Whether you’re a six-year-old scouring the backyard on Easter morning, or an exoplanet astronomer with observing time on the James Webb Space Telescope, nothing beats the feeling of finding what you’re looking for. So, you can imagine the authors of today’s paper were pretty excited when they received their transmission spectroscopy data of the sub-Neptune known as TOI-270d.

Why do we see so many massive, dead galaxies at early cosmic times? Guest author Tatevik Mkrtchyan illuminates a slice of the cosmic graveyard!
Today’s bite explores a new method to find the galaxies hosting the Universe’s first generation of stars
Galaxy-modelers beware! Today’s bite will guide you through an analysis of CEERS2-588, a quirky, UV-luminous, early galaxy discovered by JWST that’s causing issues in our theoretical models!
So we have a pretty good idea of how old the Universe is right? Well according to JWST data, maybe not? Rest assured, today’s bite gets to the bottom of the debate.
Something is missing in the middle. In JWST JADES galaxies, young clumps drop out in the inner regions, while clump structure shifts from the outskirts to the center.
