Traces of Giant, 2,700-Year-Old Solar Storm Detected in Greenland Ice

Flares erupting on the Sun in 2014. Image: Solar Dynamics Observatory / ESA / NASA Evidence of an unusually strong solar storm that hit Earth at 660 BCE has been detected in Greenland ice cores-a finding which An extreme form of solar storm, known as a solar proton event (SPE), struck our planet 2,679 years ago, according to new research …

Climate change: Rain melts Greenland ice sheet even in winter

image copyright Joseph Cook Caption After it rains, the surface darkens, accelerating melting Rain is becoming more common in Greenland, accelerating the melting of its ice, according to a new study. Scientists say they are "surprised" when they discover a rainfall during the long Arctic winter. The huge Greenland ice sheet is being watched closely because it contains a huge …

Another huge crater was found in Greenland under the ice

A glaciologist has discovered another huge impact crater in Greenland under more than a mile of ice. This follows the discovery of a impact crater in November 2019 in the same area under the Hiawatha Glacier. The discovery in November was the first crater found on earth under ice. The two craters are only 183 km apart. The November crater …

Radar unveils a second potential impact crater among Greenland ice science

NASA SCIENTIFIC VISUALIZATION STUDIO By Paul Voosen Feb. 12, 2019, 5:30 pm Only a few months after an impact crater the size of Washington, DC buried beneath the ice of northwest Greenland has been uncovered a team of scientists discovers that it has company: a major depression 180 kilometers away This can also be an asteroid or comet impact crater. …

NASA discovers another possible impact crater buried beneath Greenland ice

Following the discovery of a massive impact crater deep below the Greenland ice sheet, scientists believe they have discovered a second, non-contiguous structure of this species nearby. The new proposed impact crater is about 22 miles (36 kilometers wide and as the first structure has not been definitively designated as impact crater.) There are many more cratered features on Earth …

"Destination Earth" – New 22-mile wide impact crater buried under Greenland ice

Posted on February 11, 2019 A NASA glaciologist has discovered a potential second impact crater buried in more than a mile of ice in northwest Greenland. This follows the November 2018 report of a 19-mile wide crater beneath the Hiawatha Glacier – the first meteorite impact crater ever discovered beneath the earth's ice sheets. Although the newly found impact locations …

NASA discovers the second crater hidden under the Greenland ice

Topography of the newly discovered Greenlandic crater. Image: NASA Goddard Space Flight Center NASA has discovered a massive, ancient crater buried beneath two kilometers of ice in northwest Greenland. Even more amazing, it is the second crater discovered in recent months under the thick ice of the region. The crater, which stretched 36.5 kilometers (22 miles), had probably been formed …

NASA detects signs of a 22-MILE WIDE crater buried under the Greenland ice sheet

Scientists have discovered what could be a 22-mile impact crater buried deep beneath Greenland's ice. If so, this would be the second discovery announced in recent months. A NASA glaciologist detects signs of a potential crater in northwest Greenland, just 114 miles from the recently discovered crater below Hiawatha Glacier, while scanning satellite imagery and topographic maps of the area. …

Greenland was WARM in Viking times, claims a new study

Researchers have long wondered how the Vikings flourished thousands of years ago in a hard and cold Greenland. But if a new study is right, the era may not have been as cold as we believe Using lake sediment cores collected in South Greenland, the researchers reconstructed the region's climate record for the past 3,000 years. The study suggests that …
