Could Jupiter’s Heat Waves Help Solve a Planetary Energy Crisis?
Infrared observations reveal that Jupiter’s upper atmosphere is much warmer than models predict. The discovery may be a clue to finding missing heat sources in other giant planets.
Extremeness of Seasons Determined by Planetary Motion Parameters
We’ve long known that a planet’s orbital period and tilt determine length and intensity of seasons. We now see rotation rate matters too: max temperature shifts poleward as rotation slows.
Converging Toward Solutions to Grand Challenges
A hypothetical, space weather–induced power grid catastrophe served as a practice case for building unity and collaborative skills among disparate communities to address a major global hazard.
Isótopos de criptón proporcionan nuevos indicios sobre el pasado de los planetas
Para determinar cómo los elementos cruciales para el desarrollo de la vida llegaron a la Tierra, los científicos estudian los gases nobles. Actualmente, métodos mejorados traen consigo nuevos indicios a partir del criptón, el gas noble más enigmático.
Zipping Up Data to Zap It Back from an Icy Moon
NASA wants to send instruments to distant moons like Europa and Enceladus to search for life. But getting vital data back to Earth over limited bandwidth will take some impressive compression software.
Rare Meteorites Shed Light on Diamond Formation
By studying meteorites believed to be remnants of the catastrophic breakup of a dwarf planet, researchers are learning how lonsdaleite, a particularly hard type of diamond, forms in nature.
Space Raindrops Splashing on Earth’s Magnetic Umbrella
Though not as damaging as extreme space weather events, showers of plasma jets hit Earth’s magnetic shield every day—yet we’re only beginning to understand their effects.
Ozone, Water Vapor and Temperature: It’s a Complex Relation
Solar occultation observations from the ACS/MIR instrument provide coincident profiles of O3, H2O and temperature, shedding light on correlations and unveiling knowledge gaps in Mars’s photochemistry.
MESSENGER Reveals a More Dynamic Mercury Surface
Image pairs indicate that 99% of the planet’s surface could be altered in the next 25 million years.
Massive Stars May Commit Grand Theft Planet
New simulations show that planets around young, massive stars may have been captured or stolen rather than homegrown.
