NASA released amazing close-up images of the giant new iceberg in AntarcticaNathaniel LeeJessica Orwig
Would you go to the end of the world to see a total eclipse of the Sun? If you did, would you be surprised to find someone else there already? In 2003, the Sun, the Moon, Antarctica, and two photographers all lined up in Antarctica during an unusual total solar eclipse. Even given...
In January 2019, NASA captured an image of Antarctica’s Brunt Ice Shelf as it neared a substantial break that will release an iceberg twice the size of New York City. The crack, at the top right of the image, is called the “Halloween crack,” as it first appeared in October 2016. ...
A vivid aurora streams over the Earth as theInternational Space Stationorbits 274 miles above the southern Indian Ocean in between Australia and Antarctica. The station orbits the Earth in about 90 minutes. In 24 hours, the space station makes 16 orbits of Earth, traveling through 16 sunri...
Antarctica is supposed to be an extremely cold place. The annual mean temperature of the snow-laden continent's central area is -57 degrees Celsius (−70.6°F); even the coast averages around -10°C (14°F). 南极应该是极寒之地,这个冰雪覆盖的大陆的中心地带年平均温度是-57摄氏度(−70....
Using data from the original ICESat in 2007, Fricker found for the first time that under Antarctica’s fast flowing ice streams, an entire network of lakes connect with one another, filling and draining actively over time. Before, these lakes were thought to hold meltwater statically, without...
The findings published recently unlocked the secrets about the species that can provide an early-warning of threats to Antarctica’s delicate ecosystem. Researchers from Stony Brook University used satellite images to see if the Adelie penguin’s diet has been changing in response to Antarctica’s ...
Astronomers can think of two ways in which a dense cloud of dust is prevented from further contracting into a star: turbulence in the dust, or the collapse-impeding effects of magnetic fields. On its new mission, BLAST should find out which process is to blame.[Images: Life at Antarctica'...

The Antarctic waters are the closest Earth analog to the seas of an icy moon, which makes them an ideal testing ground for BRUIE technology, said the JPL. The buoyant rover, one meter long and equipped with two wheels to roll along beneath the ice, can take images and collect data on ...
