Parker Solar Probe Reveals Solar Wind U-Turn Phenomenon
Bright Insight from a Solar Pioneer NASA’s Parker Solar Probe has once again pushed the boundaries of solar science, capturing the most detailed view yet of the solar wind as it escapes the Sun and then appears to loop back in a surprising U-turn. This closer look helps scientists better understand how material leaves the…

Finding the point of no return: mapping the Sun’s shifting, spiky boundary for the first time
Introduction: A closer look at the Sun’s untamed edge For the first time, scientists have produced highly detailed maps of the Sun’s outer atmosphere—the boundary where solar material breaks away from the Sun’s magnetic grip and flows into space. This shedding boundary, marked by a juggling of magnetic fields and fast-moving particles, is not a…

Finding the Point of No Return: Mapping the Sun’s Shifting Outer Boundary for the First Time
Unveiling a solar frontier For the first time, scientists have produced detailed maps of the Sun’s outer atmosphere—the tenuous edge where solar material breaks free from the Sun’s magnetic grip and streams into the solar wind. This boundary, long speculated about by solar physicists, is not a fixed line but a dynamic, spiky frontier that…

Northern Lights Watch: CME-Driven Aurora Possible Thursday Night
Thunderous Sun, Quiet Skies: What’s Driving This Aurora Watch Sky watchers in parts of Canada and the northern United States should keep an eye on the night sky Thursday, as space weather forecasters monitor a trio of coronal mass ejections (CMEs) heading toward Earth. When these massive bursts of solar plasma interact with Earth’s magnetic…

Solar Wind Sculpts Comet Lemmon’s Tail: Stunning Astrophotography Captures
Intro: A Comet in the Sun’s Wake Comet C/2025 A6, commonly known as Lemmon, has enthralled sky-watchers with a dramatic brightening in recent months. As it journeys toward perihelion on November 8, the 1,350-year orbital path will bring Lemmon closer to the Sun, and potentially into naked-eye view for observers under dark skies this October.…
