Scientists May Have Solved Einstein's "Biggest Blunder
Physicists at Brown University discovered why the universe expands at a steady pace instead of spiraling out of control. The answer lies in the shape of space-time itself, which acts like a cosmic safety switch.
New AI Sees Universe Changes 95% Better Than Before
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.
Scientists May Know if Black Holes or Galaxies Came First
Astronomers are closer to solving one of space's biggest mysteries: whether black holes or galaxies formed first. New evidence suggests black holes might have been the cosmic pioneers.

Galaxies Clustered 12.8 Billion Years Ago, Earlier Than Thought
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 Find New Way to Measure Universe's Expansion
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.
James Webb Finds 'Red Monster' Galaxies in Early Universe
The James Webb Space Telescope discovered three massive galaxies that formed surprisingly early in the universe's history, challenging everything scientists thought they knew about how galaxies grow. These "red monsters" built stars twice as fast as current models predict was possible.
Scientists Create Synthetic Universe Matching Our Own
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.
James Webb Telescope Finds Galaxies That Rewrote The Rules
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.
Webb Telescope Maps Dark Matter in Stunning Detail
The James Webb Space Telescope just created the most detailed map ever of dark matter, the invisible substance that makes up most of our universe. Scientists can now see how galaxies formed across billions of years with twice the clarity of previous images.
10-Billion-Year-Old Supernova May Unlock Dark Energy Secret
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.
James Webb Telescope Maps Dark Matter Across the Universe
Scientists created the sharpest map ever of dark matter, the invisible substance that makes up 85% of everything in the universe. The breakthrough reveals how galaxies formed billions of years ago and confirms our best theories about how the cosmos works.
Astronomers Discover Supernova That Will Reappear in 60 Years
Scientists using the James Webb Space Telescope spotted a supernova whose light is taking multiple paths through space, with some images arriving now and others delayed by six decades. This cosmic phenomenon could finally help solve one of astronomy's biggest mysteries about how fast the universe is expanding.
James Webb Telescope Finds Ancient Galaxies That Shouldn't Exist
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.
NASA Satellite Unlocked Secrets of Universe's Birth
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.
Physicist Blends Star Trek and Science in New Book
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.
James Webb Telescope Spots Galaxy Holding First Stars Ever
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.
Scientists Find Black Holes May Predate the Big Bang
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.
Webb Telescope Maps Dark Matter's Role in Creating Life
Scientists used the James Webb Space Telescope to create the sharpest map yet of dark matter, revealing how this invisible force shaped the universe and made life possible. The breakthrough shows dark matter pulling ordinary matter together to form the first stars and galaxies.
Milky Way Sits on Giant Dark Matter Sheet, Study Finds
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.
