Final answer:
X-ray satellites mounted on satellites have provided evidence on dark matter distribution, black hole activity, and planetary atmospheres in the universe.
Step-by-step explanation:
X-ray satellites mounted on satellites have provided evidence on various aspects of the universe, including:
- Dark matter distribution: X-ray observations have helped researchers study the effects of dark matter on galaxy formation and large-scale structure of the universe.
- Black hole activity: X-ray telescopes have detected and studied X-ray emissions from black holes, providing valuable insights into their behavior and properties.
- Planetary atmospheres: X-rays can reveal information about the composition and dynamics of planetary atmospheres, such as the presence of X-ray auroras on Jupiter.
