Star With a ‘StacheImage courtesy NASA/JPL-Caltech/UCLA

Seen in visible light, the star known as Zeta Ophiuchi is dim, red, and surrounded by inky blackness. But in infrared the star becomes a bright blue ball of fire topped with a glowing “mustache” of interstellar dust, as seen in a new picture from NASA’s Wide-field Infrared Survey Explorer, or WISE, telescope.

Astronomers think Zeta Ophiuchi was once part of a stellar duo known as a binary pair. Then the companion star exploded, releasing Zeta Ophiuchi to go flying away on a fast-tracked solo act through space. The star is now plowing through a cloud of dust and gas at 15 miles (24 kilometers) a second. As the star moves, its powerful radiation is compressing the gas and dust in its path, creating a bow shock that shines in infrared.
Leave a Light On

The solar ejections that cause auroras can also create geomagnetic storms that can affect spacewalking astronauts, Earth-orbiting satellites, and even communications and power systems on the ground.
Kryptonite Haze

The glowing display of curtains, arcs, and bands in the sky is called aurora borealis, or northern lights, in the Northern Hemisphere and aurora australis, or southern lights, in the Southern Hemisphere.

Photograph by Randall Scholten, Your ShotA quaint and cozy little seafood restaurant on the commercial dock in Port Orford, Oregon, is all decked out for the holidays in this photo taken at first light. Life in this small, rustic fishing village is frozen in the past when life was much less hectic and when the simple pleasures of life were still noticed and appreciated.
