Four separate astronomy findings and mission selections have been published by research teams this week.

Astronomers using the European Southern Observatory's Very Large Telescope imaged a shock wave around white dwarf RXJ0528+2838, located 730 light-years away[^1]. The James Webb Space Telescope was used to identify HD 3167 b, a rocky exoplanet approximately 154 light-years from Earth[^2]. Webb also formed the core of new work on extreme debris discs around young stars, with teams cross-referencing data against observations from the retired Spitzer Space Telescope[^4].

NASA has selected a Planetary Science Institute-led proposal to map whether a large underground cave extends beyond the visible opening of the Marius Hills pit on the Moon[^3].
