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.
A survey planned to begin in summer 2026 will characterize the size distribution of Kuiper Belt objects as well as identify potential imaging targets for the New Horizons spacecraft.
Seven years from now, 2024 YR4 will have a few percent chance of impacting the Moon and carving out a 1-km-diameter crater; such an impact has a 1% chance of directing at least 10% of the ejecta to be accreted by Earth.
A sounding rocket will carry for the first time an instrument capable of detecting polarized X-rays below 1 kiloelectronvolt; this work explores the possible outcomes of a dedicated mission with such an instrument.
Reported diameters of dust devils on Mars appear to follow a simple power-law distribution; dust devil diameters are important because the amount of dust injected into the atmosphere scales with the diameter.
A vertical velocity anomaly in the stellar disk of the Milky Way and spatially coincident gaseous disturbances support the hypothesis that a dark or failed ultra-compact dwarf galaxy has passed through the Milky Way.
