Astronomers have directly linked the supermassive black hole M87* to its enormous plasma jet using new Event Horizon Telescope data. The findings reveal where the jet originates near the black hole’s shadow, providing crucial insight into how black holes launch matter at nearly the speed of light.

Scientists studying archival Galileo spacecraft data have identified ammonia-bearing compounds on Europa for the first time. The ammonia appears along surface cracks, indicating recent transport from the moon’s subsurface ocean. Because ammonia contains nitrogen and degrades quickly under radiation, its presence strengthens Europa’s status as a promising target in...
