As Stellar Observations Improve, Earth’s History and Future Get Fuzzier
Astronomers have gotten better at tracking the motions of stars just beyond the solar system. But that’s made it harder to predict Earth’s future and reconstruct its past.

How to Create a Black Hole Out of Thin Air
Black holes were thought to arise from the collapse of dead stars. But a Webb telescope image showing the early universe hints at an alternative pathway.
Back Then, Baby Galaxies. Next, a Super-Mega Galactic Cluster?
The Webb telescope has spotted some of the oldest known collections of stars. They may have a very bright future.
That Famous Black Hole Just Got Even Darker
Astronomers recently used artificial intelligence to fine-tune the first-ever image of a black hole, captured in 2019 by the Event Horizon Telescope.
The Milky Way’s Black Hole Comes to Light
The Event Horizon Telescope has once again caught sight of the “unseeable.”
Military Memo Adds to Possible Interstellar Meteor Mystery
The U.S. Space Command seemed to confirm a claim that a meteor from outside the solar system had entered Earth’s atmosphere, but other scientists and NASA are still not convinced.
The Most Intimate Portrait Yet of a Black Hole
Two years of analyzing the polarized light from a galaxy’s giant black hole has given scientists a glimpse at how quasars might arise.
