stars around it (purple dots), and then the Local Group of other galaxies around our To go back even further, they used quasars, galaxies whose supermassive black hole is extremely luminous.The map reveals that the expansion of the Universe began to accelerate at some point and has since continued to do so.The researchers said this seems to be due to the presence of dark energy, an invisible element that fits into Albert Einstein's general theory of relativity but whose origin is not yet understood.Astrophysicists have known for years that the Universe is expanding, but have been unable to measure the rate of expansion with precision.Comparisons of the eBOSS observations with previous studies of the early universe have revealed discrepancies in estimates of the rate of expansion.The currently accepted rate, called the "Hubble constant", is 10 percent slower than the value calculated from the distances between the galaxies closest to us.Take international news everywhere with you! manually.

Astrophysicists on Monday published the largest-ever 3D map of the Universe, the result of an analysis of more than four million galaxies and ultra-bright, energy-packed quasars. spherical swarm of stars, and that open star clusters form a larger swarm, also Over the past decade, 3D modeling and 3D printing in science has blossomed while commercial 3D printers have become more common. In the project launched more than two decades ago, the researchers made "the most accurate expansion The map relies on the latest observations of the Sloan Digital Sky Survey (SDSS), titled the "extended Baryon Oscillation Spectroscopic Survey" (eBOSS), with data collected from an optical telescope in New Mexico over six years.Astrophysicists release largest 3D map of the universe ever created - The infant Universe following the Big Bang is relatively well known through extensive theoretical models and observation of cosmic microwave background -- the electromagnetic radiation of the nascent cosmos.But Kyle Dawson of the University of Utah, who unveiled the map on Monday, said the researchers tackled a "troublesome gap in the middle 11 billion years".Through "five years of continuous observations, we have worked to fill in that gap, and we are using that information to provide some of the most substantial advances in cosmology in the last decade," he said.Astrophysicist Jean-Paul Kneib of the Swiss Federal Institute of Technology (EPFL) in Lausanne, who initiated eBOSS in 2012, said the goal was to produce "the most complete 3D map of the Universe throughout the lifetime of the Universe".For the first time, the researchers drew on "celestial objects that indicate the distribution of matter in the distant Universe, galaxies that actively form stars and quasars".The map shows filaments of matter and voids that more precisely define the structure of the Universe since its beginnings, when it was only 380,000 years old.For the part of the map relating to the Universe six billion years ago, researchers observed the oldest and reddest galaxies.For more distant eras, they concentrated on the youngest galaxies -- the blue ones. So, the simulation not only shows how the objects of the night sky fit into a 3D structure around the Sun, but also the limitations of how far into the Universe we can see.
