A white dwarf and a pre-white dwarf, orbiting one another every 28 minutes, will someday cause a supernova through either a merger or the dynamically driven double-degenerate double-detonation channel.

Deep millimeter-wavelength observations did not detect dust emission from 60 little red dots, suggesting that these enigmatic objects are either only modestly dusty or contain extremely dense gas.

Rumors of comet C/2021 O3 (PanSTARRS)’s death may have been exaggerated: according to research, the comet likely emerged from perihelion with its nucleus no larger than 3.4 km across.

Laboratory experiments show that illumination causes erosion on the sides of dusty slopes, reducing the angle of the slope; when the light is turned off, the slope can be reduced further due to amplified emission.

Analysis of JWST imaging of Wolf–Rayet stars shows that dust produced by these stars is long lived, surviving at least 130 years and up to more than 300 years, suggesting that this source could contribute significant dust to our galaxy.
