Galaxy – Types of galaxies: Almost all current systems of galaxy classification are outgrowths of the initial scheme proposed by the American astronomer Edwin Hubble in 1926. In Hubble’s scheme, which is based on the optical appearance of galaxy images on photographic plates, galaxies are divided into three general classes: ellipticals, spirals, and irregulars.

The standard cosmological model describes a universe dominated by dark energy and dark matter. Most astronomers assume that dark matter consists of "cold" (i.e. slow-moving) exotic particles that.

The source of the Sun’s energy is A. thermonuclear fusion reactions in which lower-mass nuclei combine to form a higher-mass nucleus. B. fission reactions in which a heavier nucleus splits to form two lighter nuclei.

But it isn’t the first time researchers have claimed to find a supervoid that explains the cold spot. In 2007, radio astronomers. light years across the sky when universe was 11.1 billion years old.

Date Speaker Title ; 04-3-19. Anna Nierenberg (JPL) Testing the nature of dark matter with narrow-line lensing. The abundance of low mass dark matter halos (M_vir <10^8 M_sun) provides key insight into the nature of dark matter, as this abundance depends on the freestreaming length of dark matter at early times and thus its particle properties.

Astronomers have been grappling with the mystery of dark matter for a long time, and I mean a looong time. We see signs of dark matter all across the universe, at a wide variety of scales. It seems.

Nearly tracking Moore’s Law, the growth in simulation size is exponential with a doubling time of approximately 20 months. It is only now, with the available computing power, the sophistication of the numerical approach, and the fidelity of the physical models, that we can simulate a statistically significant volume of the universe down to z=0 with sufficient detail to resolve the internal.
