Magnetism disrupts winds on ‘hot Jupiter’ exoplanet
Simulations of HAT-P 7b’s magnetic field give clues to why the exoplanet’s winds blow both east and west.
- Planetary Science
Juno spacecraft reveals a more complex Jupiter
NASA’s Juno spacecraft has sent back unexpected details about Jupiter, giving scientists their first intimate look at the giant planet.

Watery exoplanet’s skies suggest unexpected origin story
Compared with Neptune, HAT-P-26b’s atmosphere has few heavy elements, suggesting it formed differently than the ice giants in Earth’s solar system.
- Planetary Science
Oxygen on comet 67P might not be ancient after all
Molecular oxygen detected around comet 67P may not be a relic of the solar system’s birth. Instead, it may be generated by interactions of water, the solar wind and the comet’s surface.
- Planetary Science
Mars may not have been born alongside the other rocky planets
Mars formed farther away from the sun than its present-day orbit, not near the other terrestrial planets, new research suggests.

Here’s how an asteroid impact would kill you
Most deaths caused by an asteroid impact would result from shock waves and winds generated from the blast, rather than effects such as earthquakes and tsunamis, new simulations show.
