Challenges to studying the ionosphere’s ability to conduct electrical currents undercut scientists’ efforts to improve space weather forecasting models. Let’s tackle them together.
Space & Planets
Scientists Float a New Theory on the Medusae Fossae Formation
Pumice-like rafts of lightweight material could have carried volcanic debris across an ancient Martian ocean to build one of the most puzzling features on the Red Planet.
Using Saturn’s Rings as a Seismometer
The Cassini spacecraft observed spiral density waves in the rings of Saturn which can be used to probe its interior structure and rotation.
The Closest Black Hole Is 1,000 Light-Years Away
An unseen object—probably a black hole—orbits with two normal stars in our cosmic neighborhood.
Space Weather Forecasting Takes Inspiration from Meteorology
Solar features analogous to major atmospheric waves on Earth could offer more advanced warning of harmful solar storms.
How Long Was Venus Habitable?
Climate simulations of Venus’s history could provide insights into the habitability of Earth and of exoplanets.
The Massive Ice Avalanches of Mars
Ice avalanches may have traveled at speeds of up to 80 meters per second.
Planetary Lightning: Same Physics, Distant Worlds
Lightning on Earth needs just a few simple ingredients to generate a spark. Those ingredients exist throughout the solar system and beyond.
Investigating the Spark
In May, we look at lightning—what it tells us about dangerous weather, how to find it on other planets, and what we might learn if we get all that data in one place.
How Fast Did an Ancient Martian Delta Form?
Terrestrial meander migration rates are used to estimate a formation timescale of decades for Jezero delta on Mars.
