THE FIRST MOMENTS OF THE UNIVERSE'S LIFE REVEALED IN DETAIL

📎 SPACE TODAY AT THE THEATER: "MARS, OUR NEXT DESTINATION?": APRIL 13 | 4PM | TEATRO GAZETA - SP TICKETS: https://bileto.sympla.com.br/event/10... 📎 VOLCANO WORKSHOP: APRIL 5 https://academyspace.com.br/WORKSHOP/ New research from the Atacama Cosmology Telescope (ACT) collaboration has produced the clearest images yet of the universe's infancy — the earliest cosmic time accessible to humans. The researchers released the images today and will present their results at the American Physical Society's annual conference tomorrow. Measuring light that traveled more than 13 billion years to reach a telescope high in the Chilean Andes, the new images reveal the universe as it was about 380,000 years old—the equivalent of old photos of a middle-aged cosmos taken just a few hours ago. “We’re seeing the first steps toward making the first stars and galaxies,” said Suzanne Staggs, director of ACT and the Henry deWolf Smyth Professor of Physics at Princeton University. “And we’re not just seeing light and dark, we’re seeing the polarization of light in high resolution. That’s a defining feature of ACT.” The new images of this background radiation, known as the cosmic microwave background (CMB), add greater definition to those observed more than a decade ago by the Planck space telescope. “ACT has five times the resolution of Planck and greater sensitivity,” said Sigurd Naess, a researcher at the University of Oslo and former visiting scholar at Princeton who is lead author of one of several papers to be presented alongside the images. “This means that the faint polarization signal is now directly visible.” The polarization image reveals the detailed motion of hydrogen and helium gas in the cosmos’s infancy. “Before, we could see where things were, and now we can also see how they are moving,” said Staggs. “Like using tides to infer the presence of the moon, the motion tracked by the polarization of light tells us how strong the pull of gravity was in different parts of space.” “Through their sheer breadth, depth and attention to detail, the latest ACT results are a testament to the astonishing durability of the standard model of cosmology and the power of CMB measurements to probe everything from the birth of the universe to stellar explosions,” said Page. “The results are also a testament to a great team and the National Science Foundation that made it all possible.” As ACT surveyed the sky, it also saw light emitted by other objects in space. “We can see back through cosmic history,” Dunkley said, “from our own Milky Way, through distant galaxies that host vast black holes and huge galaxy clusters, all the way back to that time in its infancy.” ACT completed its observations in 2022, and attention is now turning to the new, more capable Simons Observatory at the same site in Chile. ACT shares data publicly in NASA’s LAMBDA archive.
