Did a Black Hole Form Before Its Galaxy? What Webb Actually Found
Webb measured a roughly 50-million-solar-mass black hole in the early universe with very little host-galaxy starlight. Here is what that does—and does not—mean.
RESEARCHWebb Found Brown Dwarfs Only Twice Jupiter’s Mass
In the IC 348 star-forming region, Webb found free-floating brown dwarfs around twice Jupiter’s mass—objects that push the boundary between stars and planets.
RESEARCHWebb Found Water and Dust Near the Milky Way’s Black Hole
Webb detected water and oxygen-rich dust around the aging star IRS 3, only about 0.55 light-years from Sagittarius A*. The location is extreme—but the water is not inside the black hole.
RESEARCHTiny Worlds Beyond Neptune May Preserve the Solar System’s First Memory
Hubble and Webb found very small trans-Neptunian objects whose colors still resemble larger members of their original populations, preserving clues to the early solar system.
RESEARCH3I/ATLAS: What We Learned From the Third Known Interstellar Visitor
3I/ATLAS came from beyond our solar system. Webb found unusual chemistry, including methane and carbon dioxide. Here is what the evidence shows.
RESEARCHAwake Inside a Dream: What Lucid Dreaming Actually Shows
Researchers have exchanged signals with sleeping dreamers. What does that reveal about the worlds we experience with our eyes closed?
SPECULATIVEIf Reality Is a Simulation, What Would Count as Evidence?
The famous simulation argument offers a conditional dilemma. It does not announce that someone has discovered the universe’s source code.
RESEARCHThe Star That Faded Away—and the Black Hole Question
N6946-BH1 faded from optical view. New research tests whether a failed supernova explains what remains.
RESEARCHA Cosmic Flash in a Millisecond: The Fast Radio Burst Mystery
An intense radio flash from a Galactic magnetar gave astronomers a concrete clue to one of the sky’s shortest-lived signals.
DOCUMENTEDThe Camera That Never Existed: Understanding AI Video
A convincing moving image can be created without a camera witnessing the scene. Here is how we separate creative possibility from evidence.
RESEARCHBefore You Believe the Impossible: A Video Verification Guide
A practical sequence for investigating an extraordinary clip: trace its origin, test its context, and name what remains unknown.
