Questions & Answers

Q: How does the James Webb Space Telescope differ from the Hubble Telescope in terms of power and capabilities?

The James Webb Space Telescope is 100 times more powerful than the Hubble Telescope and can see back in time to the birth of the universe. Its larger mirrors allow it to capture the earliest starlight, and its focus on measuring heat infrared light enables it to observe the universe's first galaxies.

Q: What role does dark matter play in the formation and evolution of galaxies?

Dark matter acts as the scaffolding of the universe, providing the structure on which galaxies form and evolve. Without dark matter, galaxies, including our own, would not exist. The Webb telescope aims to observe galaxy evolution in detail and potentially reveal more about dark matter.

Q: What potential discoveries could the James Webb Space Telescope make regarding the possibility of extraterrestrial life?

By studying the chemistry of exoplanets, the Webb telescope could provide insights into habitable environments and the presence of key compounds like carbon dioxide and methane. This information could help scientists determine if a planet is truly habitable and potentially support life.

Q: What are the challenges and risks associated with launching and operating the Webb telescope?

The major challenge is unfolding the entire telescope aboard the rocket and ensuring that all systems, including the innovative sunshield, function perfectly. The mission's success is crucial to NASA's reputation, given the high investment and the potential for groundbreaking scientific discoveries.

Summary & Key Takeaways

• NASA is set to launch the James Webb Space Telescope, the largest and most expensive instrument ever flown, which is 100 times more powerful than the Hubble Telescope.

• The telescope has 18 hexagonal mirrors that fold out to form one mirror, allowing it to capture the earliest starlight in creation and see back in time to the Big Bang.

• Webb is designed to measure heat infrared light to see the universe's first galaxies, understand dark matter, and possibly discover conditions for extraterrestrial life.
