Deep optical and ultraviolet observations of a young, massive star cluster in the Large Magellanic Cloud find no evidence of multiple populations among the evolved red giant branch stars, unlike other clusters.
A survey of young stars that are surrounded by disks but appear not to be accreting material reveals that 20–30% of these so-called non-accretors are still collecting material, albeit at a reduced rate.
Wind tunnel simulations show that electrical charging of dust grains might mean that particle transport on Mars’s surface can be restarted more easily after winds die down than previously thought.
New laboratory experiments demonstrate that grains of carbon dioxide ice stick together when they collide at velocities at or below 0.1 meter per second, but begin to fragment at velocities above one meter per second.
A lensed galaxy discovered to contain low-excitation molecular gas may represent a missing link between starburst galaxies and low-luminosity galaxies during cosmic noon.
Measuring the distribution of energy at infrared wavelengths in nearby galaxy M31 demonstrates how supernovae heat their local environments and allows for estimation of how much dust is destroyed in the blast.
