This story was provided by Live Science, a sister site of Space.com. Astronomers have discovered over a dozen “dormant” galaxies that paused their star formation within the first billion years after the Big Bang. The discovery, made with data from the James Webb Space Telescope (JWST), illuminates a fascinating phase in the lives of early galaxies and could provide more …

A distant galaxy appears to have more than a dozen tightly packed star-forming clumps arranged like a bunch of grapes — far more than astronomers thought possible in a galaxy from the early universe. The galaxy, nicknamed “Cosmic Grapes,” is believed to have formed just 930 million years after the Big Bang. A new study has revealed that the galaxy …

Quick facts What it is: The Hubble Ultra Deep Field, revisited by the James Webb Space Telescope Where it is: Close to the Big Dipper in the night sky When it was shared: Aug. 1, 2025 The James Webb Space Telescope‘s (JWST) latest extragalactic survey has revealed fainter and more distant objects than ever before, some dating back to the …

Just as ocean waves shape our shores, ripples in space-time may have once set the Universe on an evolutionary path that led to the cosmos as we see it today. A new theory suggests gravitational waves – rather than hypothetical particles called inflatons – drove the Universe’s early expansion, and the redistribution of matter therein. “For decades, we have tried …

A team of astronomers says it has identified the most distant black hole ever confirmed — a cosmic heavyweight that formed just 500 million years after the Big Bang, when the universe was only about 3% of its current age. The discovery sets a new benchmark for how early supermassive black holes can form and raises questions about their origin …

The first stars in the universe may have been much smaller than we thought, new research hints — possibly explaining why it’s so hard to find evidence they ever existed. According to the new research, the earliest generation of stars had a difficult history. These stars came to be in a violent environment: inside a huge gas cloud whipping with …

Since conventional explanations have failed to pony up dark matter, one physicist is looking towards the unconventional. In a series of two papers, physicist Stefano Profumo of the University of California, Santa Cruz has proposed two strange, but not impossible, origins for the mystery material responsible for the excess gravitational effects we see out there in the Universe. In the …

Scientists from the University of Hawaii’s Institute for Astronomy (IfA) have discovered the most energetic cosmic explosions since the Big Bang. Extreme nuclear transients (ENTs) occur when massive stars several times larger than our Sun are torn apart by supermassive black holes. ENTs shine with intense luminosity, much brighter than supernovae, which originate from the violent death of massive stars. …

A new paper has predicted that the universe’s expected lifespan is drastically shorter than once thought — and that the cosmos will start to die in just 10 billion years. This is only one possible theory, however, and nobody really knows when the universe will end. There are two leading theories for how the universe may die: the “Big Freeze” …
