Using data from the Lunar Reconnaissance Orbiter, NASA’s Scientific Visualization Studio has produced a simulation of the side of the moon that we never get to see from Earth.
2005 cassini captures an astonishing sight, a hundred geysers shooting ice particles miles into space from cracks in the south pole. Enceladus is hurdling its guts into space at a colossal rate. As enceladus orbits saturn, these icy plumes feed a vast shimmering halo around the planet the mysterious e ring.
Moons — also called satellites — come in many shapes, sizes and types. They are generally solid bodies, and few have atmospheres. Most of the planetary moons probably formed from the discs of gas and dust circulating around planets in the early solar system. So, enjoy a range of interesting solar system moon facts.
Astronomers are moonstruck! The man in the moon, we learned just last week, formed from dark flowing lava over three billion years ago, instead of a long supposed giant asteroid impact. Now, we learn that same volcanism may have kept on erupting until surprisingly recent times.
Usually when someone on the internet writes about ‘geometric forms’ found on the Moon, it’s a crazy UFO hunter who doesn’t understand pixelation of composite images taken at high altitudes. This is different.
You may have noticed the moon looked bigger and brighter than usual this weekend. When the moon is full while its orbit is closest to Earth it’s known as a “supermoon,” creating an illusion of a dramatically large luminous sphere when viewed close to the horizon. This is what occurred over the weekend when the moon was at its fullest and still appeared brighter than normal.
Earth may have once looked a little more like Mars: a planet with two moons. It’s not the first time the theory has been trotted out by Erik Asphaug, but it’s getting new life thanks to an upcoming conference about our natural satellite. Asphaug says the second moon would have been much tinier—about 1/30th the size of our moon. But after orbiting Earth for a few million years, it would have had quite the impact, literally, on its larger twin.
The oldest rocks ever discovered in our solar system have been dated back about 4.57 billion years, meaning Earth obviously finished forming later than that. However, determining exactly when that happened can be difficult. New research presented by French geochemists from the University of Lorraine has revealed xenon isotopes. These isotopes indicate that the Earth and Moon are 60 million years older than was previously believed.
Twelve astronauts landed on the Moon between 1969 and 1972 on Apollo missions 11 through 17. They brought with them plenty of equipment essential for their survival, but they also took some rather less-expected items.
