During the 1970s, while probing distant galaxies to determine their mass, size, and other characteristics, astronomers noticed something interesting. When…
Is it possible to understand the Universe without understanding the largest structures that reside in it? In principle, not likely.…
A galactic merger is a chaotic event. When two massive structures like galaxies merge, their powerful gravitational forces wrench stars…
Gas is the stuff of star formation, and most galaxies have enough gas in their budget to form some stars.…
The Andromeda galaxy is our closest galactic neighbour, barring dwarf galaxies that are gravitationally bound to the Milky Way. When…
One of the most exciting developments in modern astronomy is how astronomers can now observe and study the earliest galaxies…
When a new space telescope is launched, it's designed to address specific issues in astronomy and provide critical answers to…
It's nearly impossible to identify individual stars billions of light years away. But thanks to gravitational lensing, astronomers have identified…
Astronomers have spent decades trying to understand how galaxies grow so large. One piece of the puzzle is spheroids, also…
Astronomers have used JWST to weigh a galaxy in the early Universe, finding that it has roughly the same mass…
