Cosmic rays decreasing as Solar Cycle 25 gains strength

New data provided by the students of Earth to Sky Calculus and Dr. Tony Phillips of SpaceWeather.com show that cosmic radiation levels in the Earth's atmosphere are decreasing as the new solar cycle -- Solar Cycle 25 -- gains strength. The plot below shows...

New observations of coronal mass ejections and cosmic rays

Scientists have released new observations of solar activities, such as Coronal Mass Ejections (CMEs) and cosmic rays, gathered by the Global Muon Detector Network (GMDN) at the Syowa Station in the Antarctic. The team found that high-speed solar wind causes the...

Cosmic rays increase remarkably as solar activity shows persistent decline, resembles Dalton minimum of 1790 - 1830

Recent solar conditions indicate a persistent decline in solar activity‐‐‐possibly similar to the past solar grand minima, scientists reporting in AGU's Space Weather write. During such periods of low solar activity, the fluxes of galactic cosmic rays...

Deep-space radiation reaching a percentage point of Space Age maximum

Solar activity is at very low levels and the visible disk remains spotless for the 17th day in a row, making a total of 33 days in 2020 or 66 percent -- we are still in a Solar Minimum, which is expected to end sometime this year. As a result of weakened Sun's...

Unsettled geomagnetic field due to CH HSS influences

Solar wind parameters in 24 hours ending 12:30 UTC today were indicative of a slightly enhanced and disturbed interplanetary magnetic field (IMF) due to weak coronal hole high speed stream (CH HSS) influences. Total IMF strength was variable, but steadily increased...

Galactic cosmic rays affect atmosphere of Saturn's moon Titan, research finds

A team of Japanese researchers-- using data from the Atacama Large Millimeter/submillimeter Array (ALMA)-- discovered that galactic cosmic rays affect the chemical reactions involved in the formation of organic molecules bearing nitrogen on the atmosphere of...

Cosmic radiation around us reaching record high levels as the Sun sets Space Age record for most days without spots

Cosmic radiation has hit the 5-year high this month and is approaching record high values as the Sun sets a new Space Age record for spotlessness -- days without sunspots. The Sun’s magnetic field weakens during solar minimums, allowing deep space cosmic...

Cosmic rays in Earth's atmosphere intensifying for the fourth year in a row

Cosmic rays in Earth's atmosphere are intensifying for the 4th year in a row as the 11-year solar cycle plunges into one of the deepest minima of the Space Age. The finding comes from a campaign of almost weekly high-altitude balloon launches conducted by the...

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...

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...
