NASA Ends the Swift Mission After Nearly 22 Years as Its Orbit Decays and Re-Entry Looms
Swift saw over 2,000 gamma-ray bursts and fed some 7,000 papers; drag from a more active Sun pulled it down to 275 km, where its telescopes could no longer hold steady, and NASA stopped science.

Houseplants Do Not Purify Your Air, and the Real Reason to Keep Them Is Better Than the Myth
A 1989 NASA experiment in sealed chambers became the most repeated claim in interior décor. In an actual room, ventilation removes pollutants far faster than plants can, and you would need an implausible indoor forest to compete.

Saturn Has Grown a Ten-Sided Storm at Its South Pole, and Nobody Saw It Start
Hubble has confirmed a decagon riding a jet stream around Saturn's south pole, each side longer than Earth is wide. The northern hexagon has been there for forty years. This one was not there in 2022.

An Amateur Astronomer Scouting a Quebec Campsite Led Scientists to a 390-Million-Year-Old Impact Crater
Joel Lapointe spotted an odd circular feature on satellite maps while planning a trip near Lake Marsal in 2024, and the tip led researchers to confirm a 25-kilometre impact structure now named Uhackatik.

The Telescope Launching This Month Sees a Patch of Sky a Hundred Times Wider Than Hubble's
Nancy Grace Roman is not a bigger Webb. It is a survey instrument, built to photograph enormous areas of sky at Hubble-class sharpness, and its value is in the sheer volume of what it will record.

Giant Canyon on Mars Is Still Tectonically Active, Study of a 2021 Marsquake Finds
Re-reading a quake NASA's InSight lander recorded in 2021, researchers place it in an ancient fault under Valles Marineris and say the planet's crust still breaks along old scars.

Cassini's Old Data Just Showed How Enceladus Sorts Its Ocean Chemistry Into Different Ice Grains
A reanalysis of nearly a thousand ice grain spectra from Saturn's icy moon found that freezing droplets separate salts into distinct pockets, a sorting process that could make it far easier for a future probe to detect organic chemistry from its hidden ocean.
