The sun in detail: Contorted center of sunspot nearly twice the size of Earth

New images have revealed otherwise invisible details of our Sun, including a new view of the dark, contorted center of a sunspot that is nearly twice the diameter of the Earth. The images are the first ever made of the Sun with a facility where ESO is a partner. The results are an important expansion of the range of observations that can be used to probe the physics of our nearest star.

Next-generation optics offer the widest real-time views of vast regions of the sun

A groundbreaking new optical device to correct images of the Sun distorted by multiple layers of atmospheric turbulence, is providing scientists with the most precisely detailed, real-time pictures to date of solar activity occurring across vast stretches of the star’s surface.

Solar storms could spark soils at moon's poles

Powerful solar storms can charge up the soil in frigid, permanently shadowed regions near the lunar poles, and may possibly produce ‘sparks’ that could vaporize and melt the soil, perhaps as much as meteoroid impacts, according to new research. This alteration may become evident when analyzing future samples from these regions that could hold the key to understanding the history of the moon and solar system.
