Keck Observatory's KPIC instrument measured the spin of giant gas planets and brown dwarfs ('failed stars') using spectroscopy. In the HR 8799 system, the brown dwarf — more than three times heavier — rotates about six times slower than its lighter planetary neighbor. The likely culprit: a newborn planet's magnetic field braking against its birth disk, offering a new way to tell planets and stars apart.
Launch the best telescope in the world today, and you still can't photograph Jupiter as it looked a decade ago. Hubble, working since 1990, caught something no new instrument ever could: the outer winds of the Great Red Spot speeding up by as much as 8% between 2009 and 2020. SORABUMI explains why a telescope's worth isn't measured by how new it is, but by how long it has been watching.
On the evening of June 9, 2026, Venus and Jupiter will close to within 1.5 degrees of each other in the western sky. They'll look like neighbors, but the actual gap between them is hundreds of millions of kilometers. Here's what a conjunction really is, and how to make the most of it.
NASA's Juno spacecraft has captured detailed observations of Jovian lightning, confirming discharges with more than a million times the energy of Earth's. We look at 613 microwave pulses, the reason water behaves so differently in a hydrogen sky, and what the storm planet is still hiding.
Jupiter boasts four Galilean moons while Saturn's only large moon is Titan. A study published in April 2026 traced that striking difference to the planets' magnetic fields — an invisible barrier that determined which moons lived and which ones fell.
