Imagine a pivotal scene from your favorite sci-fi alien invasion movie where their 50-foot wide laser beams destroy our buildings like sneezing on a pile of flour. What could we do? We’re merely meat muppets with pitiful silicon based technology. How could we ever hope to detect these aliens with their stealth spacecraft and 3rd stage guild navigators? If we’re […]

Mysterious radio signals from space have been known to repeat, but for the first time, researchers have noticed a pattern in a series of bursts coming from a single source half a billion light-years from Earth. Fast radio bursts, or FRBs, are millisecond-long bursts of radio waves in space. Individual radio bursts emit once and don’t repeat. But repeating fast […]

With temperatures in excess of 800 F, Mercury is one of the last places in the solar system you’d expect to find ice. But when NASA’s Messenger spacecraft transmitted its first optical images of the closest planets to the sun, that’s exactly what scientists discovered. Mercury sits about 36 million miles from the sun, which is roughly 57 million miles […]

On the 35th anniversary of its launch, the Voyager 1 spacecraft is close to becoming the first man-made object to escape our solar system. The spacecraft—run by a 1977 computer 100,000 times less powerful than an iPod Nano—is currently 11.3 billion miles away. In 2004, Voyager 1 entered the turbulent boundary zone beyond Pluto, where solar winds encounter plasma pushing […]

The most common Visitors from outer space… COMETS!! Near misses by comets and asteroids are rare events, but in 2013, predictions were made that earthlings would experience at least three. A menacing, 1,000-foot-wide asteroid named Apophis which passed within 9 million miles of our planet—close by astronomical standards. Dubbed “the doomsday asteroid,” Apophis has an elliptical orbit around the sun […]

The evidence for a new geological epoch which marks the impact of human activity on Earth is now overwhelming according to a recent paper by an international group of geo-scientists. The Anthropocene, which is argued to start in the mid-20th Century, is marked by the spread of materials such as aluminum, concrete, plastic, fly ash and fallout from nuclear testing […]

The stage has been set for a new space race between China and the US. China has sent a lunar lander to the dark side of the moon. Since communication is not feasible from the dark side the Chinese had to send a relay satellite up in a specific location so that they can transmit information from the craft and […]

Scientists typically believe that dark matter behaves in a simple way: if one clump encounters another, the two interact solely through gravity. However, researchers have published findings which suggest that there’s more involved. They’ve noticed dark matter (the blue lines in the photo above) lagging behind a galaxy due to friction, hinting that there are factors beyond gravity at work. […]

People always wonder how the moon was made. The birth of the planets 4.5 billion years ago was extremely violent. They grew to full size by absorbing rival planet embryos in a series of titanic collisions—one of which probably gave Earth its moon (below). The moon’s large size, low density, and other features suggest that it emerged from an explosion […]
