The unusual terrain on the surface of Uranus’s moon Ariel has an elastic thickness of 4–11 km in the regions studied, which could lead to a wide range of heat fluxes, depending on its composition.
Disks of fast radio burst host galaxies contribute substantially to signal scattering, while the intergalactic medium and host galaxy halos contribute more to dispersion measures, both of which complicate host galaxy determination.
Simulations are able to produce Sun-like rotation and magnetic activity cycles, and they suggest that the ratio of stellar rotation period to magnetic activity cycle length is a constant.
Galaxies with bent active galactic nucleus jets are more likely to be found in galaxy clusters than those with unbent jets, though a curious few galaxies with bent jets reside in regions that lack other galaxies.
Magnetic fields are known to align silicate dust grains, resulting in polarization of starlight, and though carbon-rich dust grains have no such intrinsic alignment, they might be aligned by radiation pressure.
New estimates of the abundance of a radioactive isotope of calcium suggest that this it is 1,000 times more abundant than expected, which yields clues to the enrichment pathway for this species.
