Wow wee, wow wow! JWST just keeps raising more questions than it's answering--& that's a good thing! JWST discovered that the toddler galaxy, GS-z13-1--which existed just 330 million years after the Big Bang--had ionized the ancestral neutral hydrogen that surrounded it allowing its light to transverse the universe & reach JWST. According to present hypothesis, that's incredibly early for a galaxy to have done that. esa.int/Science_Exploration/Sp

www.esa.intWebb sees galaxy mysteriously clearing fog of early UniverseUsing the unique infrared sensitivity of the NASA/ESA/CSA James Webb Space Telescope, researchers can examine ancient galaxies to probe secrets of the early Universe. Now, an international team of astronomers has identified bright hydrogen emission from a galaxy in an unexpectedly early time in the Universe’s history. The surprise finding is challenging researchers to explain how this light could have pierced the thick fog of neutral hydrogen that filled space at that time.

3D map of #exoplanet #atmosphere shows wacky climate
#Astronomers have mapped the 3D structure of the layered atmosphere of one such ultra-hot #Jupiter-size exoplanet, revealing powerful winds that create intricate #weather patterns across that atmosphere.
"This planet’s atmosphere behaves in ways that challenge our understanding of how weather works."
#Astronomy and #Astrophysics reported on unexpected identification of #titanium in the exoplanet's atmosphere as well.

Our Fascinating Universe

JWST has captured Neptune’s auroras for the first time! The most distant planet from the Sun has a magnetic field tilted at a strange 47-degree angle, causing auroras away from its poles. Webb also found Neptune’s upper atmosphere has cooled by hundreds of degrees—likely why its auroras remained undetected for so long.

"But there are indeed (at least) four major discoveries — purely serendipitous discoveries, that only occurred because we dared to look at the Universe as we’ve never looked at it before — that have truly shown us aspects of the Universe that were total surprises. Because of them, our cosmic picture is forever changed."
