Summary

Story summary

The James Webb Space Telescope raises questions about a potential oldest galaxy, nicknamed Capotauro, dating to 90 million years after the Big Bang.
The finding could reshape our understanding of galaxy evolution.
Researchers are examining a faint gamma-ray glow at the Milky Way’s center that may reflect dark matter interactions.
Origins remain uncertain; theories point to dark matter collisions or fast-spinning neutron stars.

History

Historical Context

The cosmic microwave background radiation (CMB) was first predicted in 1948 by Ralph Alpher and Robert Herman, who estimated its temperature at 5 K. In 1965, Arno Penzias and Robert Wilson accidentally discovered the CMB, measuring it at 2.7 K, providing strong evidence for the Big Bang theory. This discovery has since shaped our understanding of the universe's evolution and dark matter.
