Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the observational confirmation?Afterglow detection and redshift measurements confirmed extragalactic origins and immense distances
2. What is the stellar nucleosynthesis?Key sites for the production of heavy elements via the r-process
3. What are gamma‑ray bursts?Gamma‑ray bursts are the brightest explosions in the universe. In just a few seconds they can release more energy than the Sun will produce in its entire 10‑billion‑year life.
4. Why do gamma‑ray bursts have short and long types?Short gamma‑ray bursts last less than two seconds, while long bursts last longer than two seconds. The two types come from different kinds of cosmic events.

Relativistic Jets: Highly energetic, collimated outflows of particles traveling at speeds close to the speed of light.
Core-Collapse Supernova: The explosive death of a massive star when its core can no longer support itself against gravity.
r-process Nucleosynthesis: A rapid neutron capture process responsible for creating the heaviest elements in the universe.
