Astronomy Picture of the Day: Wide Field View of Great American Eclipse
Wide Field View of Great American Eclipse Only in the fleeting darkness of a total solar eclipse is the light of the solar corona easily visible. Normally overwhelmed by the bright solar disk, the expansive corona, the sun's outer atmosphere, is an alluring sight. But the subtle details and extreme ranges in the corona's brightness, although discernible to the eye, are notoriously difficult to photograph. Pictured here, however, using over 120 images and meticulous digital processing, is a detailed wide-angle image of the Sun's corona taken during the Great American Eclipse in 2017 August. Clearly visible are intricate layers and glowing caustics of an ever changing mixture of hot gas and magnetic fields. Hundreds of stars as faint as 11th magnitude are visible behind the Moon and Sun, with Mars appearing in red on the far right. The next total eclipse of the Sun will occur on July 2 and be visible during sunset from a thin swath across Chile and Argentina.

The LG LW8016ERis a top choice for an office or den, and some people will find it quiet enough for a bedroom, too.If our main pick is sold out, grab the Frigidaire FFRE0833S1. It's a little bit louder and higher-pitched than our new pick, but it's an …
Lenovo is announcing a pair of new laptops today, the Yoga 730 and Flex 14, both of which are seeing a number of small design tweaks and receiving Intel’s 8th gen processors. While there aren’t any major changes this year, the 730 is getting one notable improvement to help it stand out: it has built-in far-field mics so that it can support Alexa.The Yoga 730 is really similar to last year’s Yoga 720: like all Yoga laptops, it has a touchscreen and can flip around into tablet mode; it starts with a price around $900 but can go much higher if you spec it out; and while it’s a well-made laptop with an aluminum body, it isn’t quite as slim or light as what Lenovo offers in its Yoga 900 series laptops.
