NASA satellites captured a stunning "polar crown filament" erupting from the sun. ... On the sun, though, 55 degrees marks the boundary between zones of different magnetic structure.

NASA launches probe on historic mission to study the sun 02:38. NASA instruments captured the moment part of the sun appeared to break off from the giant star and get swept up in a polar vortex.

Even on the summer solstice, the sun never climbs more than 42 degrees above the horizon in Utqiagvik — that’s the same sun angle one would see in Washington on Feb. 25.

The gravity bump will give the spacecraft its first chance to see the sun's polar regions. A flyby in June 2029 will increase its angle to 33 degrees. Inside NASA's daring mission to touch the sun ...

Until now, all the pictures of the sun have been straight-on head shots. Soon, scientists will be getting a profile. NASA and the European Space Agency are set to launch a joint mission on Sunday ...

The gravity-assist flybys will eventually raise the tilt of the probe's orbit with respect to the sun's equator by about 35 degrees, enabling the spacecraft to "see" the star's polar regions.

ESA’s Solar Orbiter will be the first spacecraft to study the sun’s polar zones. A new solar mission will help solve some of our star’s thorniest mysteries.

The North Polar Spur (NPS), described by NASA as "the most spectacular coherent structure in the soft X-ray sky," and the Fan Region are two of the brightest radio-emitting gas structures seen in ...
