From Nature: The quest to unlock the secrets of the baby Universe To get an idea of what the Universe looks like from Earth’s perspective, picture a big watermelon. Our Galaxy, the Milky Way, is one of the seeds, at the centre of the fruit. The space around it, the...

From KJZZ 91.5 Radio: The story of the universe as we know it and the planet we live on begins with the first star. In 2016, the Hubble Telescope measured the oldest known galaxy in the universe — one that formed 400 million years after the Big Bang. A group...

From Nature: After stars formed in the early Universe, their ultraviolet light is expected, eventually, to have penetrated the primordial hydrogen gas and altered the excitation state of its 21-centimetre hyperfine line. This alteration would cause the gas to absorb photons from the cosmic microwave background, producing a spectral distortion...

From NPR: Scientists have probed a period of the universe's early history that no one has been able to explore before — and they got a surprise: It was far colder in the young universe, before the first stars blinked on, than astronomers previously thought. What's more, that cosmic chill...

From The New York Times: It was morning in the universe and much colder than anyone had expected when light from the first stars began to tickle and excite their dark surroundings nearly 14 billion years ago. Astronomers using a small radio telescope in Australia reported on Wednesday that they...

From Nature: The first stars to form generated copious fluxes of ultraviolet radiation that suffused the early Universe — a phenomenon referred to as the cosmic dawn. Many calculations have been performed to estimate when this occurred, but no data-driven constraints on the timing have been available. In a paper...

From the BBC: Scientists say they have observed a signature on the sky from the very first stars to shine in the Universe. They did it with the aid of a small radio telescope in the Australian outback that was tuned to detect the earliest ever evidence for hydrogen. This...

From CU Boulder Today: For the first time, astronomers have detected a signal from stars emerging in the early universe. Using a radio antenna not much larger than a refrigerator, the researchers discovered that ancient suns were active within 180 million years of the Big Bang. The astronomers, from Arizona...
