1. What is a nebula?
Answer: A nebula is a large cloud of gas and dust in space, often the birthplace of new stars and planetary systems.
2. What is a neutron star?
Answer: A neutron star is the collapsed core of a massive star that has exploded in a supernova. It is incredibly dense, with a mass similar to the Sun but a radius of only about 10 kilometers.
3. What is a quasar?
Answer: A quasar is an extremely energetic and distant active galactic nucleus, powered by a supermassive black hole at the center of the galaxy.
4. What are exoplanets?
Answer: Exoplanets are planets that orbit stars outside our solar system.
5. How do we find exoplanets?
Answer: Exoplanets are detected using methods like the transit method (observing the dimming of a star as a planet passes in front of it) and the radial velocity method (measuring the star’s wobble due to gravitational pull from a planet).
