「今日新发现:A Map of the Observable Universe」如果你能看到可观测宇宙的边缘呢?你会看到星系、星系、星系,然后是类星体,它们是遥远星系的明亮中心.为了扩大对人类所能看到的最大尺度的理解,斯隆数字巡天在20...
A Logarithmic Map of the Entire Observable Universe Among the scientific community, it’s widely believed that so far humans have only discovered about 5% of the universe. Yet, despite knowing about just a fraction of what’s out there, we’ve still managed to discover galaxies billions of ...
“The map of the observable Universe”, that takes viewers on a 13.7-billion-year-old tour of the cosmos from the present to the moments after the Big Bang. While JHU is responsible for creating the site, additional contributions were made by NASA, the European Space Agency...
Three-dimensional map of the large-scale distribution of dark matter in the observable universe, from Hubble Space Telescope data (NASA, Jan 7, 2007). The map, determined by analysis of gravitational distortions of light coming from distant galaxies, reveals a network of filaments intersecting at...
The map is representative of the entire cosmos, but the final visualization only showsa fraction of the observable universeto increase legibility. A map showing the entire cosmos would have been impossible to render in 2D—instead of a pizza slice, it would have looked like a sphere. The team...
Lifetime of such high energy X-ray sources compared to the Hubble time as an example. Reply Stephen J. Bauer I don't see how they can promote this as a map of the universe. Even the CMB map was only a chunk of what we could picture of the observable universe, from one ...
Our aim is specifically to use the CMB as a backlight -- and survey the gas, total mass, and stellar content of the entire observable Universe by means of analyzing the spatial and spectral distortions imprinted on it. These distortions result from two major processes that impact on CMB ...

even dark matter, has gravity that will affect light traveling to us from near the very edge of the observable universe. Planck mapped this light, called the cosmic microwave background, with exquisite precision over the whole sky, enabling scientists to create this matter map. Credit: ESA/...
On Jul 20, 2020, scientists have released what they call the "largest-ever 3D map of the universe". This map shows 11 billion years of the universe's history.
