Image: SDO sees 3 coronal 'holes'
The sun was visually dominated by three substantial coronal holes that rotated across its face the week of Sept. 8-10, 2015. Coronal holes are areas where the sun's magnetic field lines extend out into space and don't return ...

Video: A golden arch on the sun
Magnetically charged particles formed a nicely symmetrical arch at the edge of the sun as they followed the magnetic field lines of an active region on Aug.4-5, 2015. Before long the arch begins to fade, but a fainter and ...

Short wavelength plasmons observed in nanotubes
The term "plasmons" might sound like something from the soon-to-be-released new Star Wars movie, but the effects of plasmons have been known about for centuries. Plasmons are collective oscillations of conduction electrons ...

High UV sensitivity in hooded seal eyes improves polar bear detection
Researchers have shown that hooded seals native to the Arctic Ocean and North Atlantic have eyes that are extremely sensitive to ultraviolet (UV) light, enabling them to spot polar bears that would usually be camouflaged ...

Mission studies the Sun in soft X-rays
At any given moment, our sun emits a range of light waves far more expansive than what our eyes alone can see: from visible light to extreme ultraviolet to soft and hard X-rays. Different wavelengths can have different effects ...
