The Sustained Spheromak Physics Experiment (SSPX) is a program at Lawrence Livermore National Laboratory in the United States established to investigate spheromak plasma. [ 1 ] A spheromak device produces a plasma in magnetohydrodynamic equilibrium mainly through self-induced plasma currents , as opposed to a tokamak device which depends on ...

The canonical situation of the Society of Saint Pius X (SSPX), a group founded in 1970 by Archbishop Marcel Lefebvre, is unresolved.The Society of Saint Pius X has been the subject of much controversy since 1988, when Bernard Fellay, Bernard Tissier de Mallerais, Richard Williamson and Alfonso de Galarreta were illicitly consecrated as bishops at Ecône, at the International Seminary of Saint ...
The mass of the observable universe is often quoted as 10 53 kg. [48] In this context, mass refers to ordinary (baryonic) matter and includes the interstellar medium (ISM) and the intergalactic medium (IGM). However, it excludes dark matter and dark energy. This quoted value for the mass of ordinary matter in the universe can be estimated based ...
The Star-Spectroscope of the Lick Observatory in 1898. Designed by James Keeler and constructed by John Brashear.. Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, ultraviolet, X-ray, infrared and radio waves that radiate from stars and other celestial objects.
A successful large-scale simulation of the evolution of galaxies, with results consistent with what is actually seen by astronomers in the night sky, provides evidence that the theoretical underpinnings of the models employed, i.e., the supercomputer implementations ΛCDM, are sound bases for understanding galactic dynamics and the history of the universe, and opens avenues to further research.
Discovered through gamma-ray burst mapping. Largest-known regular formation in the observable universe. [8] Huge-LQG (2012–2013) 4,000,000,000 [9] [10] [11] Decoupling of 73 quasars. Largest-known large quasar group and the first structure found to exceed 3 billion light-years. "Giant Arc" (2021) 3,300,000,000 [12] Located 9.2 billion light ...
The co-moving wavenumber corresponding to the maximum power in the mass power spectrum is determined by the size of the cosmic particle horizon at the time of matter-radiation equality, and therefore depends on the mean density of matter and to a lesser extent on the number of neutrino families (), = (/) =, for = .
