Magnetized particles in a meteorite suggest strong magnetic fields in the early solar nebula.
Trapped ions discovered at midlatitudes can have energies exceeding 100 megaelectron volts per nucleon. Their detection adds to our understanding of the powerful radiation environment around Jupiter.
Meteorite isotopes, meteorite paleomagnetics, and planet formation models collectively show Jupiter formation via first slow then fast collection of material by core accretion in <5 million years.
Chemical compositions of rocks from Mars indicate that the earliest orbits of Jupiter and Saturn were more circular than they are today.
Wind has been one of the most robust, diverse, long-lasting, and impactful heliophysics missions ever to have been carried out.
Juno spacecraft observations provide the first global description of dawn storms in Jupiter’s aurorae, from their initiation to their end.
Another first from NASA’s Juno spacecraft: the detection of Jupiter radio emissions influenced by the moon Ganymede, over a range of about 250 kilometers in the polar region of Jupiter.
Not all planets move the needle. But whatever planet you take a magnetic compass to, it’s sure to point out clues to secrets underfoot.
A new tool to measure the magnetic signatures of big meteorites could not only aid NASA’s mission to Psyche; it could also help solve mysteries about how magnetic fields formed in our early solar system.
Meteorite NWA 11004 contains evidence of melting preceding an impact dated to 4546±36 Ma. Short lived radioactive decay had already heated the parent body of this meteorite before the impact.
