Key Questions
What 'impossible' early galaxies did JWST discover?
JWST found early galaxies challenging Lambda-CDM model via JADES, appearing too evolved too soon. They grew quickly post-Big Bang. This questions standard cosmology.
What is special about the pristine star SDSS J0715-7334?
SDSS J0715-7334 in LMC halo is the most pristine PopIII-like star, with minimal heavy elements, revealing early universe star formation. Discovered by students, it migrated to Milky Way. It shows dawn of stars and galaxies.
What unexpected feature does exoplanet TOI-5205b have?
TOI-5205b, a forbidden giant around a small red star, has a metal-poor atmosphere shocking scientists. JWST data revealed this. It orbits a low-mass host unusually.
What did JWST observe in W51 and protoplanetary disks?
JWST captured protoplanetary disks and W51 protostars, showing planet formation with edge-on views and glowing gas. ALMA complemented findings 450 light-years away. This reveals 'invisible' star birth.
How many rocky planets in habitable zones were found?
JWST identified 45 rocky planets in habitable zones (HZ). These expand exolife search possibilities. Tied to ELF and HWO efforts.
What optics advancement for HWO did JWST enable?
HWO uses UV metasurface coronagraphs for exo-biosignatures, building on JWST. This tech blocks starlight for direct imaging. It targets life detection.
What do Abell 2744 and JADES contribute to JWST findings?
Abell 2744 cluster and JADES survey show massive early structures defying models. JWST images reveal unexpected maturity. This fuels cosmology debates.
How does the pristine LMC star inform early universe?
The LMC PopIII star has barely any heavy elements, indicating slow accumulation over billions of years. It formed in dwarf galaxy halo. Astronomy students led discovery.
