The universe's size is unknown, and it may be infinite in extent. [14] Some parts of the universe are too far away for the light emitted since the Big Bang to have had enough time to reach Earth or space-based instruments, and therefore lie outside the observable universe. In the future, light from distant galaxies will have had more time to ...
Map is one of the most precise measurements of how ‘stuff’ is distributed through the cosmos
The portion of the universe that can be seen by humans is approximately 93 billion light-years in diameter at present, but the total size of the universe is not known. [3] Some of the earliest cosmological models of the universe were developed by ancient Greek and Indian philosophers and were geocentric, placing Earth at the center.
a map of galaxy voids. This is a list of voids in astronomy. Voids are particularly galaxy-poor regions of space between filaments, making up the large-scale structure of the universe. Some voids are known as supervoids.
2020 – After a 20-year-long survey, astrophysicists of the Sloan Digital Sky Survey publish the largest, most detailed 3D map of the universe so far, fill a gap of 11 billion years in its expansion history, and provide data which supports the theory of a flat geometry of the universe and confirms that different regions seem to be expanding at ...
The Digital Universe Atlas has spun off a commercial-grade planetarium platform from SCISS called Uniview that was featured in the White House star party on October 7, 2009. The Atlas database and Partiview interface is compatible with professional planetarium software such as Evans & Sutherland's Digistar and Sky-Skan's DigitalSky 2.
The first five images captured by the Euclid telescope showcase glimmering clusters of galaxies and stars. The telescope, launched in July, was designed to create the most detailed 3D map of the ...
The universe is generally understood to have begun with the Big Bang, followed almost instantaneously by cosmic inflation, an expansion of space from which the universe is thought to have emerged 13.799 ± 0.021 billion years ago. [8] Cosmogony studies the origin of the universe, and cosmography maps the features of the universe.
