How El Niño Creates a Cascade of Tropical Fires
See how El Niño shifts drought and fire risk across the tropics, why the Amazon can burn, and how satellites reveal hidden fires.
How the Treble Clef Galaxy Cluster Revived a Faded Radio Signal
A black hole outburst faded, then a galaxy-cluster collision brought its radio glow back. See how astronomers reconstructed the Treble Clef.
How Batteries Can Survive the Moon’s Extreme Cold
NASA’s SPEARS cells survived deep cold and worked after warming. See how solid electrolytes could power tools and rovers near the lunar South Pole.
What Brown Dwarfs Reveal About the Line Between Stars and Planets
See how SPHEREx reads brown dwarf atmospheres, why clouds challenge current models, and what these objects teach us about giant exoplanets.
Why Thawing Permafrost Makes the Ground Collapse
Permafrost can contain more ice than soil. See how thaw creates thermokarst, reshaping water, ecosystems, and Arctic communities.
How Scientists Link Extreme Weather to Climate Change
See how event attribution compares real and counterfactual climates to measure whether warming changed an extreme event’s odds or intensity.
How Spacecraft Heat Shields Survive Atmospheric Reentry
See how blunt shapes, ablative materials, and deployable aeroshells protect spacecraft from the extreme heat of atmospheric reentry.
What the Farthest Fast Radio Burst Reveals About Its Source
Webb traced the farthest known fast radio burst to a tiny young galaxy, strengthening the magnetar case and mapping matter along the way.
How Engineers Test a Spacecraft Before Launch
Spacecraft are shaken, blasted with sound, heated, chilled, and checked for interference before launch. See what each test reveals.
Why Chocolate Turns White: Fat Bloom vs. Sugar Bloom
That pale film on chocolate is usually fat or sugar bloom. See what causes each type, whether it is safe, and how proper storage prevents it.
Why Acoustic Foam Does Not Soundproof a Room
Acoustic foam reduces echo, but soundproofing blocks transmission. See how gaps, mass, decoupling, STC, and NRC shape quieter rooms.
Why NASA Studies Antibiotic-Resistant Bacteria in Space
