A supermassive black hole 6 billion times the mass of the Sun lurks in MRG-M0138, a gravitationally lensed quiescent galaxy seen when the Universe was just 3 billion years old, according to an analysis of data collected by the NIRSpec Integral Field Spectrograph onboard the NASA/ESA/CSA James Webb Space Telescope.

Why are Astronomers Stunned by Abundant Oxygen in Earliest Known Galaxy?

Astronomers have discovered a galaxy, allegedly dating from just 300 million years after the big bang, with unexpectedly high oxygen levels. This is in contradiction to existing cosmological models with galaxy formation taking much longer. The findings refute the validity of the big bang story itself.

James Webb Space Telescope | Little Red Dot Galaxies are a Big Big Bang Problem

In 2022, the James Webb Space Telescope discovered six massive Little Red Dot galaxies dated 500–800 million years post-Big Bang. Their presence challenges the Ξ›CDM cosmological model, as they contain unexpectedly high stellar masses. Recent findings have increased their count to 341, raising questions about galaxy formation and the validity of current theories.
