Materials scientists at Duke University have shown the first clear example that a material’s transition into a magnet can control instabilities in its crystalline structure that cause it to change from a conductor to an insulator.
If researchers can learn to control this unique connection between physical properties identified in hexagonal iron sulfide, it could enable new technologies such as spintronic computing. The results appear April 13 in the journal Nature Physics.
Commonly known as troilite, hexagonal iron sulfide can be found natively on Earth but is more abundant in meteorites, particularly those originating from the Moon and Mars. Rarely encountered in the Earth’s crust, most troilite on Earth is believed to have originated from space.
Designer Michal Bonikowski’s concept is probably four or five generations ahead of the current mode of thinking, but Bonikowski told Robb Report that he was inspired by the recent Maveric concept by Airbus. “That aircraft’s unique design helps reduce drag while providing more cabin space,” he said. “I have been thinking a lot about this lately, and wondered what could happen if a big company would like to create an electric plane.”

There’s an iconic scene in the original Star Wars movie where Luke Skywalker looks out over the desert landscape of Tatooine at the amazing spectacle of a double sunset.
Now, a new study out of the National Radio Astronomy Observatory (NRAO) suggests that such exotic exoplanet worlds orbiting multiple stars may exist in misaligned orbits, far out of the primary orbital plane.
The find has implications for planetary formation in complex multiple star systems. The study used ALMA (the Atacama Large Millimeter/submillimeter Array) in Chile to look at 19 protoplanetary disks around binary stars with longer period orbits, versus a dozen binary stars known to host exoplanets with periods less than 40 days found in the Kepler space telescope observations.
Space can be a horror show of cosmic violence, and now astronomers have captured the first photographic evidence of the carnage that can be unleashed when two heavyweight galaxies collide.
A collaboration between an international team of researchers has produced the first ever image of a relativistic jet of gas and plasma spewing forth from a pair of galaxies as they dive head-first into one another.
While galaxies have been caught mid-collision plenty of times before, this is the first time a jet of this kind has been seen spilling out of such a merger, and it could tell us a thing or two about how they arise.
Astronomers have used the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) and NASA’s Spitzer Space Telescope to make the first measurement of wind speed on a brown dwarf—an object intermediate in mass between a planet and a star.
Based on facts known about the giant planets Jupiter and Saturn in our own Solar System, a team of scientists led by Katelyn Allers of Bucknell University realized that they possibly could measure a brown dwarf’s wind speed by combining radio observations from the VLA and infrared observations from Spitzer.
“When we realized this, we were surprised that no one else had already done it,” Allers said.
Technicians attached the first-of-its-kind Mars Helicopter to Perseverance’s belly on Monday (April 6) at NASA’s Kennedy Space Center in Florida, where the rover is being prepped for its planned July 17 launch.
Russia seems to see the writing on the wall. No longer can disposable rockets win business for the Russian Space Industry. NASA put an end to the ongoing launches of astronauts into space with the development of domestic. The Russian space industry plans on maintaining or growing market share.
“In 2020, 33 launches are planned, of which 12 launches of satellites under the Federal Space Program, nine launches of commercial vehicles, three from the Guiana Space Center,”
Dmitry Rogozin the head of Roscosmos.
According to https://tass.ru/, Russia is planning on completing 30 commercial launches in 2020. To compete in the international market, Roscosmos announced the cost of launch services will be reduced by more than 30%. The allegation is that American companies are price dumping. With the emergence of SpaceX into the launch sector and other new space companies, the launch vehicle options increased greatly. SpaceX specifically has captured a lot of commercial launch contracts with the partially reusable Falcon 9 rocket. SpaceX has proven the booster reuse capability up to five times and disclosed that the reusability is much greater.
Dmitry Rogozin’s claim of American companies engaging in price dumping may not be a valid comparison. American companies diversified the supply. New innovative rockets have been designed, built and launched by American companies like SpaceX and Rocket Lab.
O,.o circa 2017.
Astronomers from the Sloan Digital Sky Survey used the most luminous objects in the universe — quasars — to create their new 3D map of space.
