- 2. A time when the first starts lights up a few hundred million years after the Big Bang, casting an end to the Dark ages.
- 3. What is the bright band of hydrogen gas in a fisheye lens picture of the night sky?

- 1. A control building made up of metal skins that protects the computers from telescope radiations.
- 4. a theoretical repulsive force that counteracts gravity and causes the universe to expand at an accelerating rate.
- 5. What are the disturbances in the curvature (fabric) of spacetime called?
- 8. An important factor in the shaping of our galaxy, where magnetism is ubiquitous in the universe.
- 9. What is the element that makes up most of the universe and is the fuel for stars?
- 11. A branch of astronomy that involves the origin and the evolution of universe
- 13. A transient astronomical event when a massive star or a white dwarf explodes, causing a sudden appearance of a "new" bright star.
- 14. A hypothetical matter that is thought to account for most matters in the universe.
- 15. A type of array formed when a large number of small, fixed antenna elements coupled to appropriate receiver systems.
