The Antarctic is being melted from below, according to a new study by Nasa - and a type of buried super-volcano may be to blame. The Nasa study adds evidence that there is powerful geothermal activity underneath the ice, creating lakes and rivers below the surface.4 comments
A massive rift in the Antarctica has been spotted by NASA, but the troubling details about the rift is causing the agency to worry. The ice shelf in Larsen C that is close to breaking off is as big as the size of the state of Delaware.
This month's bright supermoon — the closest full moon in 68 years — is expected to light up the sky early Monday morning, NASA has reported. Every year, scientists and sky watchers welcome the supermoon, which is the closest full moon of the year. But this year, the supermoon is receiving extraordinary attention.
The growth of Arctic sea ice this winter recorded the lowest maximum level on record, prompting fears of faster climate change than previously expected. Unusually warm temperatures were said to be responsible for the shrinkage.
2015 was by far the hottest year in modern times and raising new concerns about the accelerating pace of climate change. Not only was 2015 the warmest worldwide since 1880, it shattered the previous record held in 2014 by the widest margin ever observed, said the report by the National Oceanic and Atmospheric Administration.
In a new twist to the old song, it’s Santa Claus who had “better watch out” on Christmas Eve, as he shares the night sky with a huge asteroid that will make its closest pass to Earth at about the same time the jolly old fellow is making his annual deliveries.
The globally averaged temperature over land and ocean surfaces for March 2015 was the highest for the month since record keeping began in 1880. The year-to-date (January–March) globally averaged temperature was also record high, reports the US National Oceanographic and Atmospheric Administration, together with data from NASA.
The Antarctic ozone hole reached its annual peak size on Sept. 11, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). The size of this year’s hole was 24.1 million square kilometers, an area roughly the size of North America.
NASA has lately spotted a gigantic iceberg in Antarctica, identified as B31 and together with UK's BAS (British Antarctic Survey), is busy tracking the monster island of ice, which has now escaped into open waters. Despite its sheer size and mass, --experts estimate that the giant iceberg is approximately 600 square kilometres in size--, monitoring is not going to be an easy task with the coming of the Antarctic winter and ensuing darkness.
Argentine space expert Jorge Coghlan said that the huge bang heard on Tuesday and that scared many people in central Santa Fe province was caused by a meteorite which disintegrated on entering the atmosphere and thus caused a major vibration. The incident was reported early mid morning.
