For years, scientists have relied primarily on radio imaging from techniques like very long baseline interferometry (VLBI) to study jets from the active galactic nuclei of supermassive black holes. This allows for the detection ...
Astronomers have taken one of the deepest looks yet at Cloud-9, a candidate "dark galaxy," and found no trace of stars. The paper outlining this discovery was posted to the arXiv preprint server on Aug. 21.
On a mostly flat plain an hour north of Stockholm lies a collection of large burial mounds dating from an ancient culture at least 2,500 years old. These people were not Vikings; they were northern Germanic Goths, pagan polytheists ...

Astronomers have found the first direct evidence that a wandering black hole can feed itself by dragging gas along in its wake as it moves through its galaxy. It's the first direct evidence of an accretion channel long predicted ...
New observations of the composition of distant galaxies offer insights into the earliest phases of the universe and confirm decades of scientific understanding of the elements and particles produced by the Big Bang, according ...

Toward the end of their lives, low-mass stars undergo an abrupt dip in brightness, also known as the luminosity bump. While the endpoint of this bump is well understood, its onset has remained elusive. Now, in a paper published ...

A few hundred million years after the Big Bang, the first stars ignited—literally the "let there be light" moment for the universe. Now known to astronomers as Population III, or Pop III, stars, these giants were very different ...
