NASA | Van Allen Probes Reveal Previously Undetected Radiation Belt Around Earth

The video discusses the discovery of radiation belts around Earth in 1958, marking the start of the space age. In 2012, NASA's Van Allen probes provided detailed images of these belts, revealing a third, temporary radiation belt. Scientists are exploring how these belts react to solar energy, with new findings offering insights into space phenomena.

What was the first major discovery of the space age in 1958?

• The Van Allen radiation belts

• The first human in space

• The first satellite launch

• The discovery of water on Mars

What significant event occurred in August 2012 related to the Van Allen belts?

• The discovery of a third radiation belt

• The first manned mission to Mars

• The launch of the first space station

• The detection of gravitational waves

How long did the newly discovered third radiation belt last?

• Indefinitely

• A year

• A week

• A month

What do scientists already know about the behavior of the radiation belts?

• They are only present during solar flares

• They remain constant over time

• They shrink and swell in response to solar energy

• They are unaffected by solar activity

What does the discovery of a new radiation belt suggest about space exploration?

• All mysteries of space have been solved

• There are still surprises and mysteries to uncover

• Space exploration is no longer necessary

• The radiation belts are not important
