The Flagship 2 simulation, developed using an algorithm by University of Zurich astrophysicist Joachim Stadel, is the largest ...

A University of Texas at Dallas physicist and his international colleagues in the Dark Energy Spectroscopic Instrument (DESI) collaboration are engaged in a multiyear data-gathering mission to try to ...

A growing list of dark star candidates could help explain why some early galaxies were so big, so early in the universe.

Physicists have been puzzling over conflicting observational results pertaining to the accelerating expansion rate of our Universe—a major discovery recognized by the 2011 Nobel Prize in Physics. New ...

The first stars in the universe formed out of pristine hydrogen and helium clouds, in the first few hundred million years after the Big Bang. New James Webb Space Telescope (JWST) observations reveal ...

The telescope aims to eventually chart one-third of the sky during its mission, capturing galaxies and stars. Scientists hope it will also shed light on the role of ...

It's hard to grasp the sheer amount of astronomical data that came online this week in a 1.6-petabyte data-dump from a Hawaiian telescope, but picture 30,000 Wikipedias or 15 Libraries of Congress. At ...

IDC has just released estimates that this year, the Digital Universe — meaning every electronically stored piece of data or file out there — will reach 1.2 million petabytes, or 1.2 zettabytes, this ...
