An astronomer at the University of Hawaiʻi at Hilo is using data from the Canada–France–Hawaiʻi Telescope (CFHT) on Maunakea to help reconstruct a slow-motion cosmic collision, one that has been unfolding for hundreds of millions of years. A new study from principal investigator R. Pierre Martin, a professor of astronomy at UH Hilo, and international researchers such as Ph.D. student Camille Poitras and colleagues at Université Laval in Québec, Canada, simulates the past, present, and future of two spiral galaxies, NGC 2207 and IC 2163.

Gravitational waves could be responsible for the production of dark matter during the early phases of our universe’s formation, according to results of a new study by Professor Joachim Kopp from Johannes Gutenberg University Mainz (JGU) and the PRISMA Cluster of Excellence in cooperation with Dr. Azadeh Maleknejad from Swansea University. Their work, published in Physical Review Letters, presents new calculations that explore a novel mechanism for the formation of dark matter through so-called stochastic gravitational waves.

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.

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.

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.
