A strange-looking telescope that scanned the skies from a perch in northern Chile for 15 years has released its final data set: detailed maps of the infant universe showing the roiling clouds of hydrogen and helium gas that would one day coalesce into the stars and galaxies we see today.
The Atacama Cosmology Telescope is not the first to survey the cosmic microwave background (CMB), the light released 380,000 years after the Big Bang when the early universe’s soup of particles formed atoms and space became transparent. But the data—posted as preprints online today—give researchers a new level of detail on the density of the gas clouds and how they were moving.
Using the data, researchers tested how well the standard cosmological theory, known as lambda cold dark matter, described the universe at that time 13.8 billion years ago; it’s a remarkably good fit, they conclude.
