A black hole is a region of spacetime exhibiting gravitational acceleration so strong that nothing can escape, not even light. These cosmic phenomena are said to form when massive stars collapse at the end of their life cycle. Then, they can continue to grow by absorbing mass from their surroundings, engulfing stars in their path and merging with other black holes.

ROME (AP) — The Stromboli volcano has erupted, spewing fiery chunks of lava onto the tiny Italian island and alarming residents and tourists.

The National Institute of Geophysics and Volcanology says a strong volcanic explosion just after noon Wednesday sent flaming lava rolling down the volcano’s slopes to the edge of the sea. A similarly spectacular eruption in July on Stromboli killed an Italian hiker.

There were no immediate reports of injuries. Some small fires were reported near one of the Mediterranean island’s hamlets.
