How Vast is Space? Insights from a NASA Expert

Fast Summary

• Space’s scale is vast, adn traveling to Pluto at highway speeds would take approximately 6,000 years.
• astronomers use “light-years” as a unit for measuring distances beyond the solar system; one light-year equals about 6 trillion miles.
• The closest star to the Sun is located four light-years away, while our Milky Way galaxy spans roughly 100,000 light-years across.
• NASA’s James Webb Space telescope has captured images of galaxies emitting light from around 13.5 billion years ago.
• Due to the universe’s expansion, distant galaxies are much farther away than their emitted age suggests.
• The observable universe is estimated to be about 92 billion light-years across, but its actual size remains unknown due to limitations in observation and measurement methods.
• Scientists remain uncertain whether the universe is finite or infinite.
