JWST Caught a Hidden Galaxy Like Our Own Growing at The Dawn of Time

The gigantic galaxies we see in the Universe today, including our own Milky Way galaxy, started out far smaller.

Astronomers report oscillation of our giant, gaseous neighbor

A few years ago, astronomers uncovered one of the Milky Way's greatest secrets: an enormous, wave-shaped chain of gaseous clouds in our sun's backyard, giving birth to clusters of stars along the spiral arm of the our galaxy.

JWST Reveals a Surprise Twist in Black Hole And Galaxy Formation

The beginning of the Universe has always been something of a chicken-and-egg problem. Did stars and galaxies form first, with black holes slowly coalescing in their midst? Or did black holes appear before the first galaxies?

NASA's Webb Depicts Staggering Structure in 19 Nearby Spiral Galaxies

It’s oh-so-easy to be absolutely mesmerized by these spiral galaxies. Follow their clearly defined arms, which are brimming with stars, to their centers, where there may be old star clusters and – sometimes – active supermassive black holes.

Incredible galaxy with no visible stars discovered by accident

To this point, J0613+52 is unlike any other galaxy discovered in the universe. What we do know is that it’s an incredibly gas rich galaxy and its not demonstrating any star formation.

Discovery of 'Big Ring on the Sky' structure

The latest discovery of an ultra-large structure called the "Big Ring" adds to "mounting evidence" that challenges what we know about the universe.

Astronomers Solve the Mystery of Giant Radio Circles

The circles could be  shells created by outflowing galactic winds, maybe from massive supernovae explosions. These extremely quick outflowing winds can be produced by massive “starburst” galaxies

Oversized Ancient Galaxy Isn't What Astronomers First Thought

Discovered in 2013 as the source of rampant star formation just 880 million years after the Big Bang, a 'galaxy' named HFLS3 is not a galaxy at all. HFLS3 is actually six galaxies undergoing an epic, giant collision at the dawn of time.

Astronomers find life ingredient at galaxy's edges

The discovery of phosphorus in a molecular cloud at the edge of the Milky Way galaxy extends the presence of the element almost twice as far out as where it was known to exist.

JWST Has Found A Young Galaxy With A Surprising Amount of Metals

Astrophysicists working with the James Webb Space Telescope (JWST) have found a surprising amount of metal in a galaxy only 350 million years after the Big Bang.

Webb Telescope Spots the Second Most Distant Galaxy Yet

A recent deep field image from the Webb Space Telescope features two galaxies. These galaxies are remarkable for their distance from Earth, being the second and fourth most distant galaxies ever observed.

Our Galaxy's Heart Is Pulsing With a Mysterious Signal

Every 76 minutes, like clockwork, the gamma-ray flux of Sagittarius A*, the supermassive black hole in our galaxy, fluctuates, suggesting an orbital motion of something whirling madly around the black hole.

Australian Radio Telescope Spots Possible "Polar Ring" Galaxy

A radio telescope in Australia recently captured a stunning image of NGC 4632, a galaxy some 56 million light-years from Earth. The image reveals a halo of cool hydrogen orbiting perpendicular to the galaxy itself.

Mysterious Black Hole Twins May Fuel The Brightest Galaxies in Space

According to a new analysis of a type of galaxy known as a blazar, the best explanation for unusual changes in their glow is a pair of supermassive black holes locked in a decaying orbit.

Most distant galactic magnetic field yet

Astronomers detected the most distant galactic magnetic field so far. The galaxy is called 9io9. Its light has to travel travel more than 11 billion years to reach us, from a time when the universe was a young 2.5 billion years old.
