Limits on the 21 cm Power Spectrum at z = 6.5–7.0 from Murchison Widefield Array Observations This paper presents the spherically averaged 21 cm power spectrum derived from Epoch of Reionization (EoR) observations conducted with the Murchison Widefield Array (MWA). The analysis uses EoR0-field data, centered at (R.A. = 0h, decl. = ‑27<SUP>∘</SUP>), collected between 2013

JWST discovers how we're able to see the Universe at all For hundreds of millions of years, a cosmic fog blocked all signs of starlight. At last, JWST found the galaxies that cleared that fog away.

JWST discovers how we’re able to see the Universe at all

It's only because all of the neutral atoms in intergalactic space became ionized that we can see so far away through space.

JWST, at last, has found who the culprit is.
