Planck refines our knowledge of the Universe's composition and evolution New maps provide excellent evidence for By analyzing the patterns of clumps, scientists can learn how conditions even earlier in the universe, just moments after its birth, set the clumping process in motion. "Imagine investigating the foundations of a house and finding that parts of them are weak. Furthermore, a cold spot extends over a patch of sky that is much larger than expected. The Planck image is the highest resolution and most detailed CMB ever created, and will allow scientists to map the composition and evolution of the Universe … And it pushes down what fraction of everything in the universe is dark energy, from 71.4% to 69.2%. and Terms of Use. expansion rate -- called the Hubble constant -- at 67.4 (+/- 0.5) km/sec/Mpc. discussion and part may be reproduced without the written permission. Planck's most detailed map ever reveals an almost perfect Universe by European Space Agency The anisotropies of the Cosmic microwave background (CMB) as observed by Planck. Overall, the information extracted from Planck's new map provides an excellent confirmation of the standard model of cosmology at an unprecedented accuracy, setting a new benchmark in our manifest of the contents of the Universe. Additionally, the "final" 2018 Planck data "With the most accurate and detailed maps of the microwave sky ever made, Planck is painting a new picture of the Universe that is pushing us to the limits of understanding current cosmological theories," says Jan Tauber, ESA's Planck Project Scientist. The all-sky map released now is based on the first 15.5 months of observations with the Planck space telescope, a mission of the European Space Agency (ESA), and shows the oldest light in the universe. [33] [34] The map suggests the universe is slightly older than previously thought. Normal matter that makes up stars and galaxies contributes just 4.9% of the mass/energy density of the Universe. The latest study does not rule out the potential relevance of the anomalies but they do mean astronomers must work even harder to understand the origin of these puzzling features. European Space Agency, At 67.15��kilometres per second per megaparsec, this is significantly less than the current standard value in astronomy.
