Using the James Webb Space Telescope (JWST), an international team of astronomers has detected a new grand-design spiral galaxy as part of the PANORAMIC survey. The newfound galaxy, named Zhúlóng, is extremely massive and appears to be the most distant spiral galaxy identified so far. The finding was detailed in a paper published December 17 on the pre-print server arXiv.
Grand-design spiral galaxies are characterized by their prominent, well-defined arms, which circle outwards from a clear core. It is assumed that the arms in such galaxies are actually overdense regions of the disk which trigger star formation as incoming material is compressed in that region.
It is still not well understood when and how spiral galaxies first emerged in the early universe and such galaxies are generally rare at high redshifts. To date, only a few individual spirals have been found at a redshift higher than 3.0.

Lt Col Charlie Brown I've wondered sometimes if mankind will ever be able to leave the Solar System must less the Milky Way and other galaxies. It might happen but not in our lifetime!

Just A Couple Days Ago I Was Watching The Travel Channel Or Perhaps The History Channel And A Former Employee Of Area 51, Stated They Were Working With Limited Success On Actually Developing A"Worm Hole", Which Might Be Capable Of Interstellar Travel Taking Place Instantaneously. ...It's Currently Still Being Worked On, Because They Could Only Hold The "Worm Hole" Operational For A Few Seconds And The Energy Required To Hold It Stable Was Inadequate.

I fall back to my wife's theory that God will never let us contaminate his other creations.

62,000 light years across! At approximately 6 trillion miles per light year, that's a mighty big sporal.
