The cosmic superstructure Quipu is more than 13,000 times the length of the Milky Way, and its mass is 200 quadrillion times ...

Newly discovered Quipu, a superstructure in which galaxies group together in clusters and clusters of clusters, is the ...

Enormous Galaxy Clusters Found to be 1.3 Billion Light-Years Wide, Deemed to be The Largest Known Structure In a monumental ...

In 1920, astronomers Harlow Shapley and Heber Curtis held a Great Debate. Shapley argued that the spiral nebulae were small and in the Milky Way, while Curtis took a more radical position that they ...

"They're so rare, and they're incredibly useful scientifically," said Conor O'Riordan of the Max Planck Institute for ...

Little red dot galaxies owe some of their coloration to a phenomenon called "redshift." As light from a galaxy travels toward Earth, the expansion of the universe stretches its wavelength ...

It's all thanks to multi-object spectroscopy, which measures the redshift of these galaxies, and hence the distance to them in an expanding universe, in an observed volume of space. With such ...

An international team of researchers has found dark matter dominating the halos of two supermassive black holes in galaxies ...

For six years, the 6dF Galaxy Survey (6dFGS) collected 136,304 spectra, including redshift data for 125,071 galaxies up to two billion light years away. The combination of these distance ...
