Astronomers discovered remnants of a dwarf galaxy our Milky Way devoured 10 billion years ago, offering new clues about how our cosmic home grew from a smaller galaxy into the massive spiral we call home today.
The James Webb Space Telescope is discovering fully formed galaxies just hundreds of millions of years after the Big Bang, forcing scientists to rethink how quickly the universe evolved. Instead of finding cosmic "villages," astronomers are spotting ancient "megacities" that challenge everything we thought we knew about the early universe.
The James Webb Space Telescope keeps finding massive, bright galaxies that shouldn't exist yet according to our current understanding of the universe's age. One physicist's peer-reviewed theory suggests a radical explanation: the universe might be twice as old as we thought.
The James Webb Space Telescope is discovering ancient galaxies that are forcing scientists to rethink how the early universe worked. These cosmic overachievers are revealing that our understanding of the first billion years after the Big Bang needs a major upgrade.
Astronomers using the James Webb Space Telescope have discovered a tiny ancient galaxy that may contain remains from the universe's very first stars. These cosmic giants created the building blocks for everything we see today, including life itself.
Astronomers found a breakthrough clue to explain mysterious red dots spotted in deep space, revealing how supermassive black holes formed in our universe's infancy. The discovery connects puzzle pieces that have baffled scientists since Webb started sending back images.
Scientists developed an AI system that's 95% better at detecting how the universe is changing, potentially revealing gaps in our cosmic understanding. The breakthrough could help solve some of astronomy's biggest mysteries.
Theoretical physicist Chanda Prescod-Weinstein's new book proves that understanding the universe doesn't require intimidating equations. She weaves together pop culture, poetry, and cosmology to make the deepest questions in physics accessible to everyone.
Astronomers have finally mapped a massive cosmic structure that's been hiding behind our own galaxy for billions of years. The Vela Supercluster spans 300 million light-years and contains the mass of 30 quadrillion suns.
After ten years of work, astronomers built a computer simulation of the entire universe that looks remarkably like the real thing. The breakthrough confirms our understanding of how galaxies form is even better than we thought.
What if the Big Bang wasn't the beginning of everything? Scientists now believe ancient black holes might be "cosmic fossils" from a universe that existed before ours.
Strange red lights in the young universe puzzled astronomers for years, but new research reveals they're young black holes wrapped in dense gas clouds, not impossibly massive galaxies. The discovery rewrites our understanding of how supermassive black holes grew in the early cosmos.
New research just reopened one of cosmology's biggest questions: what shape is our universe? Possibilities once thought impossible are now back in play.
Astronomers discovered a rare supernova from 10 billion years ago whose light was bent into multiple images by a galaxy's gravity, creating a cosmic time machine that could solve one of science's biggest mysteries. This discovery might finally explain dark energy, the mysterious force pushing our universe to expand faster and faster.
Researchers discovered how to use gravitational waves to solve one of physics' biggest mysteries: why we get different answers when measuring how fast the universe is growing. This breakthrough could finally end the decade-long "Hubble tension" debate.
A telescope launched in 1989 proved how the universe began and revealed the cosmic seeds that made galaxies, stars, and us possible. The discovery was so groundbreaking it earned a Nobel Prize and launched the era of precision cosmology.
The James Webb Space Telescope discovered mysterious bright red objects from the early Universe that shouldn't exist according to standard physics. Scientists just figured out they're a new type of black hole that formed directly from gas clouds, solving a cosmic puzzle.

Scientists just witnessed the earliest gathering of galaxies ever seen, forming when the universe was barely a billion years old. The discovery suggests our cosmic neighborhood came together much faster than anyone predicted.
Scientists discovered our galaxy rests on a massive, flat sheet of dark matter stretching 30 million light-years across. The finding solves a decades-old puzzle about why nearby galaxies move differently than expected.
The largest cosmic map ever created shows the universe isn't forming galaxy clusters as densely as scientists predicted, revealing an exciting puzzle in our understanding of how everything came to be.
