It blows my mind that they were able to simulate the big bang well enough that running the simulation for a while resulted in stars in the same places as in present reality. That’s crazy.
Astronomy is constantly discovering never-befor observed phenomenon. The idea that you can simulate realistic images of anything requires you to have sufficient knowledge of reality, and astronomy keeps showing us that we don’t have that.
The only way I can see this being helpful is to train algorithms for what is already known and can be safely filtered out, making it easier to detect new observations
Neat to see a 6-7 solar mass black hole spotted. First one without a companion star to give it away! As we get better at finding black holes of this size, will be interesting to see if they end up explaining part of the “dark matter” problem.
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.
