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).

Philosophers like to present their works as if everything before it was wrong. Sometimes, they even say they have ended the need for more philosophy. So, what happens when somebody realizes they were mistaken?
Sometimes philosophers are wrong and admitting that you could be wrong is a big part of being a real philosopher. While most philosophers make minor adjustments to their arguments to correct for mistakes, others make large shifts in their thinking. Here, we have four philosophers who went back on what they said earlier in often radical ways.
We must rethink the "chemical imbalance" theory of mental health.
