ESA's Hera space mission is on its way to the mission target, the binary asteroid (65803) Didymos. HyperScout-H, one of the instruments onboard Hera, is a hyperspectral imager operating in the visible and near-infrared regions between 0.65 and 0.95 μ m. HyperScout-H will enable a detailed assessment of the composition of both objects, Didymos and

Sub-Neptune-sized exoplanets are the most common class discovered by transit surveys, yet their detailed exploration has just begun. Their demographics have inspired models of planetary formation and evolution, though the sample is naturally biased toward the predominance of M-dwarf systems, which provide more favourable observing conditions. We

We report the discovery and characterization of the multiplanetary system around TOI-4311, a K dwarf kinematically between the Galactic thick disc and Hercules stream. TOI-4311 hosts an ultra-short-period super-Earth (P $\sim$0.99 d, $1.376^{+0.077}_{-0.080}$ R $_{\oplus }$) and a longer period sub-Neptune (P $\sim$15 d, $2.47^{+0.12}_{-0.11}$ R $_

We present the TESS-based discoveries of planetary systems orbiting the late G dwarfs TOI-2494 and TOI-5143, each of which harbors a hot giant planet and a smaller interior planet. TOI-2494 hosts a transiting mini-Neptune (P = 2.41 days, R P = 2.3 5 − 0.15 + 0.16 R ⊕) and a hot Saturn (P = 8.38 days) with grazing transits, while TOI-5143 hosts a

The Galactic Bulge, as the center of the Galaxy, is the closest laboratory for studying galaxy formation and evolution. However, its study faces significant challenges due to heavy dust extinction. This paper is devoted to deriving the average age of the Galactic Bulge and investigating its spatial distribution. We utilize a high-precision PSF

Context. Dark galaxies are small, dark matter-dominated haloes whose gas remains in hydrostatic and thermal equilibrium and has never formed stars. These systems are of particular interest because they represent a strong prediction of the Lambda cold dark matter (ΛCDM) model. As of today, only a few dark galaxy candidates have been detected so far
