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 supernova type?Type Ia
2. What is the progenitor system models?Single-degenerate and double-degenerate scenarios
3. Why do Type Ia supernovae help scientists measure how far away galaxies are?Type Ia supernovae shine with almost the same peak brightness. By comparing how bright they look to us, astronomers can calculate their distance using the inverse square law of light.
4. How does a star become a Type Ia supernova like SN 1998aq?A white dwarf in a binary system pulls matter from its companion star. When it reaches about 1.4 times the Sun's mass, it can no longer hold itself together and explodes in a thermonuclear explosion.

Chandrasekhar Limit: The maximum mass a white dwarf star can sustain before undergoing gravitational collapse, approximately 1.4 solar masses.
Light Curve: A graph showing the change in brightness of an astronomical object over time.
Dark Energy: A hypothetical form of energy believed to be responsible for the accelerating expansion of the universe.
