Moon erosion by solar wind far weaker than previously believed
The surface of the Moon is constantly exposed to the solar wind-a stream of charged particles from the Sun that can dislodge atoms from the lunar surface and contribute to its thin exosphere. However, a new study by Vienna University of Technology (TU Wien) and international collaborators reveals that earlier models greatly overestimated this sputtering effect.
The researchers attribute th Flash frozen silicon reveals patterns mirroring early universe dynamics
A team of physicists from Helmholtz-Zentrum Dresden-Rossendorf (HZDR), University of Duisburg-Essen, and University of Alberta has discovered that ultra-fast cooling of silicon surfaces produces structural patterns that echo the cosmic phase transitions theorized to have occurred shortly after the Big Bang. Their study shows that the rate at which silicon cools drastically influences how atoms a Using soft X-rays to track magnetic reconnection may advance space weather forecasting
A research team from Chiba University has demonstrated how soft X-ray imaging could be used to monitor magnetic reconnection rates in Earth's magnetosphere-a critical development in improving space weather forecasting. Magnetic reconnection, a process where solar wind penetrates Earth's magnetic barrier, can disrupt satellite operations and communication systems.
Led by Associate Professor XRISM mission maps sulfur distribution across Milky Way
An international research team has made the first direct measurement of sulfur in both its gas and solid forms in interstellar space, using X-ray data from the Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) satellite.
Utilizing observations from two distant X-ray binary systems, astronomers detected sulfur throughout the interstellar medium-the vast mix of dust and gas between st SpaceX launches satellites from California, Florida day after scrubs
SpaceX launched two Falcon 9 rockets with satellite payloads after they were scrubbed less than a minute before liftoff one day earlier in Florida and California.
In both situations, the rockets and payloads were in good health.
On Wednesday, the private agency launched two Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites, or TRACER, for NASA at 2:13 p.m. PD Seismic signatures reveal fragmentation patterns of fireball meteoroids
Seismic data can distinguish between intact and fragmented fireball meteoroids during atmospheric entry, according to a new study published in Seismological Research Letters. Researchers led by Iona Clemente of Curtin University analyzed seismic signals from several fireball events, including the 2020 return of Japan's Hayabusa2 sample capsule, to test this approach.
