Huge solar filament stretches across the Sun

What has been billed as the largest sunspot observed in several years has now rotated around to stare straight at Earth. How large is it? Active Region 1339 and the group of sunspots adjacent to it extends ...

Fast-growing sunspot 1112 is crackling with solar flares.

An enormous triangular hole in the Sun’s corona was captured earlier today by NASA’s Solar Dynamics Observatory, seen above from the AIA 211 imaging assembly. This gap in the Sun’s atmosphere ...

(PhysOrg.com) -- NASA's Solar Dynamics Observatory (SDO) captured this image of an M7.9 class flare on March 13, 2012 at 1:29 p.m. EDT. It is shown here in the 131 Angstrom wavelength, a wavelength particularly ...

(Phys.org) -- A light bulb-shaped eruption leaps from the Sun and blasts into space in this archival image from the ESA/NASA Solar and Heliospheric Observatory, SOHO.   SOHO captured the scene on 27 Febru ...

The short answer? Really big. The long answer? Really, really big.

Coronal mass ejections (CMEs), emissions of magnetized ionized gas from the Sun, can damage satellites and communication technology, so being able to predict where they are heading and how much energy they ...

(Phys.org) —Saturn's moon Titan might be in for some wild weather as it heads into its spring and summer, if two new models are correct. Scientists think that as the seasons change in Titan's northern hemisphere, ...

UPDATE 16:30 p.m. EDT: The M7-class flare was also associated with a coronal mass ejection or CME, another solar phenomenon that can send billions of tons of particles into space. While this CME was not Ea ...

An Ecuadoran satellite launched last month could collide with the remains of a Russian rocket in the coming hours, the country's civilian space agency warned.

Even though astronauts receive some general medical training in preparation for a stay aboard the ISS, most of them still aren't medical professionals by any means—and with the inherent difficulties of ...

(Phys.org) —The time draws near. NASA is getting ready to launch a new mission, a mission to observe a largely unexplored region of the solar atmosphere that powers its dynamic million-degree outer atmosphere and drives ...
