This Picture of the Moon Is the First Photo Taken By A New 3-D Printed Telescope

3-D printing technology has been improving in leaps and bounds lately, and now it can add yet another cool accomplishment to its resumé: taking a picture of the moon. It all started with a team of astronomers at the University of Sheffield in England who wanted to see if they could design their own high-powered telescope rather than paying thousands of dollars for one. Using only 3-D printer and a Raspberry Pi camera module, the team was able to create a telescope capable

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

The Strongest and Most Misunderstood Creature in the World (Video)

When you think of strength in the animal kingdom, it’s natural to think of some of the massive majestic creatures we’re all so familiar with: lions, elephant, grizzlies, rhinos, hippos… These animals are definitely powerful, but when you examine pound-for-pound strength, you quickly realize that it’s the smallest creatures who are really the most impressive lifters. Take the leafcutter ant, for instance. These ants cut off and carry leaf segments that are sometimes up to 50 times heavier than they are.

NASA’s Opportunity Rover Just Set the Off-World Driving Distance Record

NASA’s Opportunity rover landed on the surface of Mars in January of 2004. As of Sunday (July 26), the Opportunity rover had driven a total distance of 25 miles (40 kilometers). Opportunity took the top spot in total off-world distance traveled by surpassing Russia’s Lunokhod 2 lunar rover, which traveled a total distance of 39 kilometers across the surface of the moon between January and May of 1973. The Russian rover helped to bring about a golden age of space exploration in the

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

A Few Reasons Why Tomorrow Might Be A Bit of a Strange Day…

Tomorrow will not be your ordinary Friday. For starters, tomorrow is the 13th, making tomorrow a Friday the 13th. There will also be a full moon in the sky when the clock strikes 12:01 a.m. tomorrow morning. The last time that happened? October 13, 2000. The next time it will happen? August 13, 2049. I’m not one for superstitions, but there is one thing I haven’t mentioned yet. Our sun has been shooting off powerful solar flares the last few days, including this one captured

Watch A Four-Year Timelapse of A Mysterious Cosmic Explosion Captured By the Hubble Telescope (Video)

Back in January of 2002, astronomers witnessed a huge explosion from the star V838 Monocerotis, a red variable star about 20,000 light years away from our Sun. At first, they thought it was a typical supernova (the explosion of a dying star), but after watching the explosion dim then brighten twice over a period of only a few months (supernovas will usually only dim after the initial bright explosion), astronomers really weren’t sure what they were dealing with. Check out a time-lapse of the

NASA Made an Amazing Mosaic of Earth Using Over 36,000 Selfies Taken All Across the Globe

Last month, NASA set out to create a “global selfie”. First, they asked people around the world to take pictures of themselves with a little NASA placard saying where they were. They then compiled the 36,422 selfies they got into a stunningly accurate mosaic of the Earth. For Earth Day (April 22), NASA used social media to pose the question, “Where are you on Earth right now?”, encouraging fans and followers to take selfies and post them using the hashtag #GlobalSelfie. Selfies were

How to Watch the First Ever Camelopardalid Meteor Shower Tonight (Live Stream)

Starting at around 11 p.m. Eastern time tonight, the Camelopardalid Meteor Shower will be peaking in the night sky. The meteors are the debris left behind by the comet P/209 LINEAR almost two centuries ago. On May 23/24, Earth will be passing through this trail of debris, which is why the meteors will be visible to us here on Earth tonight for the first time ever. The comets will appear to be coming from the constellation Ursa Major (the Big Dipper). Astronomers are

What It Looks Like When Two Neutron Stars Rip Each Other Apart to Form a Black Hole (Video)

A neutron star is what’s left behind when a massive star (typically 8-30 times the size of our Sun) explodes into a supernova. These supergiant stars get so large that they are no longer able to remain stable under their own intense gravity, collapsing in on themselves. The gravity is so massive that it exceeds the strength of the atomic forces within particles, causing them to eject protons and electrons. The ball of neutrons they leave behind is so dense that a
