3. What is the bright band of hydrogen gas in a fisheye lens picture of the night sky?
6. A region of the electromagnetic radiation spectrum where wavelengths range from 700nm to 1mm.
8. What is the element that makes up most of the universe and is the fuel for stars?
9. the location where 200-250 large dishes will be built.
11. What are the disturbances in the curvature (fabric) of spacetime called?
14. A time when the first starts lights up a few hundred million years after the Big Bang, casting an end to the Dark ages.
15. An important factor in the shaping of our galaxy, where magnetism is ubiquitous in the universe.
16. A hypothetical matter that is thought to account for most matters in the universe.
19. A control building made up of metal skins that protects the computers from telescope radiations.
20. a theoretical repulsive force that counteracts gravity and causes the universe to expand at an accelerating rate.

1. The world's largest radio telescope
2. A type of array formed when a large number of small, fixed antenna elements coupled to appropriate receiver systems.
4. The physicist describes gravity as a geometric property of space and time.
5. A transient astronomical event when a massive star or a white dwarf explodes, causing a sudden appearance of a "new" bright star.
7. a high-speed data transmission medium. Digital data is transmitted through the cable through rapid pulses of light.
10. An astronomical instrument that consists of a radio receiver and an antenna system that is used to detect radio-frequency radiation emitted by extraterrestrial sources.
12. A rapidly spinning neutron star that is highly magnetized.
13. What is the name of the agency that designed and engineered Australian Square Kilometer Array Pathfinder (ASKAP)?
17. an object that turn radio waves into electricity, then transformed into light
18. A branch of astronomy that involves the origin and the evolution of universe
