Comparison of planet radius distributions and radius–period diagrams across stellar age bins. Upper panels: Planet-radius histograms for four equally populated age bins, defined by the 25th, 50th, and 75th percentiles
ISO Short Wavelength Spectrometer (SWS) spectrum of the Galactic source, W33A, an extremely embedded high-mass young stellar object (Gibb et al. 2004). This source exhibits strong ice absorption features due
(a) 1 mm continuum image of G358.93-0.03. Contour levels correspond to (20, 40, 80, 120, 200, 500, 1000, 1700) × σ, where σ is the rms noise level. The white
This image, taken on Oct. 5, 2025 by the MAVEN spacecraft, shows the coma of gas and dust surrounding comet 3I/ATLAS. Combining data from NASA’s MAVEN, James Webb Space Telescope,
Taking the last sample from the interior of Schiaparelli in the clean tent at the launch site to make sure that the entry, descent and landing module meets the strict
Left panel: Original L-band detection of CC1 in Close et al. (2025a). Middle panel: New H-band detection of WISPIT 2c following RDI. We show a confined annulus that was used
Chloroplasts/kleptoplasts are shown in green, and pyrenoids are shown in yellow. a R. viridis ingests whole cells of a specific Tetraselmis strain by phagocytosis (ingestion event), typically consuming them within
