Dark matter and dark energy, two enigmatic components that dominate the universe, continue to intrigue scientists
and researchers at NASA and beyond. These invisible forces shape the cosmos in ways we are only beginning to
understand.
The Puzzle of Dark Matter
Dark matter, a mysterious substance that does not emit, absorb, or reflect light, comprises roughly 27% of the
universe. Despite its pervasive presence, dark matter’s exact nature remains elusive, sparking a quest for answers
within the scientific community.
NASA’s Contribution
NASA’s astrophysicists employ cutting-edge technologies such as the Hubble Space Telescope and the James Webb Space
Telescope to study the effects of dark matter on the universe. By observing gravitational lensing and galactic
rotation curves, researchers aim to unravel the secrets of this invisible matter.
Unveiling Dark Energy’s Influence
Dark energy, an even more mysterious force, accounts for approximately 68% of the universe’s energy content. It is
believed to be responsible for the accelerated expansion of the universe, a phenomenon that defies conventional
understanding.
NASA’s Endeavors
NASA’s investigations into dark energy involve large-scale surveys like the Wide Field Infrared Survey Telescope
(WFIRST) and the Euclid mission. These endeavors seek to map the distribution of galaxies and explore the cosmic
microwave background to shed light on the nature of dark energy.
