Hubble Science: Dark Energy, A Mysterious Force

The Hubble Space Telescope is crucial in exploring the universe's mysteries, particularly dark energy, which is linked to the accelerating expansion of the universe. This discovery, made possible by Hubble and other telescopes, earned a Nobel Prize. Current research focuses on refining the universe's expansion rate and addressing discrepancies between expected and actual measurements.

What is one of the mysteries that the Hubble Space Telescope is helping to investigate?

• The origin of cosmic rays

• The phenomenon of dark energy

• The existence of parallel universes

• The formation of black holes

What did the discovery of the universe's accelerating expansion lead to?

• The identification of new galaxies

• The end of the Big Bang theory

• A Nobel Prize-winning discovery

• A new theory of relativity

What is one possible explanation for the universe's accelerating expansion?

• The presence of black holes

• The influence of nearby galaxies

• A new type of star

• A repulsive force or new physics
