Huge New Storm Creates Hexagon at Jupiter’s South Pole

SAN FRANCISCO — NASA’s Juno probe discovered a giant new storm swirling near Jupiter’s south pole last month, a few weeks after pulling off a dramatic death-dodging maneuver. Juno spied the newfound maelstrom, which is about as wide as Texas, on Nov. 3, during its most recent close flyby of Jupiter. The storm joins a […]

First-of-Its-Kind Neutron Star Flashes Bizarre ‘Cyclotron Line’ at Earth

A twisted little neutron star devoured chunks of its stellar twin, revealing a never-before-seen phenomenon to scientists watching on Earth. Unlike most objects in space (including other neutron stars and planet Earth), neutron star GRO J2058+42 doesn’t have two simple magnetic poles at its north and south ends. Instead, it has a distorted magnetic field, […]

We aren’t sure how tiny particles come together to build baby planets, but dropping glass beads from the top of a tall tower has shown that it may be with some help from static electricity. The very first seeds of planets are made of […]

The Universe Remembers Gravitational Waves — And We Can Find Them

Gravitational waves slosh throughout the universe as ripples in space-time produced by some of the most cataclysmic events possible. With facilities like the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo, we can now detect the strongest of those ripples as they wash over the Earth. But gravitational waves leave behind a memory — a permanent […]
