How would our world be viewed by observers moving faster than light in a vacuum? Such a picture would be clearly different from what we encounter every day. We should expect to see not only phenomena that happen spontaneously, without a deterministic cause, but also particles traveling simultaneously along multiple paths - argue theorists from universities in Warsaw and Oxford. Also the ve

An international team of scientists led by Lucile Turc, an Academy Research Fellow at the University of Helsinki and supported by the International Space Science Institute in Bern has studied the propagation of electromagnetic waves in near-Earth space for three years. The team has studied the waves in the area where the solar wind collides with Earth's magnetic field called foreshock region, an

Electromagnetic noise poses a major problem for communications, prompting wireless carriers to invest heavily in technologies to overcome it. But for a team of scientists exploring the atomic realm, measuring tiny fluctuations in noise could hold the key to discovery. "Noise is usually thought of as a nuisance, but physicists can learn many things by studying noise," said Nathalie de Leon,

JPL's cutting-edge instrument, which will provide insights into the lunar water cycle and composition of the Moon's surface, has been incorporated into the small satellite. Lunar Trailblazer, NASA's mission to understand lunar water and the Moon's water cycle led by Caltech in Pasadena, California, is one step closer to launching next year. Earlier this month, the agency's Jet Propulsion Laborat

An experiment to bounce a radio signal off an asteroid on Dec. 27 will serve as a test for probing a larger asteroid that in 2029 will pass closer to Earth than the many geostationary satellites that orbit our planet. The High-frequency Active Auroral Research Program research site in Gakona will transmit radio signals to asteroid 2010 XC15, which could be about 500 feet across. The Univer

The InSight Mars mission is history. On 20 December 2022, NASA declared the mission over. The two attempts from Mission Control Centre at NASA's Jet Propulsion Laboratory (JPL) in Southern California to reach the lander via relay satellites in Mars orbit have been unsuccessful. This almost certainly means that InSight's solar-powered batteries are no longer supplying enough power, a condition en

When NASA's Mars rovers found manganese oxides in rocks in the Gale and Endeavor craters on Mars in 2014, the discovery sparked some scientists to suggest that the red planet might have once had more oxygen in its atmosphere billions of years ago. The minerals probably required abundant water and strongly oxidizing conditions to form, the scientists said. Using lessons learned from Earth's

When winter comes to Mars, the surface is transformed into a truly otherworldly holiday scene. Snow, ice, and frost accompany the season's sub-zero temperatures. Some of the coldest of these occur at the planet's poles, where it gets as low as minus 190 degrees Fahrenheit (minus 123 degrees Celsius). Cold as it is, don't expect snow drifts worthy of the Rocky Mountains. No region of Mars g

U.S. Senator John Hickenlooper applauded Senate passage of his Orbital Sustainability (ORBITS) Act, a bipartisan bill to establish a first-of-its-kind demonstration program to reduce the amount of space junk in orbit. The bill passed the Senate unanimously. "From satellite communications to rockets carrying humans into deep space, space debris is a massive threat to space operations," said

Construction is set to begin on NASA's Near-Earth Object Surveyor, a space telescope designed to search for hard-to-find comets and asteroids that approach the area near Earth. The NEO Surveyor passed a technical programmatic review and will now move into the construction phase. "The mission supports the objectives of NASA's Planetary Defense Coordination Office (PDCO) at NASA He
