Galaxies don't simply feed their central supermassive black holes, but the activity generated inside affects the entire galaxy and more.

If our Milky Way were located in the Virgo cluster instead of the Local Group, chances are we'd already be a "red and dead" galaxy.
In 2022, Hubble owned the record for most distant galaxy. Today, that galaxy is down to the 9th most distant object. Thanks, JWST.
How does star-formation, occurring in small regions within galaxies, affect the entire host galaxy that contains it? JWST holds the answers.
With no other galaxies in its vicinity for ~100 million light-years in all directions, it's as isolated and lonely as a galaxy can be.
The space telescope's findings challenge the notion of a galaxy brimming with life.
Almost every large structure in the Universe displays a 5:1 dark matter-to-normal matter ratio. Here's how some galaxies defy that rule.
Our own galaxy, the Milky Way, is both completely normal and absolutely remarkable in a number of ways. Here's the story of our cosmic home.
Stars are born, live, and die within the spiral arms of galaxies like the Milky Way. These 19 JWST spirals deliver unprecedented riches.
Even after the first stars form, those overdense regions gravitationally attract matter and also merge. Here's how they grow into galaxies.
Finding it at all was a happy accident. Examining it further may help unlock the secrets hiding within the earliest galaxies of all.
Given enough time, all galaxies will expel their star-forming material and wind up dead. Is this the earliest one, or is it just asleep?
With so many early galaxies of unexpectedly large brightnesses, JWST surprised us all. Here's how scientists made sense of what we see.
Beyond the planets, stars, and Milky Way lie ultra-distant objects: galaxies and quasars. Here's how far back we've seen throughout history.
The biggest, brightest galaxies are the easiest to spot, but the tiniest ones teach us about how the Milky Way assembled and grew up!
On the largest cosmic scales, galaxies line up along filaments, with great clusters forming at their intersection. Here's how it took shape.
JWST has puzzled astronomers by revealing large, bright, massive early galaxies. But the littlest ones pack the greatest cosmic punch.
In 1924, Edwin Hubble found proof that the Milky Way isn't the only galaxy in the Universe.
Your life’s memories could, in principle, be stored in the universe’s structure.
Because of dark energy, distant objects speed away from us faster and faster as time goes on. How long before every galaxy is out of reach?
The Big Bang theory is not threatened, but astrophysicists have some explaining to do.
The Universe is an amazing place. Under the incredible, infrared gaze of JWST, it's coming into focus better than ever before.
Named "Supernova H0pe," it shows how JWST plus gravitational lensing can be used to solve the greatest puzzle facing astronomy today.
Today, the star-formation rate across the Universe is a mere trickle: just 3% of what it was at its peak. Here's what it was like back then.
Early on, only matter and radiation were important for the expanding Universe. After a few billion years, dark energy changed everything.
A more distant galaxy liked the lens so much that it went and put a ring on it. Here's the science behind this remarkable cosmic object.
From the present day all the way to less than 400 million years after the Big Bang, we're seeing how the Universe grew up like never before.
From when its light was emitted, the El Gordo galaxy cluster might be the most massive object in all of existence. Here's how JWST sees it.
NASA’s Michelle Thaller explains what happens when the densest stars in the galaxy collide.

With hundreds of billions of stars burning bright, some galaxies are already dead. Their inhabitants might not know it, but we're certain.
