  Massive Sunspot Complex on the Sun Raises Risk of Strong Solar Storms

  A massive sunspot complex has appeared on the Sun, covering an area comparable to the legendary Carrington Event region. Known as AR 4294-96, the active cluster features highly tangled magnetic fields that could unleash powerful solar flares and geomagnetic storms, potentially disrupting satellites, power grids, and global communications if Earth-d...

  Rare Giant Solar Tornado and Plasma Eruption Captured Together on the Sun

  A Romanian researcher captured a rare sight on the Sun — a giant solar tornado alongside a massive plasma eruption. Both events, driven by magnetic field changes, highlight the Sun’s extreme activity during solar maximum. Luckily, the eruption’s CME is not headed toward Earth.

  Colossal Solar Filament Eruption Sculpts 250,000-Mile 'Canyon of Fire' on the Sun’s Surface

  A massive July 15 filament eruption from the sun’s limb carved a 250,000‑mile‑long plasma canyon captured by NASA’s SDO. The spectacular rift, formed as magnetic fields realigned, featured 12,400‑mile‑high plasma walls. Although the eruption launched a coronal mass ejection into space, SOHO and GOES‑19 imagery confirm it’s heading a...

  NSF’s DKIST Captures Sharpest-Ever Images of Fine Solar Magnetic Striations

  Using the NSF’s Daniel K. Inouye Solar Telescope, scientists have captured the most detailed views of the Sun’s surface ever recorded. The new observations reveal ultra-narrow magnetic striations only 20 kilometers wide, etched into solar granules. These light and dark bands reflect subtle variations in magnetic field strength. Researchers say ...

  Parker Solar Probe Witnesses Unprecedented Sunward Plasma Jet Driven by Magnetic Reconnection

  NASA's Parker Solar Probe has made a groundbreaking discovery, observing an unprecedented plasma explosion in the Sun's corona. This rare event produced a sunward jet of particles, with protons accelerated to nearly 1,000 times the expected energy. Scientists traced this phenomenon back to a magnetic reconnection site, where twisted solar magnetic ...

  Study Explores Sun’s Magnetic Field Changes and Solar Wind Acceleration

  A study published in The Astrophysical Journal has shed light on how the Sun’s magnetic field influences solar wind acceleration. Using data from the Parker Solar Probe and Solar Orbiter, researchers observed that sharp magnetic switchbacks smooth out into gentler waves as they travel further from the Sun. This relaxation process transfers magnet...

  Solar Orbiter Sends High-Resolution Images of Sun’s Surface, Unveiling New Details

  The Solar Orbiter spacecraft has sent back the sharpest images of the sun’s surface, captured from 74 million kilometres away. These high-resolution images reveal the sun’s dynamic surface features, including granular patterns and sunspots. The spacecraft’s instruments also provided detailed maps of the sun’s magnetic fields, shedding light...

  NASA's Parker Solar Probe Unveils New Insights into Solar Heating Mystery

  NASA's Parker Solar Probe has delivered groundbreaking insights into one of the sun's most perplexing mysteries: why its outer atmosphere, or corona, is significantly hotter than its surface. This phenomenon, known as the "coronal heating mystery," has puzzled scientists for decades. The Parker Solar Probe, which is the fastest human-made object, h...

  NASA Explains How Intense Geomagnetic Storms Lead to Stunning Auroras

  The National Oceanic and Atmospheric Administration (NOAA) has issued a warning about an intense geomagnetic storm at level G4, which is likely to disrupt power grids, GPS, and radio signals. Despite these potential issues, the storm offers a remarkable visual treat with colourful auroras visible in high-latitude areas of Canada and the United Stat...

  Sun's Magnetic Field May Originate Closer To Solar Surface: Study

  The sun's magnetic field, which causes solar storms like the one that hit Earth this month and produced beautiful auroras, may originate at shallower depths in the star's interior than previously thought, according to researchers.

  Solar Flares Seen During Total Solar Eclipse. Here's What It Means

  A solar flare is a massive explosion that occurs on the Sun when energy that has been trapped in "twisted" magnetic fields, which are often found above sunspots, is abruptly released.
