A few days ago NASA’s IceBridge project hit the news, but not for any scientific observations. Instead, a photo of a strange rectangular iceberg captured people’s imagination. Now, NASA has offered up a few more shots of this unusual sight, helping explain this common yet rarely seen phenomenon.

NASA's Operation IceBridge is currently gathering measurements of Antarctic land and sea ice. The data it gathers will be compared to measurements from the newly orbiting ICESat-2, while the images captured provide a breathtaking look in and around the frozen continent.

After monitoring seismic activity over a few years, researchers noticed that the Ross Ice Shelf in Antarctica is “singing” – and listening out for changes in that song could be an early warning system for potential problems.

While NASA has plans to possibly send a lander to Europa in the coming years, a new discovery might make touchdown tricky – there’s a chance that large swathes of Europa’s surface are covered in ice spikes almost 50 ft (15 m) high.

In order to keep ice from forming on surfaces such as airplane wings, toxic chemicals are typically applied. And while there are experimental chemical-free alternatives, they still require a power source or involve coatings that can wear off. A new system, however, gets around those issues.

Researchers at MIT have come up with a de-icing system that is completely passive and relies only on the power of the sun, or artificial light, which means it can also work at night. The system could be used to prevent ice building up on aircraft wings, wind turbine blades, and powerlines.

NASA is preparing to launch a new tool into orbit that will bounce lasers off polar ice to finely monitor elevation changes over time, providing new insights into not only the severity of climate change, but how it is directly impacting seal level rise.

Freezing is one of the simplest methods of preserving food, biological tissue and other perishables, but the formation of ice crystals can damage cells. Now, researchers have developed a new way to “supercool” water in a liquid form well below the usual freezing point.

A huge lake of liquid water has been found on Mars. The groundbreaking discovery marks the first time a significant amount of the life-giving liquid has been detected. Discovered through satellite radar readings, the lake lies beneath the ice caps at the south pole of Mars.

The International Chronostratigraphic Chart has officially been revised. That means our current point in Earth’s geological timeline has been updated so that we’re now living in the Meghalayan age, which began 4,200 years ago with a two-century drought that destroyed several civilizations.
