First stars and primordial gases, illustration. At lower right is one of the universe's first, massive, blue stars, embedded in gaseous filaments (blue). The cosmic microwave background (red) is seen around the edges at left and top. This illustration is based on radio observations of the distant and early universe, about 180 million years after the Big Bang. Although the light from the massive stars is not seen directly, their presence is inferred from dimming of the cosmic microwave background (CMB. The CMB is dimmer than expected, indicating that the filaments may have been colder than expected, possibly from interactions with dark matter. Image published in 2018. | |
