Wish I would be religious, so that I could at least pray that trump won't commit anymore war crimes against civilian in #Iran in the upcoming hours, instead of just feeling so hopeless and impotent towards this nonsense, which ourselves and mostly our children will keep paying in the upcoming future.
And who will suffer first are the innocents in #Iran who did nothing wrong against the US, and have already suffered more than enough the Islam theocracy and its many repressions.

A new radio analysis of the double radio relic (=pairs of expanding merger shock waves, ~Megaparsec wide) in the merging cluster of galaxies MACS
J1752.0+4440
by M. Della Chiesa et al. today on #astroph https://arxiv.org/pdf/2604.02410

Deep multi-wavelength radio observations allow to study how radio emitting electrons age in different part of the relic, helping to better understand the plasma properties in regions deeply affected by shocks

JWST image of Arp 220, also known as IC 4553.

Arp 220 is actually two spiral galaxies in the process of merging. Their two cores are about 1,200 light-years apart. The merger sparked an enormous burst of star formation, creating a star-forming ring in each core. These two adjacent, small, bright areas are responsible for the six large diffraction spikes that dominate the image.

I have a truly SPECTACULAR image from JWST of a nebula and star cluster that will rock your universe!

Bonus: A JWST map of dark matter, so, whoa.

Westerlund 2 is a feast for the eyes, and the dark matter map a feast for the brain
