Seven sovereign states had made eight territorial claims to land in Antarctica below the 60° S parallel before 1961. These claims have been recognized only between the countries making claims in the area. All claim areas are sectors, with the exception of Peter I Island. None of these claims has an indigenous population. The South Orkney Islands fall within the territory claimed by Argentina and United Kingdom; and the South Shetland Islands fall within the areas claimed by Argentina, Chile, and the United Kingdom. The UK, France, Australia, New Zealand and Norway all recognize each others' claims,[#] which do not overlap. Prior to 1962, British Antarctic Territory was a dependency of the Falkland Islands and also included South Georgia and the South Sandwich Islands. The Antarctic areas became a separate overseas territory following the ratification of the Antarctic Treaty. South Georgia and the South Sandwich Islands remained a dependency of the Falkland Islands until 1985 when they too became a separate overseas territory. 


Signs of the eruption at Mount Merapi managed to puncture the persistent cloud cover over Java on November 5, 2010. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image the same day.
The volcano’s plume formed a V shape, fanning out to the west from the summit and casting shadows on the surrounding clouds below. According to the Volcanic Ash Advisory Center in Darwin, Australia, the ash plume rose to at least 55,000 feet (16 kilometers) in altitude and stretched 220 miles (350 km) to the west and southwest, as of 12:13 a.m. local time on November 6 (17:13 UTC, Nov 5).
The Eruptions volcanism blog and the Associated Press reported a death toll of at least 122 people, more than 100,000 people evacuated, and homes and fields covered in volcanic ash. The Indonesian government declared the event a national emergency and extended the “danger zone” for the eruption to 12 miles (20 kilometers), including the ancient capital of Yogyakarta.
Among Indonesia’s most active volcanoes, Merapi sits in one of the world’s most densely populated areas. Recorded eruptions have included multiple pyroclastic flows—searing avalanches of ash, gas, and rock fragments—and lahars—flows of water, rock debris, and mud caused by rainwater mixing with ash and other volcanic material. These eruptions have repeatedly devastated nearby communities and croplands.

The "boot" of Italy glitters with nighttime lights, as seen from 220 miles (354 kilometers) above Earth on the International Space Station (ISS) last week. Part of a docked Russian spacecraft is also visible in the foreground.
On Tuesday NASA officials celebrated the ten-year anniversary of people living on the ISS. NASA astronaut Bill Shepherd and Russian cosmonauts Yuri Gidzenko and Sergei Krikalev were the first crew members to call the station home, spending just over 136 days on board in 2000.
Since then rotating crews have kept the orbiting lab occupied around the clock, every day of the year, for the past decade.
