"Unexplained Signal Detected Beyond Milky Way by NASA's Fermi Telescope"
NASA astronomers have discovered an unexpected and unexplained gamma-ray signal coming from outside our galaxy while analyzing data from the Fermi Gamma-ray Space Telescope. The signal, detected in a different part of the sky than expected, has created a cosmic conundrum for scientists and could be linked to a similar unexplained feature observed previously. This discovery could challenge current ideas about the universe's creation and provide insight into physical processes in the early universe.
