The mystery of nanoflares

When you attach the prefix "nano" to something, it usually means "very small." Solar flares appear to be the exception.

Nanoparticle breakthrough in the fight against cancer

A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has introduced a novel targeted drug delivery system in the fight against cancer.

Hinode, IRIS, and ATERUI cooperate on 70 year old solar mystery

Solar physicists have captured the first direct observational signatures of resonant absorption, thought to play an important role in solving the "coronal heating problem" which has defied explanation for over 70 years.

Hinode satellite captures X-ray footage of solar eclipse

The moon passed between the Earth and the sun on Thursday, Oct. 23. While avid stargazers in North America looked up to watch the spectacle, the best vantage point was several hundred miles above the North Pole.

First observation of a focused plasma wave on the sun

For the first time, scientists have observed plasma waves from a solar flare focused by a coronal hole, akin to the focusing of sound waves responsible for the Rotunda effect in architecture or the focusing of light by a ...

Researchers explain magnetic field misbehavior in solar flares

When a solar flare filled with charged particles erupts from the sun, its magnetic fields sometime break a widely accepted rule of physics. The flux-freezing theorem dictates that the magnetic lines of force should flow away ...

Image: Giant filament seen on the sun

A dark, snaking line across the lower half of the sun in this Feb. 10, 2015 image from NASA's Solar Dynamics Observatory (SDO) shows a filament of solar material hovering above the sun's surface. SDO shows colder material ...
