Researchers have developed a novel technique to investigate the dynamics of the early Solar System by analyzing magnetites in meteorites utilizing the wave nature of electrons.

Within meteorites, the magnetic fields associated with the particles that make up the object can act as a historical record. By analyzing such magnetic fields, scientists can deduce the probable events that affected the object and reconstruct a time-lapse of what events occurred on the meteorite and when.

“Primitive meteorites are time capsules of primordial materials formed at the beginning of our Solar System,” said Yuki Kimura, an associate professor at the Institute of Low Temperature Sci...

Stars scattered throughout the cosmos look different, but they may be more alike than once thought, according to Rice University researchers.

New modeling work by Rice scientists shows that “cool” stars like the sun share the dynamic surface behaviors that influence their energetic and magnetic environments. This stellar magnetic activity is key to whether a given star hosts planets that could support life.

The work by Rice postdoctoral researcher Alison Farrish and astrophysicists David Alexander and Christopher ...

Research paper provides new insights into how central supermassive blackholes influence the evolution of their host galaxy. Galaxies eventually undergo a phase in which they lose most of their gas, which results in a change into their properties over the course of their evolution. Current models for galaxy evolution suggest this should eventually happen to all galaxies, including our own Milky Way; astronomers have now uncovered key insights into this process.

Emirati national Aisha Al Yazeedi, a research scientist at the NYU Abu Dhabi (NYUAD) Center for Astro, Particle, and Planetary Physics, has published her first research paper, featuring some key findings on the evolution of galaxies.

Commenting on the findings, Al Yazeedi said: “The evolution of galaxies is directly linked...

Scientists in Australia and in the USA have solved a long-standing mystery about the Sun that could help astronomers predict space weather and help us prepare for potentially devastating geomagnetic storms if they were to hit Earth.

The Sun’s internal magnetic field is directly responsible for space weather — streams of high-energy particles from the Sun that can be triggered by solar flares, sunspots or coronal mass ejections that produce geomagnetic storms...
