Key Takeaways:
- 1. The Hubble Space Telescope captured an image of the galaxy cluster Abell 209 located 2.8 billion light-years away.
- 2. Abell 209 contains over a hundred galaxies separated by hot, diffuse gas and dark matter.
- 3. Hubble observations of Abell 209 help astronomers study dark matter and dark energy, using gravitational lensing to map mass distribution.
The NASA/ESA Hubble Space Telescope captured an image of the galaxy cluster Abell 209, revealing over a hundred galaxies separated by hot gas and dark matter. Dark matter, which comprises 25% of the universe, is invisible but detected through its gravitational influence. Hubble observations aid in studying dark matter and energy, with gravitational lensing helping map the mass distribution within the cluster.
Insight: Hubble's observations of galaxy clusters like Abell 209 provide valuable insights into dark matter and energy, aiding in understanding the universe's evolution.
