New Photo of Europa Shows the Ice-Covered Moon’s Surface in Stunning Detail (Video)

NASA’s Galileo spacecraft has been orbiting Jupiter since the late 1990’s. Since then, NASA has recorded data, producing stellar imaging of one of Jupiter’s largest moons, Europa. Thanks to many years of observation, astronomers have garnered enough data to depict the Jovian moon (Jovian refers to anything related to Jupiter) in its fullest, most breathtaking form yet! NASA added the photo to its extensive Photo Journal on November 21st. Innovations in optical technology have allowed astronomers to observe Europa in much

This Mobile Solar Generator Can Provide Power, Clean Water and Wi-Fi to Disaster Areas


When disaster strikes, securing access to power, clean drinking water and the communications network are all integral parts of the initial response. That’s why the Ecos PowerCube is such an intriguing invention. The PowerCube’s designers – a company called Ecosphere Technologies – wanted to build a device that could provide significant amounts of off-the-grid power during disasters. The power is generated using solar panels equipped with high-power photovoltaic cells (the Cube is also equipped with a wind turbine for extra power generation). The largest

Watch Snowflakes Form Right Before Your Eyes In This Enchanting Time-Lapse Video

If you went to elementary school in the United States, it’s pretty likely that you made a paper cut-out snowflake at some point. As a kid, these elaborate craft projects didn’t really seem to resemble real snowflakes – until you actually see a real snowflake up close, that is. To the naked eye they may look like little puffs of white powder, but snowflakes actually have very complex and intricate crystalline patterns, a result of the way in which they are formed. As cold

Moon Mining: NASA’s Plans to Harvest Water from the Moon

There’s a lot of water on the moon, and NASA wants to learn how to get to it. In July 2008, water was found conclusively for the first time inside ancient moon samples brought back by Apollo astronauts. In 2009, observations from three spacecraft showed signals of water across the moon’s surface, bolstering the idea that the moon might actually contain significant amount of water. Then, in October 2010, scientists reported that a frigid crater called Cabeus at the moon’s south pole is

Water Wars: How ISIS Is Using Water As A Weapon of Control

Editor’s note: The Higher Learning is excited to announce that we have acquired another talented new author! Max Wingert is a recent graduate of the University of Arizona, where he received a degree in Communications (with a minor in Japanese). He wrote the following article. The group known as the Islamic State of Iraq and Syria (ISIS) has proven to be a more sophisticated enemy than terrorist groups of the past, fighting to seize infrastructure and resources for the purposes of population control and extortion, rather

Pictures That Show You Just How Extreme California’s Current Drought Is

If you weren’t aware, California is going through a very serious drought. 2013 saw the lowest rainfall numbers in California’s recorded history, and 2014 has been by far the hottest year on record for the state, according to the NOAA. The Palmer Drought Severity Index (PDSI) is a standardized metric which compares long-term droughts by looking at rainfall, temperature and soil moisture levels. The scale goes from +6 (very wet), to -6 (very dry). Anything below a -4 is considered

Why Ultra-Pure Water Is Actually Bad for Your Health (Video)

We tend to imagine that purity is the ultimate indicator of the quality of water. So why is 100%, ultra-pure water not good for us? Well the simple answer is that water (H20) purely comprised of hydrogen and oxygen doesn’t provide our body with the natural electrolytes and salts we need to survive. There is no such thing as truly pure water in the natural world. Even water in the purest springs and lakes contains small amounts of dissolved minerals such as sodium, chloride,

What Mars Looked Like When It Had Water, Courtesy of NASA (Video)

Today, we think of Mars as having  a cold, dry, and desolate environment (because it does). But that was not always the case. Four billion years ago, while our Sun was still in its infancy, Mars was covered with water. Back then, it had a much thicker atmosphere, which kept the planet warm enough for water to exist in its liquid form. Some estimates say that at one point, up to 1640 ft (about half a kilometer) of water covered the

A Mysterious Lake Just Suddenly Appeared in the Middle of the Desert in Tunisia

Apparently, Siberia isn’t the only place that has been experiencing strange geological occurrences lately. Residents of the Gafsa region in Tunisia are still trying to make sense of a lake that appeared out of nowhere recently. A group of three shepherds with an intimate knowledge of the land in the region discovered the new lake three weeks ago. Since then, people in the area have been buzzing. Some people say it’s a miracle- others say it’s a curse. Tunisian authorities have officially

NASA Is Seeking Help In Potentially Finding Life On Jupiter’s Moon Europa (Video)

NASA is confident that underneath Jupiter’s moon Europa there could be more water than in our oceans here on Earth. So naturally, Europa has attracted a lot of attention, encouraging the curious to ask, “Could there be life on Europa?”. Currently, NASA is aiming to send a new mission to Europa by 2025. The White House’s 2015 federal budget allocates $15 million towards making this Europa mission a reality. Europa has recently become one of NASA’s main focuses because,  out of all the
