SPACE & PLANETS ARCHIVE
Auroral Structure Could Be Caused by Bouncing Electrons
High-resolution optical observations of aurorae show fluctuations and structuring that could be explained by interactions between electrons and a plasma phenomenon called Alfvén waves.
What We Could Lose by Trying to Make Mars Habitable
The rock, ice, and atmosphere of Mars hold a largely unread archive. Terraforming could erase it before the biggest scientific questions are answered.
NASA has Underspent on Research and Analysis for 15 Years
Spending for NASA’s research and analysis programs has remained relatively flat for 15 years, ignoring recommendations from community-led decadal surveys and directives by Congress.
Chariklo’s Rings Are Evolving
One ring became more opaque, and the other became more translucent. Astronomers don’t know why.
Presumed Role of Chorus Waves Out of Tune with New Data
Distinctive plasma ripples are thought to play a big role in electron loss from Earth’s radiation belts, but a new study suggests a more limited influence.
Of Cosmic Rains and Delayed Trains
Scientific detective work corrected the date of an early disruption in telegraph service, solidifying the links between solar weather and technological disturbances.
Venusian Sulfur Clouds Might Not Be So Inhospitable After All
New research shows that peptides can fold into “omega loops” linked to biological functions, even in highly acidic environments.
How the 2024 Solar Superstorm Drained Earth’s Radiation Belt
Researchers dig into storm processes linked to dramatic electron loss from the outer Van Allen belt.
Sharpest-Ever Image of the Sun Shows Small but Mighty Swirls
These tiny instabilities could play an outsized role in energizing the Sun’s corona.
The Economic Costs of Solar Storms
Though less present in the public consciousness than hurricanes and wildfires, space weather represents a real and potentially significant threat to society.
