4, and satellites in orbit have been watching closely.

What is it? The volcano Anak Krakatau started spitting out ash and lava on Sept.

4.

On an archipelago between Sumatra and Java, the island volcano's sudden eruption grounded flights , closed schools and even stopped fishing in the area.

The volcano launched ash into the air and into the city of Jakarta and the Lampung province during a 25-hour-long eruption.

But even following this eruption, Anak Krakatau remained active throughout the weekend.

In fact, the volcano is still so active that it could erupt again soon.

But it wasn't just people on Earth watching the volcano erupt this past weekend.

The Landsat 8 satellite, operated by NASA and the U.S.

Geological Survey (USGS), spotted a white plume of volcanic gas billowing into the atmosphere all the way from space.
