Space weather model could determine exoplanetary habitable zones

A refinement to a space weather model developed by a center director at the University of Alabama in Huntsville (UAH) could help scientists check out which planets outside our solar system are likely to have someone home.

Image: Coronal mass ejection creates spooky Halloween sky

Eerie sheets and ripples of green hang above a deserted rocky landscape in this spooky Space Science Image of the Week. Spikes of neon and emerald seem to form the ominous form of a ghostly celestial eagle, with a sharp beak, ...

Three X-class flares in 24 hours

The sun emitted a third significant solar flare in under 24 hours, peaking at 9:11 p.m. EDT on May 13, 2013. This flare is classified as an X3.2 flare. This is the strongest X-class flare of 2013 so far, surpassing in strength ...

Sunrise II: A second look at the Sun

scillating fibrils, explosive increases in temperature, and the footprints of coronal loops: 13 articles published today provide an overview of the results of the second flight of the balloon-borne solar observatory Sunrise.

Indian scientists make deepest radio images of the sun

The sun is the brightest object in the sky, and probably the most studied celestial object. Surprisingly, it still hosts mysteries that scientists have been trying to unravel for decades, for example, the origin of coronal ...

Image: Coronal hole on the sun

(Phys.org) -- This image of a coronal hole on the sun bears a remarkable resemblance to the 'Sesame Street' character Big Bird. Coronal holes are regions where the sun's corona is dark.

Face to face with sun-eclipsing Proba-3

Through exquisite, millimeter-scale, formation flying, the dual satellites making up ESA's Proba-3 will accomplish what was previously a space mission impossible: Cast a precisely held shadow from one platform to the other, ...

Image: NASA's Solar Dynamics Observatory watches a sunspot

On July 5, 2017, NASA's Solar Dynamics Observatory watched an active region—an area of intense and complex magnetic fields—rotate into view on the Sun. The satellite continued to track the region as it grew and eventually ...
