Supernovae - Begin by reading the background information on supernovae. . Watch this teacher video, which illustrates how supernova light curve data can be fit to models in order to measure the distance modulus of supernovae. - Use the supernovallightcurve explorer to examine the data from supernova 1998aq. 1. What is the distance modulus of the supernova \( 1998 a q \) ? [Insert answer here] completing the Lab 1. Return to the course and complete the lab quiz to demonstrate your understanding. 2. Then subrrit this completed lab document by following the directions in our course.

Supernovae have been pivotal in expanding our understanding of the universe. The first recorded supernova, SN 1054, was so bright that it could be seen in daylight and later became the Crab Nebula, a testament to the spectacular aftermath of a stellar explosion. Fast-forward to the late 1990s, when observations of Type Ia supernovae led to the groundbreaking discovery of dark energy, dramatically reshaping our understanding of cosmic expansion! When diving into real-world applications, supernovae serve as cosmic lighthouses, helping astronomers measure vast distances in the universe. The consistent brightness of certain types of supernovae allows them to act as "standard candles." By analyzing the light curves, or brightness over time, scientists can determine not only distance but also the expanding rate of the universe, leading to profound insights into its history and fate!
