Scientists Detect Hidden Magnetic Waves That Could Explain the Sun’s Mysterious Heat
For the first time, scientists have directly observed twisting Alfvén waves in the Sun’s corona using the Inouye Solar Telescope. The discovery could explain why the Sun’s outer atmosphere is millions of degrees hotter than its surface, offering key insights into solar energy transfer and space weather prediction.

Scientists Construct 5-Micron Engine Generating Effective Heat of 13 Million Degrees Celsius Without Burning
A team of scientists has created a microscopic engine made from a 5-micrometre glass bead suspended in an electric field. By applying oscillating voltages, the bead moves as if it’s in an environment of 13 million°C, even though it remains cool. The study reveals bizarre thermodynamic effects at tiny scales, offering clues to how natural molecul...

Scientists Say Solar Flares Are Hotter Than Expected, Could Reach 108 Million Degrees
A groundbreaking study shows ions in solar flares can reach 108 million°F, about six times hotter than earlier estimates. The research explains decades-old mysteries in flare spectra and urges new “multi-temperature” models to better forecast space weather, protecting satellites, astronauts, and communications from hazardous solar storms.

10 Strange 'Dark Voids' Appear Over Remote Island Near Antarctica in Rare Satellite View
A rare NASA satellite image shows 10 sharply defined “dark voids” above Heard Island, a volcanic peak in the southern Indian Ocean. Formed by von Kármán vortices bent nearly 90 degrees by fierce westerly winds, the striking gaps pierce thick cloud cover, offering a vivid glimpse of nature’s intricate atmospheric patterns from space.

NASA’s IXPE Challenges Theories on Black Hole Corona and Polarised X-Ray Emissions
NASA’s Imaging X-ray Polarimetry Explorer (IXPE) has made surprising observations in a black hole binary system, detecting a high degree of X-ray polarisation that challenges current models of corona structure and accretion discs. In X-ray binaries, black holes pull matter from nearby stars, forming hot accretion discs and coronas.

Screams, Prayers As Saudi Amusement Park Ride Crashes On Camera
At least 23 people were injured, some seriously, after a ride in an amusement park in Saudi Arabia's Taif malfunctioned and broke into two.

See a Wafer-Thin Crescent Moon Leapfrog Jupiter in the Post-Sunset Sky This Week
Skywatchers can catch a fleeting celestial display as a wafer-thin crescent moon appears near Jupiter in the western sky on April 29 and 30. The moon will leap to Jupiter’s upper right by April 30 evening, with just over five degrees separating the two. Earthshine and nearby stars add to this picturesque twilight event visible shortly after sunse...

Bizzare 'Failed Star' Planet Orbiting Double Star System in Milky Way Discovered by Researchers
Astronomers have discovered an exoplanet 90 degrees tilted around a special pair of eclipsing brown dwarfs. This uncommon "polar planet" challenges accepted wisdom on planet creation by presenting new insights on the dynamics of binary stars and the range of Milky Way planetary orbits.

Wolf-Rayet 104's Orbit Tilt Reduces Gamma-Ray Burst Threat, Study Finds
New research using Keck Observatory’s instruments confirms that the orbit of Wolf-Rayet 104 is tilted 30-40 degrees away from Earth, lowering concerns about a possible gamma-ray burst. Previously, it was believed that the system’s alignment could pose a risk. However, spectroscopy data now challenges these assumptions, raising new questions abo...
