Rayos Planetarios: Misma Física, Mundos Distantes
Un rayo en el planeta Tierra necesita sólo algunos simples ingredientes para generar una chispa. Esos ingredientes existen en todo el sistema solar y más allá.
“Mushballs” May Drive Ammonia Transport on Jupiter
Hail might account for observed depletions of ammonia in the planet’s atmosphere.
New Energetic Neutral Atom Emissions from Jupiter, Io, and Europa
The first Jovian off-equator Energetic Neutral Atom viewings reveal distinct emissions from Jupiter and the orbits of Io and Europa: Energetic particle injections surprisingly occur inside Io’s orbit.
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.
Using Earth’s Atmosphere as a Solar Flare Monitor
Measurements of very-low frequency radio signal phase and amplitude can detect upper atmosphere changes caused by solar flares, enabling us to monitor flare occurrence and intensity.
Using a Machine to Help Us Learn About Jupiter’s Aurora
A first usage of principal component analysis on Hubble images of Jupiter’s auroral ovals reveals the most common patterns, and machine learning classification reveals their physical causes.
Voyager 2’s Interstellar Arrival Was Kind of Familiar. That’s Surprising
The spacecraft crossed the solar system’s edge at a different spot and in a different solar season than Voyager 1. Nevertheless, the border looked much the same in both spots.
What Inflates the Solar Bubble? Voyagers Count What’s Missing
The first in situ measurement of the pressure at the edge of the solar system reveals that there’s still a lot we don’t know about what sets the size of the heliosphere.
Our Seismic Solar System
Earth’s not the only thing that shakes and quakes and goes around the Sun. Not by a long shot.
