It's always interesting when meteors streaked through the atmosphere of the earth creating fiery trails that those of us on Earth can see with the naked eye. These fireballs are relatively rare since most go unseen. However, this week a spectacular fireball was recorded over the American South East and briefly it shine brighter than the moon.
One of the key chemical ingredients scientists believe to be required for life is phosphate. Phosphate is plentiful here on Earth, but scientists now believe that phosphate could've been more abundant on ancient Mars that it is on earth today. Phosphate is believed to be a required component for life because it is the backbone of DNA and an essential part of molecules that cells use to generate energy and their required membranes.
Data NASA provided to scientists from an airborne science mission has revealed the existence of a massive canyon in Greenland that has been hidden for the entirety of human history on the Earth. According to the scientists, the canyon has the characteristics of a winding river channel and is at least 460 miles long. That means it's longer than the Grand Canyon.
One year ago (and two days), the family of Neil Armstrong announced that this navy fighter pilot, test pilot, and astronaut passed away at the age of 82. Making known that Armstrong was a "reluctant American hero", his family said that he "always believed he was just doing his job." Neil Armstrong became the first human being to step foot on the moon on July 20th, 1969, followed 20 minutes afterward by his crewmate Buzz Aldrin. MAKE SURE you have a look at the update at the end of this article - Armstrong didn't die twice!
SpaceX's Grasshopper test rig for the Falcon 9 reusable launch vehicle has stepped up its game, with Elon Musk's private space company demonstrating that the rocket can now not only take off and land in a straight line, but track sideways as part of the maneuver. A vital talent if Grasshopper is to land safely when put into full service, the so-called divert test saw the 106-foot rocket flying to 250m while also completing a 100m lateral shift.
NASA's Curiosity rover is currently putzing around on the surface of Mars, and we've seen plenty of pictures to know what the red planet looks like. However, a new simulator that NASA put together using an Oculus Rift VR headset and a Virtuix Omni VR treadmill, you'll now be able to know what it's like to walk around on Mars.
In the latest of 3D-printed hardware, NASA has completed a series of test firings of the agency's first rocket engine part made entirely from 3D printing. The component in question is the rocket engine's injector, and it went through several hot-fire tests using a mix of liquid-oxygen and gaseous hydrogen.
NASA's Hubble space telescope has identified the true color of a planet 63 light years away from Earth, a distant blue marble that, unlike our own planet, has torrential rainstorms of glass. HD 189733b, orbiting star HD 189733, would be seen by human eyes as a striking cobalt blue, the Hubble team says, ostensibly similar to Earth when viewed from space. However, in actual fact the exoplanet is one of a bizarre collection of "hot Jupiters" where temperatures can reach almost 2,000 degrees Fahrenheit (over 1,000 degrees Celcius).
Many stunning objects in our solar system have tails. We see them most often in comets, meteoroids, asteroids, etc. Tails are formed when dust and ice on these objects burn up as they heat up, which results in debris letting loose and leaving a trail behind the comet. As it turns out, even our own solar system has a tail.
