A vast ocean probably covered a third of the surface of Mars about 3.5 billion years ago, according to a new study by scientists at the University of Colorado. The study is the first to combine the analysis of river deltas and valleys to detect the presence of an ocean supported by a global hydrosphere on ancient Mars.
Did you know that raindrops are not shaped like a teardrop? And that it takes 7,000 liters of water to refine a barrel of crude oil? Quench your thirst for knowledge in this selection of curious facts about water that we have prepared.
NASA's 'Mini-SAR' radar, installed on the Indian satellite Chandrayaan-1, has detected more than 40 small lunar craters 1.6 to 15 kilometers in size, all filled with ice. "Although the total amount of ice depends on its thickness in each crater, it is estimated that there could be at least 600 million metric tons of frozen water on the satellite," NASA said in a statement.
A couple of engineers from Cornell University, in the United States, have developed a small device called SECAD that uses the surface tension of water to adhere strongly to any surface. The new ingenuity, they predict, will allow us to walk on the walls and ceilings emulating Spiderman himself.
There is water on the Moon. This is the conclusion reached by the authors of three different scientific studies published today in the journal Science. A fourth study reveals that there is ice on Mars under five craters created by the impact of meteorites.
When raindrops hit the ground they do so in a wide variety of sizes. A study with high-speed cameras carried out at the Aix-Marseille University in Marseille (France) has revealed the physical process behind this diversity.
One of the greatest summer pleasures is quenching the heat with a good beer, the alcoholic beverage that quenches thirst the most. This is because its main component is water, which represents 93% of the total weight of the product. Undoubtedly, the temperature at which it should be served: between 6 and 8 ºC also promotes the sensation of freshness.
