Do Earth-like Exoplanets Have Magnetic Fields? Far-off Radio Signal Is Promising Sign
Earth’s magnetic field does more than keep everyone’s compass needles pointed in the same direction. It also helps preserve Earth’s sliver of life-sustaining atmosphere by deflecting high energy particles and […]

Two Of Uranus’ Moons May Harbor Active Oceans, Radiation Data Suggests News Releases
Uranus — the turquoise, tilted oddball of the solar system — may have just joined ranks with Jupiter, Saturn and Neptune as host to at least one icy moon that’s […]

Multiverse Predictions For Habitability: Stellar And Atmospheric Habitability
Stellar activity and planetary atmospheric properties have the potential to strongly influence habitability. To date, neither have been adequately studied in the multiverse context, so there has been no assessment […]

The Crucial Role Of Surface Magnetic Fields For Stellar Dynamos: Epsilon Eridani, 61 Cygni A, and the Sun
Cool main-sequence stars, such as the Sun, have magnetic fields which are generated by an internal dynamo mechanism. In the Sun, the dynamo mechanism produces a balance between the amounts […]

Revisiting the Biological Ramifications of Variations in Earth's Magnetic Field
An Earth-like planetary magnetic field has been widely invoked as a requirement for habitability as it purportedly mitigates the fluxes of ionizing radiation reaching the surface and the escape of […]

Magnetic Fields of Extrasolar Planets: Planetary Interiors and Habitability
Jupiter’s radio emission has been linked to its planetary-scale magnetic field, and spacecraft investigations have revealed that most planets, and some moons, have or had a global magnetic field. Generated […]

Magnetic Field Was Critical for Life on the Early Earth
Nearly four billion years ago, life arose on Earth. Life appeared because our planet had a rocky surface, liquid water, and a blanketing atmosphere. But life thrived thanks to another […]

Using Radio Waves to Detect Exomoons
Scientists hunting for life beyond Earth have discovered more than 1,800 planets outside our solar system, or exoplanets, in recent years, but so far, no one has been able to […]
