For the first time, scientists used the combined power of NASA's Hubble and James Webb Space Telescopes to study some of the most far-flung bodies in our solar system, trans-Neptunian objects (TNOs). Some are the smallest ...

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 ...
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 ...

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 ...
When two black holes crash together and merge, the newly formed black hole rings like a bell, sending out gravitational waves with specific frequencies that fade over time. This brief, fading pattern of waves is called ringdown, ...

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.
There are nearly 1 million pieces of debris larger than 1 centimeter (0.4 inch) in near-Earth orbit. As we continue launching spacecraft and telescopes to explore the universe, this debris poses a significant threat of high-speed ...
