Dunes of sand sweep across the solar system, building drifts on any world with even the slightest hint of a breeze. Some look like the features we’re familiar with on Earth, made up of bits of rock or ice, while some appear far more alien, built solely from organic material.
On Earth, sand is commonly built by eroding quartz. But it can also comprise shells, coral, carbonate, volcanic ash, and even ice. That means sand can develop and settle not only in beaches and deserts but also in the frozen barrens of Antarctica.
Frankfurt Airport to build 13-MWp solar system along runway
October 11 (Renewables Now) - Airport operator Fraport AG (ETR:FRA) will install a 13-MWp solar photovoltaic (PV) system along a runway at the Frankfurt Airport as Germany's busiest airport is seeking to raise its share of green energy.
A demonstration triple-array system of 20 PV panels with an output of 8.4 kW has been already set up at the southwestern end of Runway 18 West and will be extended along the runway to reach a length of 2,600 m (2,843 yd), Fraport said in a press statement.
Video shows devastation if biggest asteroid in the Solar System collided with Earth - Scottish ...
Many took to social media to share what they thought about the fascinating video. One reassured: "Fortunately, the massive gravity well of Jupiter steers most objects away from our orbit."
Someone else chimed: "Looks like I'd need to hunker down in my basement for a day or two until this thing blows over."
NASA Study Suggests Shallow Lakes in Europa's Icy Crust Could Erupt
New research makes hypotheses that NASA's Europa Clipper can test: Any plumes or volcanic activity at the Jovian moon's surface are caused by shallow lakes in its icy crust.
This illustration depicts a plume of water vapor that could potentially be emitted from the icy surface of Jupiter's moon Europa. New research sheds light on what plumes, if they do exist, could reveal about lakes that may be inside the moon's crust.

Zap. A muscle in her chest twitched. Zap. And again. Marie Moe could feel it. She could even see it. She looked down and the muscle, just to the left of her breastbone, was visibly pulsating. Convulsing with the rhythm of a vigorous heartbeat.
The cyber-security researcher was on a plane, about 20 minutes from its destination, Amsterdam, when it started. Fear gripped her. She knew immediately that something was wrong with her pacemaker, the small medical device implanted in her chest that used electrical impulses to steady her ...
Secrets to The Moon's Slow Escape Have Been Uncovered in Earth's Crust : ScienceAlert
If we take the Moon's current rate of recession and project it back in time, we end up with a collision between the Earth and Moon around 1.5 billion years ago . However, the Moon was formed around 4.5 billion years ago , meaning that the current recession rate is a poor guide for the past.
