Questions & Answers

Q: How does a telescope work?

Telescopes work by using lenses or mirrors to focus light from distant objects onto a small spot, which can then be viewed or converted into electronic signals.

Q: Did the Cosmic Background Explorer satellite function similarly to the Hubble Space Telescope?

While the Cosmic Background Explorer satellite and the Hubble Space Telescope have different technologies, they both collect data from space. The Cosmic Background Explorer satellite focused on mapping the entire sky, while the Hubble Space Telescope captured detailed images of galaxies and nebulae.

Q: How were scientists able to measure cosmic background radiation?

Scientists used equipment that could measure the static from televisions tuned to channels with no broadcast. They also developed tiny thermometers to measure the temperature rise caused by the cosmic background radiation.

Q: How did Dr. John Mather's work on cosmic background radiation lead to the Nobel Prize?

Dr. Mather's research involved measuring the color of cosmic background radiation and matching it with the predicted spectrum of the expanding universe. His contributions were recognized with the Nobel Prize in 2006.

Summary & Key Takeaways

• Dr. John Mather shares his background growing up in a rural area with limited resources, but his passion for science was ignited through books and experimentation.

• He outlines his educational journey, from attending public high school to studying physics at Swarthmore College and completing his graduate studies at UC Berkeley.

• Dr. Mather explains how his failed thesis project paved the way for his career at NASA, leading to his contributions to the Cosmic Background Explorer satellite and the discovery of the cosmic microwave background radiation.
