See remarkable NASA photos of a new volcano eruption

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

See remarkable NASA photos of a new volcano eruption

Raikoke Volcano eruption. June 22, 2019.

  • 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).

Astronaut photograph ISS059-E-119250 was taken by the Expedition 59 crew on June 22, 2019.

Google’s Sycamore beats top supercomputer to achieve ‘quantum supremacy’

The achievement is an important milestone in quantum computing, Google's scientists said.

Google
Technology & Innovation
  • Sycamore is a quantum computer that Google has spent years developing.
  • Like traditional computers, quantum computers produce binary code, but they do so while utilizing unique phenomena of quantum mechanics.
  • It will likely be years before quantum computing has applications in everyday technology, but the recent achievement is an important proof of concept.

Face mask study reveals worst material for blocking COVID-19

A study published Friday tested how well 14 commonly available face masks blocked the emission of respiratory droplets as people were speaking.

Fischer et al.
Coronavirus
  • The study tested the efficacy of popular types of face masks, including N95 respirators, bandanas, cotton-polypropylene masks, gaiters, and others.
  • The results showed that N95 respirators were most effective, while wearing a neck fleece (aka gaiter) actually produced more respiratory droplets than wearing no mask at all.
  • Certain types of homemade masks seem to be effective at blocking the spread of COVID-19.
