head into Solar Minimum. As reported by Spaceweather.com, the stratospheric balloons they've been flying together with the students of Earth to Sky...

Gamma-ray telescopes reveal a high-energy trap in our galaxy's center

A combined analysis of data from NASA's Fermi Gamma-ray Space Telescope and the High Energy Stereoscopic System (H.E.S.S.), a ground-based observatory in Namibia, suggests the center of our Milky Way contains a "trap" that concentrates some of the...

Intensifying cosmic rays, grand solar minimum and Earth's climate

Data provided by the students of Earth to Sky Calculus and Dr. Tony Phillips of SpaceWeather.com show cosmic ray levels are intensifying, as the Solar Minimum approaches, with an approximately 13% increase since March 2015. This article provides a brief overview of...

New data show heliosphere is nearly round and symmetrical

New data covering an entire 11-year solar activity cycle suggest that Sun and planets in our solar system are surrounded by a giant, spherical system of magnetic field from the Sun, calling into question the current view of the solar magnetic fields trailing behind...

A hotspot for powerful cosmic rays

Physicists a step closer to finding mysterious sources...An observatory run by the University of Utah found a "hotspot" beneath the Big Dipper emitting a disproportionate number of the highest-energy cosmic rays. The discovery moves physics another step

Fermi proves supernova remnants produce cosmic rays

A new study using observations from NASA's Fermi Gamma-ray Space Telescope reveals the first clear-cut evidence that the expanding debris of exploded stars produces some of the fastest-moving matter in the universe. This discovery is a major step toward meeting one of

Antiproton ring found around Earth

Antiprotons appear to ring the Earth, confined by the planet's magnetic field lines. The antimatter, which may persist for minutes or hours before annihilating with normal matter, could in theory be used to fuel ultra-efficient rockets of the future.Charged particle
