Crews from the Oman Air team (L) and Red Bull team of Austria compete during the final stage of the extreme sailing series on Sydney Harbour, December 14, 2014. Teams from 10 nations have competed in the series at eight venues around the world on 40-foot (12 metre) catamarans with the hulls flying out of the water in as little as 8 knots (15kph) of breeze.

A Red Knot (L) and a Ruddy Turnstone gather with other shorebirds to feed on Atlantic horseshoe eggs along Pickering beach, a national horseshoe crab sanctuary in Little Creek, Delaware, May 20, 2008. The Atlantic horseshoe crab, part of the Atlantic coast ecosystem and a species more than 350million years old, return from deeper water each May and June to spawn and lay their eggs on these beaches at the new and full moon tides. The eggs provide essential food for as many as one million migrating shore birds that stop here to feed on the horseshoe crab eggs as their primay food source on their northward migration.

A man uses a traditional knife to cut yarn after knots are tied as he weaves a carpet at a factory in Mashad, 950 km (590 miles) east of Tehran in this November 8, 2006 file photo. One of Iran's best-known exports, Persian carpets made from silk, wool and cotton are traditionally by women in villages, who use natural dyes derived from plants to colour them in rich hues where red, brown and cream dominate. But a half-empty hall at the annual Persian Carpet Grand Exhibition last month showed the business facing tough challenges, both at home and abroad.

Ornithologist Clive Minton from Melbourne, Australia looks for shorebirds while under attack from Strawberry flies behind the dunes in Fortescue, New Jersey, May 30, 2007. The Red Knot, a shorebird, is edging closer to extinction, threatened by fishermen who destroy its food staple for bait and loved by ornithologists who are drawn from around the world to count it. The Red Knot, once a numerous springtime visitor to the beaches of the Delaware Bay on the U.S. Atlantic Coast, has declined to an all-time low of 12,300 birds, down from some 15,000 last year and around 100,000 in the mid-1980s.

This NASA Hubble Space Telescope image of the galaxy cluster CL1358 (L) and details (R), released July 30, show a gravitationally-lensed image of a more distant galaxy located far beyond the cluster. The gravitationally-lensed image appears as a red crescent to the lower right of center, and is brightened, magnified and smeared into an arc-shape by the gravitational influence of the intervening galaxy cluster, which acts like a gigantic lens. The closeup (upper right) shows the stretched-out image revealing tiny knots of vigorous starbirth activity, and provides a first detailed look at the early construction phase of a galaxy undergoing formation. At lower right, a theoretical model of the cluster lens is used to "unsmear" the gravitationally-lensed image back into the galaxy's normal appearance. The corrected image gives a highly magnified view with detail 5-10 times smaller than the Hubble alone can provide. The original image was taken with Hubble's Wide Field Planetary Camera 2 on January 13 1996.
