The universe also has vast regions of relative emptiness; the largest known void measures 1.8 billion ly (550 Mpc) across. Comparison of the contents of the universe today to 380,000 years after the Big Bang as measured with 5 year WMAP data (from 2008). Due to rounding errors, the sum of these numbers is not 100%.
Dark matter (26.8%) Dark energy (68.3%) [6] The observable universe is a ball-shaped region of the universe consisting of all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time; the electromagnetic radiation from these objects has had time to reach the Solar System and Earth since the ...
Currently most of the objects of mass between 10 9 kg to 10 12 kg (less than 1000 teragrams (Tg)) listed here are near-Earth asteroids (NEAs). The Aten asteroid 1994 WR12 has less mass than the Great Pyramid of Giza, 5.9 × 10 9 kg. For more about very small objects in the Solar System, see meteoroid, micrometeoroid, cosmic dust, and ...
This week, see the first cosmic images taken by the Euclid telescope, read 265-year-old letters, uncover the volcanic threat lurking beneath Italy, and more.
The Dark Energy Spectroscopic Instrument (or DESI for short) has created the largest 3D map of the universe we’ve ever seen. DESI created the map over the course of seven months. Each month ...
e. In physical cosmology, the shape of the universe refers to both its local and global geometry. Local geometry is defined primarily by its curvature, while the global geometry is characterised by its topology (which itself is constrained by curvature). General relativity explains how spatial curvature (local geometry) is constrained by gravity.
Cosmic Eye [1] is a short 2012/2018 film and iOS app, developed by astrophysicist Danail Obreschkow. [2] It shows the largest and smallest well known scales of the universe by gradually zooming out from and then back into the face of a woman called "Louise". According to the creator, the film and app were inspired by the essay Cosmic View (1957 ...
The science and philosophy channel Kurzgesagt has come out with a mind-blowing size comparison of the universe's black holes. The post Black Hole Size Comparison Chart Gives New View of Universe ...
