Hints of Life on Exoplanet K2-18b Recede Even Further
New observations fail to confirm signs of life in the atmosphere of the distant planet K2-18b. They also raise questions about what it will take to detect biology light-years away.
Scientific Dreams in the Balance
Research breakthroughs are often sagas of passion, curiosity and sacrifice. If Trump’s proposed budget cuts for 2026 are enacted, many such journeys may never get started.

New Studies Dismiss Signs of Life on Distant Planet
In April, astronomers said they had detected a possible signature of life on the exoplanet K2-18b. Now, three independent analyses discount the evidence.
Astronomers Detect a Signature of Life on a Distant Planet
Further studies are needed to determine whether K2-18b, which orbits a star 120 light-years away, is inhabited, or even habitable.
Chandra Observatory Captures Two Supernovas in (Slow) Motion
For the 25th anniversary of the Chandra X-ray Observatory, NASA produced ghostly time-lapse videos of two centuries-old stellar explosions.
Piping Up at the Gates of Dawn
Astronomers have found the earliest and most distant galaxy yet.
Galaxies in the Early Universe Were Shaped Like Bananas, Study Suggests
Images from the Webb telescope suggest that newborn galaxies look weirder than expected. Exactly how screwy was physics at the dawn of time?
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.
