New images of the interstellar object 3I/ATLAS indicate that the comet may be erupting in multiple ice volcanoes as it travels through the inner solar system. The eruptions appear to release gas, dust and frozen material from beneath the surface.
The findings were presented in a study posted to arXiv and mark one of the most detailed attempts to understand the behaviour of an object older than the Sun itself. The material jets observed around the comet resemble those seen on icy dwarf planets and frozen moons orbiting beyond Neptune, which strengthens interest in the comet's origins.
