Researchers at the Technion—Israel Institute of Technology have, for the first time, measured the temporal duration of individual pulses of an extraordinary form of quantum light known as bright squeezed vacuum (BSV). Their findings are published in Optica.
Astrophiles are eagerly awaiting the launch of the National Aeronautics and Space Administration’s Artemis II on Wednesday, which is set to be the most powerful rocket launch on record and will send human beings back toward the moon for the first time in over 50 years.
The Artemis II mission launches this week as a first step toward returning to the moon and reaching Mars. Materials scientist Debbie Senesky explains the material tech that makes these missions possible.
Emma Soto toured the valley in a helicopter, joined the SWAT team in clearing a “house” in a simulated village and called out her movements over a radio under the call sign Moana-1
The Artemis II mission, scheduled to launch on Wednesday, will send four astronauts on a 10-day journey from Earth around the moon—the first time humans will travel that far into space since 1972. While the crew will not land on the moon, the mission marks a major step toward returning people to the lunar surface.
Every mission to deep space is fraught with danger. A hardware failure during launch, an equipment malfunction far from Earth, or a small space rock hitting the vehicle are all scenarios astronauts will train for.
NASA begun fueling its moon rocket Wednesday for humanity’s first lunar trip in more than half a century, aiming for an evening liftoff with four astronauts.
Using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), Chinese astronomers have explored the behavior of a rotating radio transient (RRAT) known as RRAT J1574+4703. The new observations found that this object switches between RRAT and normal pulsar states. The finding was detailed in a paper published March 25 on the arXiv pre-print server.
Using high-intensity lasers, researchers have taken an important step toward miniaturization of particle accelerators by demonstrating free-electron laser amplification at extreme ultraviolet wavelengths (27–50 nm), with an acceleration length of only a few millimeters. By generating high-quality, monoenergetic electron beams (i.e. beams where all the electrons have nearly the same energy), they have achieved a key milestone toward compact accelerator technologies.
Historical observations from an observatory in Germany have now independently verified evidence for brief, mysterious flashes of light in the night sky, first picked up by an American astronomical survey in the 1950s. Through fresh analysis of a German survey from the same period, independent researcher Ivo Busko, a now-retired developer at NASA, has uncovered striking new support for these puzzling signals. The results have been published as a preprint on arXiv.
On Wednesday three men and one woman are set to embark on the first crewed journey to the moon since 1972, a landmark odyssey that aims to launch the US into a new era of space exploration.
Saturn’s magnetic shield is asymmetrical compared to Earth’s, suggests a new study involving University College London (UCL) researchers, and this is likely a result of its fast rotation coupled with the heavy material it pulls around it.
Jason Heath had ventured with his family from northeastern Maine to the Sunshine State for a vacation—but soon found out they were set to “witness history” with the launch of NASA’s Artemis 2 mission.
After weeks of fuel leaks and other issues, NASA faced a trouble-free countdown Tuesday on the eve of astronauts’ first trip to the moon in more than half a century.
At 13:24:59 Central Standard Time on December 19, 1972, the Apollo 17 command module splashed down in the Pacific Ocean, about 350 nautical miles southeast of Samoa, concluding the last mission to the moon.
