3 California Counties Voting on Fracking Bans by THE ASSOCIATED PRESS


By THE ASSOCIATED PRESS

Voters in three coastal California counties vote Tuesday on whether to ban fracking and other intensive oil production, even as slumping prices globally are leading companies to start to scale back on production.

A Company Caught Between a Hostile Bid and a Side Deal by STEVEN DAVIDOFF SOLOMON


By STEVEN DAVIDOFF SOLOMON

The battle for the GFI Group, a New York brokerage and clearing firm, features an insider transaction, the secret accumulation of shares and a hostile offer that may be something else entirely, Steven Davidoff Solomon writes in the Deal Professor…

A Spectre in the Eastern Veil

Frightening forms and scary faces are a mark of the Halloween season. They also haunt this cosmic close-up of the eastern Veil Nebula. The Veil Nebula itself is a large supernova remnant, the expanding debris cloud from the death explosion of a massive star. While the Veil is roughly circular in shape and covers nearly 3 degrees on the sky in the constellation Cygnus, this portion of the eastern Veil spans only 1/2 degree, about the apparent size of the Moon. That translates to 12 light-years at the Veil’s estimated distance, a reassuring 1,400 light-years from planet Earth. In the composite of image data recorded through broad and narrow band filters, emission from hydrogen atoms in the remnant is shown in red with strong emission from oxygen atoms in blue-green hues. Of course, in the western part of the Veil lies another seasonal apparition, the Witch’s Broom. via NASA http://ift.tt/1q1lTtw

Iridescent Cloud Edge Over Colorado

Sometimes your eclipse viewing goes bad in an interesting way. While watching and photographing last Thursday’s partial solar eclipse, a popular astronomy blogger suffered through long periods of clouds blocking the Sun. Unexpectedly, however, a nearby cloud began to show a rare effect: iridescence. Frequently part of a more familiar solar corona effect, iridescence is the diffraction of sunlight around a thin screen of nearly uniformly-sized water droplets. Different colors of the sunlight become deflected by slightly different angles and so come to the observer from slightly different directions. This display, featured here, was quite bright and exhibited an unusually broad range of colors. On the right, the contrails of an airplane are also visible. via NASA http://ift.tt/1tJ7ad5

Retrograde Mars

Why would Mars appear to move backwards? Most of the time, the apparent motion of Mars in Earth’s sky is in one direction, slow but steady in front of the far distant stars. About every two years, however, the Earth passes Mars as they orbit around the Sun. During the most recent such pass starting late last year, Mars as usual, loomed large and bright. Also during this time, Mars appeared to move backwards in the sky, a phenomenon called retrograde motion. Featured here is a series of images digitally stacked so that all of the stars coincide. Here, Mars appears to trace out a narrow loop in the sky. At the center of the loop, Earth passed Mars and the retrograde motion was the highest. Retrograde motion can also be seen for other Solar System planets. via NASA http://ift.tt/1DV3Du8

Plane, Clouds, Moon, Spots, Sun

What’s that in front of the Sun? The closest object is an airplane, visible just below the Sun’s center and caught purely by chance. Next out are numerous clouds in Earth’s atmosphere, creating a series of darkened horizontal streaks. Farther out is Earth’s Moon, seen as the large dark circular bite on the upper right. Just above the airplane and just below the Sun’s surface are sunspots. The main sunspot group captured here, AR 2192, is one of the largest ever recorded and has been crackling and bursting with flares since it came around the edge of the Sun early last week. Taken last Thursday, this show of solar silhouettes was unfortunately short-lived. Within a few seconds the plane flew away. Within a few minutes the clouds drifted off. Within a few hours the partial solar eclipse of the Sun by the Moon was over. Only the sunspot group remains, but within a few more days even AR 2192 will disappear around the edge of the Sun. Fortunately, when it comes to the Sun, even unexpected alignments are surprisingly frequent. via NASA http://ift.tt/1oNEuOT
