James Webb Telescope Captures Stunning Infrared View of Exposed Cranium Nebula

NASA’s James Webb Space Telescope has captured remarkably detailed infrared images of PMR 1, known as the “Exposed Cranium,” a planetary nebula roughly 5,000 light-years away in the constellation Vela. The observations reveal a glowing inner “brain” region surrounded by a hydrogen gas shell, divided by a dark lane of ejected material, providing fresh insight...

Astronomers Find ‘Impossible’ Galaxy ACDG-2 With Virtually No Stars and a Massive Dark Matter Core

Astronomers have identified CDG-2, a faint galaxy in the Perseus cluster that appears to be composed almost entirely of dark matter. Located 300 million light-years from Earth, it was discovered by tracking globular star clusters using data from Hubble, Euclid, and Subaru telescopes. Scientists estimate that about 99% of its total mass is dark matter.
