NASA probes 5 key mysteries of dark matter and dark energy in the expanding universe

NASA continues its efforts to unravel the mysteries of dark matter and dark energy that dominate the universe. Though they constitute most of the cosmos, little is understood about them.

Dark matter and dark energy make up approximately 95% of the universe, yet scientists continue to face challenges in understanding their true nature.

Here are five crucial questions NASA is working to answer about dark matter and dark energy.

NASA estimates dark matter accounts for around 27% of the universe. While its existence is confirmed, its exact composition remains unknown.

Dark matter does not emit light or energy, making it invisible. Researchers can only observe its influence on stars and galaxies.

Dark energy, a more enigmatic force, comprises about 68% of the universe. It appears to accelerate the expansion of the cosmos.

NASA's observations indicate that dark energy causes the universe to expand increasingly faster, a phenomenon that scientists are still working to explain.

Both dark matter and dark energy are believed to shape the formation and behavior of galaxies across the universe.

NASA uses space telescopes to map the potential locations of dark matter, studying how it bends the light from distant galaxies.

Scientists hypothesize that dark matter could be composed of unknown particles. Ongoing experiments aim to detect these particles.

NASA relies on advanced tools like the Hubble Space Telescope and upcoming missions to unlock the mysteries of dark matter and dark energy.
