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.
Scientists propose that dark matter-powered stars could explain three puzzling discoveries from the early universe, including mysterious supermassive black holes and ultra-bright galaxies that shouldn't exist. This breakthrough theory offers hope for understanding both the cosmos and dark matter itself.
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.
Scientists just finished mapping 669 million galaxies over six years, and the good news is our understanding of how the universe works passed the test. The Dark Energy Survey reveals our cosmic models are on track, even as they point toward exciting new mysteries to solve.
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.
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.
Scientists created the most detailed map of dark matter ever made, using 250,000 galaxies to reveal mysterious structures never seen before. This breakthrough could finally help us understand what makes up 85% of the universe's matter.
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 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.
