Researchers using the JWST may have found evidence of the Universe’s first stars. Called Population III stars, they were massive and hot.

NASA’s Juno spacecraft recently spotted a glassy-smooth lava lake amid the volcanic hellscape of Jupiter’s moon Io.

When Juno’s orbit swooped past Io last December, its cameras captured a mirrorlike reflection from a small patch of the moon’s surface. The strangely shiny landmark turns out to be a lava lake, covered with a thin crust of smooth, gleaming volcanic rock. The rock was probably something like obsidian, a natural glass that forms from cooling magma here on Earth. Known as Loki Patera, the lava lake stretches 127 miles long and is dotted with rocky islands, and its edges glow with heat from the molten magma just beneath the surface.

Loki Patera isn’t the first lava lake scientists have spotted on Io; previous spacecraft, including Galileo (RIP) have also sent home images of similar features, but Juno’s pics are the clearest and most detailed. Based on Juno’s data, NASA created this animation of what a flight over Loki Patera might look like.

Researchers using Murriyang, CSIRO’s Parkes radio telescope, have detected unusual radio pulses from a previously dormant star with a powerful magnetic field.

New results published today in Nature Astronomy describe radio signals from magnetar XTE J1810-197 behaving in complex ways.

Magnetars are a type of neutron star and the strongest magnets in the Universe. At roughly 8,000 light years away, this magnetar is also the closest known to Earth.

Gravitics, which develops modules for commercial space stations, will work on tactically responsive space applications for the U.S. Space Force.

Solar Cycle 25 is about to hit its peak, making this an important time to increase space weather monitoring.
