NASA scientists completed field tests in November of a floating rover they hope will one day travel to Europa, the frozen ocean moon of Jupiter.

It’s been nearly 350 years since Sir Isaac Newton outlined the laws of motion, claiming “For every action, there is an equal and opposite reaction.” These laws laid the foundation to understand our solar system and, more broadly, to understand the relationship between a body of mass and the forces that act upon it. However, Newton’s groundbreaking work also created a pickle that has baffled scientists for centuries: The Three-Body Problem.
After using the laws of motion to describe how planet Earth orbits the sun, Newton assumed that these laws would help us calculate what would happen if a third celestial body, such as the moon, were added to the mix. However, in reality, three-body equations became much more difficult to solve.

Steven L. Kwast is a retired Air Force general and former commander of the Air Education and Training Command at Joint Base San Antonio-Randolph. A graduate of the United States Air Force Academy with a degree in astronautical engineering, he holds a master’s degree in public policy from Harvard’s Kennedy School of Government. He is a past president of the Air Force’s Air University in Montgomery, Alabama, and a former fighter pilot with extensive combat and command experience. He is the author of the study, “Fast Space: Leveraging Ultra Low-Cost Space Access for 21st Century Challenges.”
Beginning in 2010, and coinciding with the opening of Hillsdale College’s Allan P. Kirby, Jr. Center for Constitutional Studies and Citizenship on Capitol Hill, the College has hosted an annual Constitution Day Celebration in Washington, D.C. to commemorate the signing of the U.S. Constitution on September 17, 1787.
Russia’s Skolkovo innovation center, which is marking 10 years since its founding, has ambitious plans for 2020 and beyond to continue promoting technology and helping small innovative startups grow into profitable companies.
Skolkovo Technopark was built from scratch almost a decade ago to create a platform for research and innovation in key spheres such as energy, IT, space, biomedicine, and nuclear technology. Now the complex has facilities spread around 800,000 square meters and hosts around 500 startups, while there are an additional 1,500 enterprises beyond its campus. Skolkovo hosts around 50 research centers employing more than 15,000 people.
Researchers at Columbia University and University of California, San Diego, have introduced a novel “multi-messenger” approach to quantum physics that signifies a technological leap in how scientists can explore quantum materials.
The findings appear in a recent article published in Nature Materials, led by A. S. McLeod, postdoctoral researcher, Columbia Nano Initiative, with co-authors Dmitri Basov and A. J. Millis at Columbia and R.A. Averitt at UC San Diego.
“We have brought a technique from the inter-galactic scale down to the realm of the ultra-small,” said Basov, Higgins Professor of Physics and Director of the Energy Frontier Research Center at Columbia. Equipped with multi-modal nanoscience tools we can now routinely go places no one thought would be possible as recently as five years ago.”

No one really knows what happens inside an atom. But two competing groups of scientists think they’ve figured it out. And both are racing to prove that their own vision is correct.
Here’s what we know for sure: Electrons whiz around “orbitals” in an atom’s outer shell. Then there’s a whole lot of empty space. And then, right in the center of that space, there’s a tiny nucleus — a dense knot of protons and neutrons that give the atom most of its mass. Those protons and neutrons cluster together, bound by what’s called the strong force. And the numbers of those protons and neutrons determine whether the atom is iron or oxygen or xenon, and whether it’s radioactive or stable.
Breakthroughs include measuring the true nature of the universe, finding new species of human ancestors, and unlocking new ways to fight disease.
What can you see in the night sky this month? The peak of the Quadrantid meteor shower, Mars rises with its “rival” — the red giant star Antares — and the Moon and Venus pair up.
