Not exact matches

[2] In 2011, a five - year survey of 200,000 galaxies and spanning 7 billion years of cosmic time confirmed that «dark energy is driving our universe apart at accelerating speeds.»

Astronomers working with the Sloan Digital Sky Survey have used a 2.5 - meter telescope at the Apache Point Observatory in Sunspot, New Mexico, to map the location of more than 930,000 nearby galaxies, determining the distance to each by how much the expansion of the universe has stretched, or «redshifted,» the wavelength of the galaxy's light.

The study led by Donahue looked at far - ultraviolet light from a variety of massive elliptical galaxies found in the Cluster Lensing And Supernova Survey with Hubble (CLASH), which contains elliptical galaxies in the distant universe.

Astronomers expect to find roughly 10 more such systems in the survey, which will provide important insights into the fundamental physics of galaxies as well as how the universe expanded over the last several billion years.

The newly discovered black hole is in a galaxy, NGC 1600, in the opposite part of the sky from the Coma Cluster in a relative desert, said the leader of the discovery team, Chung - Pei Ma, a UC Berkeley professor of astronomy and head of the MASSIVE Survey, a study of the most massive galaxies and black holes in the local universe with the goal of understanding how they form and grow supermassive.

Science Interests Formation of galaxies and black holes in the early universe and their growth over cosmic time; large surveys with Hubble and other telescopes to discover new populations of distant galaxies and black holes; physical properties of active galactic nuclei using observations from radio, infrared, optical, ultraviolet through to X-ray energies.

The survey's researchers analyzed light from 26 million galaxies to study how structures in the universe have changed over the past 7 billion years — half the age of the universe.

While, the newly discovered galaxies are 100 times more numerous than their more massive cousins, they are 100 times fainter than galaxies detected in previous deep - field surveys of the early universe, and normally too faint for Hubble to see.

The study used data from the Baryon Oscillation Spectroscopic Survey, or BOSS, an Earth - based sky survey that captured light from about 1.5 million galaxies to study the universe's expansion and the patterned distribution of matter in the universe set in motion by the propagation of sound waves, or «baryonic acoustic oscillations,» rippling in the early uniSurvey, or BOSS, an Earth - based sky survey that captured light from about 1.5 million galaxies to study the universe's expansion and the patterned distribution of matter in the universe set in motion by the propagation of sound waves, or «baryonic acoustic oscillations,» rippling in the early unisurvey that captured light from about 1.5 million galaxies to study the universe's expansion and the patterned distribution of matter in the universe set in motion by the propagation of sound waves, or «baryonic acoustic oscillations,» rippling in the early universe.

The goal of the survey is to study the stellar, gaseous, and blackhole content of galaxies at this important era in the history of the universe.

This plot shows over one and a half million of the brightest stars and galaxies in the nearby universe detected by the Two Micron All Sky Survey (2MASS) in infrared light.

There is some recently reported evidence from surveys of over 15,000 galaxies that in one hemisphere of the universe more spiral galaxies are «left - handed», or rotating clockwise, while in the other hemisphere more are «right - handed», or rotating counterclockwise.
