Captured from just 3.8 million miles away, the footage shows chaotic collisions of solar eruptions, twisting magnetic fields, and the origin zones of the solar wind—phenomena that shape space weather and can disrupt life on Earth. This unprecedented view from inside the corona is helping scientists understand and predict the Sun’s violent behavior like never before.

This rare particle—never seen before and predicted not to exist within string theory—might leave behind vanishing tracks in the Large Hadron Collider, like ghostly footprints that suddenly disappear. Spotting it wouldn’t just shake up physics theory—it might also reveal clues to dark matter, the invisible stuff that makes up most of the universe.

Researchers captured never-before-seen bright and dark stripes—called striations—within solar granules. These features behave like magnetic curtains rippling across the Sun, reshaping our understanding of magnetic field dynamics at microscopic scales. By achieving a resolution of just 20 kilometers, scientists could match real observations with simulations, revealing subtle magnetic fluctuations that alter how we see the solar surface. These discoveries illuminate not only solar activity but also magnetic behaviors in faraway cosmic environments, with implications for predicting space weather on Earth.
