See remarkable NASA photos of a new volcano eruption

ISS astronauts and NASA satellites capture amazing photos of the Raikoke volcano eruption.

  • Astronauts and satellites take memorable photos of the Raikoke volcano eruption in the Kuril Islands.
  • The eruption is the first in volcano since 1924.
  • The plume of the eruption got as high as 17 km (10 mi).


As far as out-of-this-world pictures go, NASA got an amazing opportunity to snap photos of an erupting volcano from the International Space Station. On June 22nd, 2019, the Raikoke Volcano on Russia's Kuril Islands, which last exploded in 1924, suddenly let out a giant plume of ash and gas from its 700-meter crater.

Astronauts were able to take pics of the narrow column of the plume as it rose and expanded over an area called the umbrella region. That's where the plume stops rising, its density equalizing with that of the surrounding air.

As Simon Carn, a volcanologist at Michigan Tech, explained about the picture below - "The ring of white puffy clouds at the base of the column might be a sign of ambient air being drawn into the column and the condensation of water vapor. Or it could be a rising plume from interaction between magma and seawater because Raikoke is a small island and flows likely entered the water."

Volcanic Ash Advisory Centers in Tokyo and Anchorage reported that the ash had reached as high as 13 kilometers (8 miles). Data from the CALIPSO satellite shows that some segments of the plume reached the altitude of 17 kilometers (10 miles).

Scientists see 'rarest event ever recorded' in search for dark matter

The team caught a glimpse of a process that takes 18,000,000,000,000,000,000,000 years.

Surprising Science
  • In Italy, a team of scientists is using a highly sophisticated detector to hunt for dark matter.
  • The team observed an ultra-rare particle interaction that reveals the half-life of a xenon-124 atom to be 18 sextillion years.
  • The half-life of a process is how long it takes for half of the radioactive nuclei present in a sample to decay.

  • A new study proposes that language could change dramatically on long space voyages.
  • Spacefaring people might lose the ability to understand the people of Earth.
  • This scenario is of particular concern for potential "generation ships".
