James Webb has spotted extremely distant galaxies formed soon after the Big Bang, but are they old or young? Or is this the wrong question to ask?
The astronomy and astrophysics decadal survey for the 2020s lays out plans to search for life on distant planets, understand the formation of galaxies and solve deep mysteries of physics.
Anyone with an internet connection can search the universe and possibly discover never-before-seen galaxies.
Despite the name, some black holes effectively “shine” as they suck up nearby material with such force that it begins to glow. New research reveals a new method for detecting these active black holes.
Plus, the tactics the food industry is using to boost sales of ultra-processed foods in middle-income countries. Listen to The Conversation Weekly.
More than 60 images capturing huge expanses of sky are sent to us from Chile. Within them we can see thousands of bright spots. What do we find when we look closer?
A galaxy 320 million light-years away has a surprisingly similar structure to the Milky Way, suggesting our galaxy isn’t as unique as it once seemed to astronomers.
The first ever Canadian-led large project on one of the world’s leading telescopes will investigate how the birth and death of galaxies are affected by their environment.
The Milky Way’s disc of stars becomes increasingly warped and twisted the further away they are from the galaxy’s centre.
Bigger galaxies tend to dominate the smaller, when the two collide. But the pending battle between our Milky Way and the Andromeda galaxy might be a much fairer fight than we previously thought.
The first reliable measure of the 3D shape of galaxies and their rotation helps to shed light on their history.
The recipe book for galaxy formation may need to be rewritten after the discovery of a massive galaxy that stopped making new stars early in the Universe’s history.
Understanding how the billions of stars in our galaxy formed and evolved is the subject of a huge galactic archaeology project.
A new discovery can help determine where all the stars in the universe’s galaxies actually come from.
Astronomers have taken a forensic approach to study the stellar halo of a galaxy to reveal hidden secrets on how such galaxies were formed.
Our universe’s most exciting days are well behind us, with new research showing the universe is now slowly but surely dying.
Meet the supermassive black hole that defied the model.
What happens to a galaxy when it runs out of the stuff needed to forge new stars?
Several dwarf galaxies have been discovered close to our own Milky Way and are adding to our understanding of how galaxies form. But why haven’t astronomers seen them before?
