Terbium, a chemical element with the symbol Tb and atomic number 65, has never before been seen in an exoplanet atmosphere. This illustration shows how the ultrahot Jupiter KELT-9b sees its host star. Image credit: NASA’s Goddard Space Flight Center / Chris Smith, USRA. First discovered in 2016, KELT-9b is a gas giant approximately 2.8 times more massive than Jupiter but only half as dense. This exoplanet orbits KELT-9 — the hottest, most...

The left panel shows a three-color composite mosaic of NGC 346 combining Webb’s F277W (blue), F335M (green) and F444W (red) filters. The region is rich in structures of knots, arcs and filaments. Areas of bright pink and/or red emission are associated with clumpy star formation. The spatially resolved PAH emission excited by ultraviolet photons in green is brightest in regions corresponding to the edges of dense material, characteristic of a photodissociation region. Massive stars, stars belonging to the BS90 cluster (circled in green) and the Small Magellanic Cloud field population are also visible. The right panel shows a mosaic image from the F335M filter showing four different populations of stars: pre-main-sequence stars (blue circles), young stellar objects with Paα (orange diamonds), young stellar objects without Paα (red squares) and stars matched with the HST-PMS catalogue (purple stars).
