Transcript

So my name is Nora Luetzgendorf. I'm an instrument scientist for the James Webb Space Telescope, so I work for one of the four instruments of the James Webb Space Telescope. That instrument is called NIRSpec, and it's short for Near Infrared Spectrograph. So a spectrograph basically is similar to a prism. What you probably also have at home, you ca... Read More

Questions & Answers

Q: What is the role of NIRSpec on the James Webb Space Telescope?

NIRSpec is an instrument that acts like a prism, splitting light into rainbow colors to analyze the spectrum of celestial objects and gather information about their composition.

Q: How far away is the galaxy that was observed by the telescope?

The galaxy observed by the telescope was approximately 13.1 billion light-years away, suggesting that it existed during the early stages of the universe.

Q: How does the spectrum of an object provide information about the universe?

The spectrum can reveal the presence of different elements in the object, helping scientists understand the composition and characteristics of celestial bodies.

Q: What inspired Nora Luetzgendorf to become an astronomer?

Nora's grandfather, who had an interest in astronomy, sparked her fascination with cosmic objects, particularly black holes. Conversations with him during her childhood influenced her decision to study physics and specialize in astronomy.
