Webb Telescope Reveals Surprising Details About Survivor Planet WD 1856 b

The James Webb Space Telescope has provided the first close-up look at WD 1856 b, a Jupiter-sized planet orbiting a white dwarf. The planet's unusual orbit and high temperature suggest it survived its star's death through gravitational interactions, challenging existing models of stellar evolution.

Earth's Frame Dragging Measured with Unprecedented Accuracy

Astronomers led by Ignazio Ciufolini have achieved the most accurate measurement of Earth's frame dragging (Lense-Thirring effect) to date, reducing uncertainty to 0.2%. Using the LARES-2 satellite and ground-based lasers, they overcame challenges like Earth's oblateness and lunar/solar tides.

Komodo Dragons, Not Hobbits, Likely Hunted Dwarf Elephants on Flores

New research suggests Komodo dragons, not Homo floresiensis (Hobbits), hunted dwarf elephants on Flores. Evidence of Komodo dragon teeth marks on Stegodon bones, alongside stone tool marks, indicates Hobbits likely scavenged leftovers. This challenges previous assumptions about Hobbit hunting capabilities and their evolutionary origins.

French Scientists Uncover Rapid Seafloor Spreading Events

French scientists used underwater monitoring stations to observe a major seafloor spreading event on the Australian-Antarctic plate boundary. Data revealed rapid crust formation, magma reservoir drainage, and significant seafloor uplift, with some events occurring without obvious seismic activity, suggesting current seismic monitoring may miss crucial processes.
