Newfound Cosmic ‘Gateway’ Funnels Small, Icy Objects to the Inner Solar System

Beginning as small, icy bodies on the outskirts of the solar system, comets turn into spectacular streaks of light when they pass through a "gateway" near Jupiter, according to new research. LIVESCIENCE This gateway is a region of space where objects called centaurs — small, icy bodies that orbit between Jupiter and Neptune — start to nudge closer to the sun. As they do so, they heat up and become “active,” primarily releasing a dusty halo of gas — which makes these small bodies, technically...

Solar Spike Suggests a More Active Sun

Radio waves are providing a new way to probe the Sun and suggest that the magnetic field of its corona may be stronger than long thought. EOS.ORG At about the same time the Sun was blowing off the largest flare measured in over a decade, the strength of the magnetic field in its atmosphere hit a record high. But that may not be abnormal. New research suggests that the Sun’s magnetic field may climb to levels of intensity stronger than currently predicted, a discovery that could have impli...

NASA Satellite Spots Mysterious Lights in Deep Space That Quickly Disappear

Solar flares and full moons affect human behavior. Could these mysterious flashing lights also be affecting the humans down on the ground? MYSTERIOUS UNIVERSE We’ve been seeing some weird stuff happening in deep space recently. First, the supermassive black hole at the center of the Milky Way lit up for some unknown reason, and now NASA says they’ve detected mysterious green and blue blobs of light that appeared near the center of the “Fireworks galaxy” and disappeared just as quickly. If al...

Geomagnetic Disturbances and Cardiovascular Mortality Risk

Short-term geomagnetic disturbances driven by solar activity have been linked to a broad range of adverse health effects. Carolina Leticia Zilli Vieira In this blog, author Carolina Leticia Zilli Vieira discusses her recent article, published in Environmental Health, which looks at the effects of GMD on cardiovascular diseases, myocardial infarction, and stroke in 263 U.S. Cities. Daily geomagnetic disturbances, or geomagnetic storms, are temporary distortions in the Earth’s magnetic fiel...
