Members of the Bay Area Association of Disabled Sailors sail every weekend near San Francisco's Pier 40. The all-volunteer group serves people with a range of physical, developmental and mental disabilities.
If you think sailing at 40 mph sounds challenging, imagine doing it all alone without the use of your arms or legs, or without hearing or with limited vision. Every weekend in San Francisco, a group of sailors with disabilities does just that, taking to the water to push their bodies to the limit.
Cristina Rubke and her father, Chris, are members of the Bay Area Association of Disabled Sailors. On a recent Saturday, they were at San Francisco's Pier 40, where the dock is awash in activity.
Fawaz Gerges is a longtime observer of the Middle East and fears the United States is rushing to take military action in Syria.
Gerges, a professor of international relations at the London School of Economics and Political Science, says Assad’s use of force and likely use of chemical weapons against his people should not be tolerated.
The wildfire still burning north of Yosemite National Park — you know, the one that has charred 237,341 acres and was at one point one of the largest fires in recent California history — was started by a hunter's illegal fire.
The U.S. Forest Service said in a statement that its investigators had concluded that the Rim Fire "began when a hunter allowed an illegal fire to escape."
Authorities, said the Forest Service, have made no arrest and they are not releasing the name of the hunter.
NASA's Solar Dynamics Observatory captured this picture of the sun on June 18. The dark blue area in the upper left quadrant of the sun is a huge coronal hole more than 400,000 miles across. Coronal holes are areas of the sun's outermost atmospheric layer — the corona — where the magnetic field opens up and solar material quickly flows out.
This channel is especially good at showing areas where cooler, dense plumes of plasma above the visible surface of the sun are located. Many of these features either can't be seen or appear as dark lines in the other channels. The bright areas show places where the plasma has a high density.
This channel is particularly good at showing coronal loops — the arcs extending off the sun where plasma moves along magnetic field lines. The brightest spots seen here are places where the magnetic field near the surface is exceptionally strong.
This channel highlights the active region of the outer atmosphere of the sun. Active regions, solar flares, and coronal mass ejections will appear bright here. The dark areas, or coronal holes, are places where very little radiation is emitted; they are also the main source of solar wind particles.
This channel often shows a weblike pattern of bright areas that highlight places where bundles of magnetic field lines are concentrated. However, small areas with a lot of field lines will appear black, usually near sunspots and active regions.
This channel shows the features that our eyes would see if we could dim the sun's intensely bright light. This wavelength of light is visible to people as blue-indigo, although here it is shown in yellow. Sunspots stand out sharply here, and you can also see that the edge of the sun appears darker, a well-known effect called limb darkening.
This image shows the magnetic field directions near the surface of the sun. White and black areas indicate opposite magnetic polarities, with white showing north (outward) polarity and black showing south (inward) polarity.
This image highlights the outer atmosphere of the sun, called the corona, as well as hot flare plasma. Hot active regions, solar flares and coronal mass ejections appear bright here. The dark areas, called coronal holes, are places where very little radiation is emitted. But these holes are the main source of solar wind particles.
There's a hole in the sun's corona. But don't worry — that happens from time to time.
"A coronal hole is just a big, dark blotch that we see on the sun in our images," says Dean Pesnell, project scientist for NASA's Solar Dynamics Observatory. "We can only see them from space, because when we look at them [through] a regular telescope, they don't appear."
