No Magma Ocean For Io, Jupiter’s Volcano-Covered Moon
Io, the innermost of Jupiter’s four largest Galilean moons, is covered with hundreds of volcanoes, some shooting lava fountains dozens of miles high. But what kind of interior could drive this magma fury? After NASA’s Juno orbiter made two close flyovers of Io, planetary scientists now think they know. Ever…

The Clinton B. Ford Observatory, once used for variable star observations, has fallen to wildfires.
No Intermediate-Mass Black Hole for Omega Centauri?
Last month, astronomers discovered a giant black hole in Omega Centauri. But it might contain a swarm of stellar-mass black holes instead.
A Closer Look at a Potential "Eyeball Planet"
New James Webb Space Telescope observations of LHS 1140b hint at a temperate water world with a nitrogen-rich atmosphere.
Webb Telescope Reveals Parallel Jets from Baby Stars
A new image taken by the James Webb Space Telescope reveals a stunning alignment among the infant stars in the Serpens Nebula.
Spiral Galaxies May Be a Dime a Dozen in the Early Universe
A new study with data from the James Webb Space Telescope found that galaxies may have started forming spirals far earlier than astronomers previously thought.
