It feels instantaneous, but how long does it really take to think a thought?
A new study from the astounding Cassini mission suggests that Saturn’s large moon Titan may undergo geological processes similar to those that create sinkholes on Earth. The study might answer the mystery of how Titan – known to be home to seas and lakes filled with liquid hydrocarbons – came to have depressions on its surface into which those liquids can gather.
Mount Sinabung in Indonesia was once considered a dormant volcano, until it erupted for a brief one month period in 2010. Then, on September 15, 2013, it began erupting again and the volcanic activity has continued until today.
Understanding why volcanoes come out of dormancy is no easy task for scientists, but a paper published last year in Solid Earth suggests that some of the recent megathrust earthquakes in Sumatra could be to blame.
In recent years, astronomers have become increasingly certain that planets are common in our Milky Way galaxy. And it’s possible that most stars have planets in their habitable zones, an area around stars within which liquid water – and therefore life as we know it – can exist. How many of those worlds are inhabited by simple or complex life forms? And when will we on Earth discover alien life? Follow the links inside to learn more.

Most of us think only of viewing planets at night, but sometimes you can catch them in broad daylight! The next great chance to do that is Saturday, June 20.
Tropical Storm Bill, the second named storm of the 2015 Atlantic hurricane season, made landfall along the Texas coast on Matagorda Island – between Houston and Corpus Christi – on Tuesday at 11:45 a.m. CDT (1645 UTC). Top speeds for sustained winds was 60 mph (100 kph). Bill had formed in the western Gulf of Mexico with 50 mile per hour (80 kph) sustained winds. While most people focus on wind speeds and names of storms, the biggest impact from Bill will likely be the heavy rain and flooding potential. Flash flooding was expected in several spots across Texas Tuesday and the threat is now spreading northwards into Oklahoma, Arkansas and Missouri for Wednesday, June 17, 2015.
NASA astronomers using the Chandra X-ray Observatory probe have discovered a unique group of galaxies that appear to have undergone substantial restructuring due to multiple eruptions from a supermassive black hole. The eruptions took place over 50 million years, astronomers say. These eruptive bursts of energy caused shockwaves and pushed surrounding gas in the galaxy cluster away from the black hole’s center, causing visible cavities much like giant bubbles.
Geologists in China announced this week that the deadly magnitude-7.9 earthquake in Nepal on April 25 moved Mount Everest by 3 centimeters to the southwest. The quake – one of two large earthquakes to occur in Nepal this spring – left more than 8,700 people dead. China Daily reported on the findings of these geologists earlier today. China’s National Administration of Surveying, Mapping and Geoinformation published the geologists’ report on Monday.
