Fly Me to the Moon is an upcoming American romantic comedy-drama film directed by Greg Berlanti and written by Rose Gilroy. The film stars Scarlett Johansson, Channing Tatum, Nick Dillenburg, Anna Garcia, Jim Rash, Noah Robbins, Colin Woodell, Christian Zuber, Donald Elise Watkins, Ray Romano, and Woody Harrelson. Its plot follows the relationship between a marketing specialist and a NASA director during the 1960s Space Race.

The radiation belts around Earth are loaded with dangerous protons and electrons that can damage spacecraft. Now researchers are launching experiments to see if they can clear away the high-energy particles that pose the hazard by blasting them with radio waves.When humans began exploring space, the first major find was the Van Allen radiation belts, doughnut-shaped zones of magnetically trapped, highly energetic charged particles. The Van Allen belts consist mainly of two rings: The inner belt starts roughly 1000 kilometers above Earth’s surface and extends up to 9600 km, while the outer belt stretches from about 13 500 to 58...

Using NASA’s Van Allen Probes, new research reveals that the Van Allen radiation belts contain a nearly impenetrable barrier that prevents the fastest, most energetic electrons from reaching Earth.The Van Allen belts are a collection of charged particles, gathered in place by Earth’s magnetic field. They can wax and wane in response to incoming energy from the sun, sometimes swelling up enough to expose satellites in low-Earth orbit to damaging radiation. The discovery of the drain that acts as a barrier within the belts was made using NASA’s Van Allen Probes, launched in August 2012 to study the region. A...

NASA's new Imaging X-Ray Polarimetry Explorer spacecraft is a tiny satellite with the unique ability to capture images in X-ray with polarization and timing information for every photon captured. It's designed to operate for 2 years and capture new scientific measurements of some of the most extreme places in the universe with gravitational and magnetic fields that would destroy ordinary matter.And in an interesting turn of events the satellite switched from the intended launch vehicle to a cheaper option that nobody considered - the Falcon 9. This is the first time we've seen a rocket lauched from a domestic US...

How Fast Is Earth Moving? As an Earthling, it's easy to believe that we're standing still. After all, we don't feel any movement in our surroundings. But when you look at the sky, you can see evidence that we are moving. Some of the earliest astronomers proposed that we live in a geocentric universe, which means that Earth is at the center of everything. They said the sun rotated around us, which caused sunrises and sunsets — same for the movements of the moon and the planets. But there were certain things that didn't work with this vision. Sometimes, a...

A team led by the University of Colorado Boulder has discovered an invisible shield some 7,200 miles above Earth that blocks so-called “killer electrons,” which whip around the planet at near-light speed and have been known to threaten astronauts, fry satellites and degrade space systems during intense solar storms. The barrier to the particle motion was discovered in the Van Allen radiation belts, two doughnut-shaped rings above Earth that are filled with high-energy electrons and protons, said Distinguished Professor Daniel Baker, director of CU-Boulder’s Laboratory for Atmospheric and Space Physics (LASP). ... The latest mystery revolves around an “extremely sharp”...

Van Allen belts accelerate their own particles rather than just trapping them. The two concentric rings of high-speed particles that encircle the Earth are finally giving up the secrets of their origin — 55 years after their discovery. Two NASA probes have found evidence that the Van Allen belts, as the rings are known, are responsible for accelerating the particles, rather than collecting energetic particles that originated elsewhere. Space scientists think that their latest findings1 could also account for the even more energetic belts circling Saturn and Jupiter, as well as high-energy radiation associated with worlds beyond the Solar System...
