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

A ginormous solar tornado and a massive eruption of plasma have been observed occurring at the same time on the sun — a phenomenon so strange and rare that it's challenging previously held theories. Both phenomena were snapped in the same photograph by the Institute of Space Science in Romania researcher Maximilian Teodorescu on Aug. 20. Solar tornadoes and plasma eruptions seem dramatic but are in fact the offshoots of changing in the sun's invisible magnetic field. They're unrelated, but to view them together is extraordinary and a thrill for scientists.

Why Solar Tornadoes and Eruptions Matter

As per Live Science, the solar tornado was enormous — it clocked in at about 130,000 kilometers (nearly 80,000 miles) tall. That's higher than stacking over 10 Earths on top of one another. Solar tornadoes tend to be much smaller, around 25,000 to 100,000 kilometers high. In addition to it, Teodorescu also imaged an eruptive prominence that measured some 200,000 kilometers across – about the same size as another famous prominence — called “The Beast” — that we photographed in July.

Solar tornadoes don't spin like terrestrial ones. And what blows is not air and wind but super-hot plasma, pinched in place by the Sun's magnetic field. If instability is dominant, plasma will escape the field into space as an eruptive prominence. The sun has a case of gas every so often, in the form of clouds of solar plasma, known as coronal mass ejections, or CMEs, that can buffet Earth's magnetic field and cause its magnetic lines to erupt, sending auroras sparking across the sky and wreaking havoc on satellites. Good news? This CME is not aimed at Earth.

The event was seen by Teodorescu using the Global Oscillation Network Group (GONG), a series of telescopes around the world that stare at the sun. His wife, Eliza, also a scientist, helped “on the ground,” orienting the telescope for a clearer shot. The Sun is currently at solar maximum, the most tempestuous point in the 11-year solar cycle.

Which is to say there are probably more tornadoes, eruptions and CMEs in store. Some scientists are calling it one of the most exciting times to safely observe the Sun through solar equipment.

CSIRO Uses Quantum AI to Revolutionize Semiconductor Design

Researchers at Australia's CSIRO have achieved a world-first demonstration of quantum machine learning in semiconductor fabrication. The quantum-enhanced model outperformed conventional AI methods and could reshape how microchips are designed. The team focused on modeling a crucial—but hard to predict—property called “Ohmic contact” resistance, which measures how easily current flows where metal meets a semiconductor. They analysed 159 experimental samples from advanced gallium nitride (GaN) transistors (known for high power/high-frequency performance). By combining a quantum processing layer with a final classical regression step, the model extracted subtle patterns that traditional approaches had missed. Tackling a difficult design problem According to the study, the CSIRO researchers first encoded many fabrication variables (like gas mixtures and annealing times) per device and used principal component analysis (PCA) to shrink 37 parameters down to the five most important ones. ...

Hubble Uncovers Multi-Age Stars in Ancient Cluster, Reshaping Galaxy Origins

Astronomers call ancient star clusters like NGC 1786 “time capsules” for their galaxy, preserving some of its oldest stars. A new image from NASA's Hubble Space Telescope offers an unprecedented close-up of this dense cluster 160,000 light-years away in the Large Magellanic Cloud. Hubble's data show that NGC 1786 contains stars of different ages – a surprising find, since such clusters were once thought to hold a single stellar generation. This multi-age discovery is reshaping our view of how galaxies built their first stars, and suggests more complex early history. Mixed-Age Stars in a Galactic Time Capsule According to the official source, this Hubble image shows the globular cluster NGC 1786, a ball of densely packed stars in the Large Magellanic Cloud about 160,000 light-years from Earth. Astronomers captured this picture as part of a program comparing ancient clusters in nearby dwarf galaxies (like the LMC) with clusters in our own Milky Way. The surprising discovery is th...

A Planet with a Death Wish: How HIP 67522 b Is Forcing Its Star to Explode

Scientists have caught a planet with a death wish, which is an alien world, orbiting very near to its star, and so speedy that it is causing the star to go to its death with bursting explosions. HIP 67522 b is the planet, and it is of the same size as Jupiter with a seven-day orbit around its host star. These orbits are disturbing the magnetic field of the star and causing enormous blasting eruptions to blow back the planet and make it wrinkled. This is the first time that a planet is influencing the host star, as the astronomers reported in a study published on July 2, 2025, in the Journal Nature. A Planet with a Death Wish: HIP 67522 b's Fiery Orbit As per the study by NASA, Ekaterina Ilin, the first author of the study and an astrophysicist at the Netherlands Institute for Radio Astronomy, said that the planet was observed to trigger the energetic flares. It has been predicted by the scientists that the waves are setting off explosions that are going to happen. Magnetic Chaos: P...
