A laboratory study of nanometer-sized dust grains in simulated Martian soil helps scientists explore thermal creep, a process in which gases flow out of porous soil.

Recent research delves into the method by which turbulence transfers energy to cosmic rays: high-energy charged particles accelerated by supernovae and other cosmic sources.

Shock heating likely explains the observed dust temperature in the vicinity of a triple class 0 protostellar system; the class 0 stage of stellar evolution likely lasts about 10,000 years.

Using machine learning, a research team discovered thousands of new star clusters in the Milky Way’s disk, boosting the number of star clusters cataloged from Gaia spacecraft data to nearly 6,000.

Simulations suggest that semi-periodic X-ray flares could be due to main-sequence stars on eccentric orbits around black holes; the star loses mass to the black hole, and the resulting flare causes further mass loss.

Despite having the tell-tale signs of a galaxy cluster, like X-ray-emitting gas, 3C 297 appears to contain just a single galaxy, which might mean that the galaxies of an ancient cluster merged long ago.
