This image unveiled March 21, 2013, shows the cosmic microwave background (CMB) as observed by the European Space Agency's Planck space observatory. Image released Jan 17, 2017. The image was obtained by the Planck spacecraft. Discoveries from Planck May Mean Rethinking How the Universe Began. The Planck mission has imaged the oldest light in our universe, called the cosmic microwave background, with unprecedented precision. Regions with less mass show up as lighter areas while regions with more mass are darker. The Planck unit of length has become known as the Planck length, and the Planck unit of time is known as the Planck time, but this nomenclature has not been established as extending to all quantities. The new estimate of dark matter content in the universe is 26.8 percent, up from 24 percent, while dark energy falls to 68.3 percent, down from 71.4 percent. Please refresh the page and try again. It shows the main events that occurred between the initial phase of the cosmos — where its properties were almost uniform and punctuated only by tiny fluctuations — to the rich variety of cosmic structure that we observe today, ranging from stars and planets to galaxies and galaxy clusters. ], This is an artist's concept of the Planck spacecraft. Towards the end of his life, Max Planck strove passionately to re-infuse scientific practice with the sense of honesty and love which animated the greatest discoveries of human history including his own discoveries of the quantum and Planck’s constant. 31 August 2016 ESA's Planck satellite has revealed that the first stars in the Universe started forming later than previous observations of the Cosmic Microwave Background indicated. This tone represents sound waves that traveled through the early universe, and were later "heard" by the Planck space telescope. Planck was launched with the Herschel spacecraft, though the two missions separated shortly after launch and operate independently from each other. Called the cosmic microwave background, this light reveals secrets of the universe's origins, fate, ingredients and more. The age, contents and other fundamental traits of our universe are described in a simple model developed by scientists, called the standard model of cosmology. This map shows the oldest light in our universe, as detected with the greatest precision yet by the Planck mission. Image credit: ESA/NASA/JPL-Caltech © These new data have allowed scientists to test and improve the accuracy of this model with the greatest precision yet. ], This full-sky map from the Planck mission shows matter between Earth and the edge of the observable universe. Acquired by ESA’s Planck space telescope, the most detailed map ever created of the cosmic microwave background – the relic radiation from the Big Bang – was released today revealing the existence of features that challenge the foundations of our current understanding of the Universe. Dark Energy/Matter. [/caption] The launch of the Herschel and Planck spacecraft is scheduled for 13:12 GMT (9:12 EDT) this morning (Thursday). In this image, the two anomalous regions have been enhanced with red and blue shading to make them more clearly visible. "As that ancient light travels to us, matter acts like an obstacle course getting in its way and changing the patterns slightly," said Charles Lawrence, the U.S. project scientist for Planck at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "The Planck map reveals not only the very young universe, but also matter, including dark matter, everywhere in the universe.". The results indicated that the data quality is excellent. › Full image and caption "This is the beginning of a new journey, and we expect our continued analysis of Planck data will help shed light on this conundrum.". "On one hand, we have a simple model that fits our observations extremely well, but on the other hand, we see some strange features which force us to rethink some of our basic assumptions," said Jan Tauber, the European Space Agency's Planck project scientist based in the Netherlands. [Full story. You can watch it live, … Regions with more mass show up as lighter areas while regions with less mass are darker. The project was started around 1996 and was initially called COBRAS/SAMBA: the Cosmic Background Radiation Anisotropy Satellite/Satellite for Measurement of Background Anisotropies. NASA contributed mission-enabling technology for both of Planck's science instruments, and U.S., European and Canadian scientists work together to analyze the Planck data. › Latest images Planck launched in 2009 and has been scanning the skies ever since, mapping the cosmic microwave background, the afterglow of the theorized big bang that created our universe. [Full story. Planck is a European Space Agency mission. The CMB is a snapshot of the oldest light in our Universe, imprinted on the sky when the Universe was just 380 000 years old.
