Exoplanet Detection Techniques and Challenges

The video explores the search for Earth-like planets, known as Earth 2.0, and the challenges astronomers face in determining their habitability. It highlights the use of spectroscopy and direct imaging to study exoplanets, despite current technological limitations. The video introduces starshade technology as a potential solution to block starlight and improve imaging of distant planets. It also discusses the future development of starshades and their potential integration into upcoming space missions.

What is the main reason astronomers have not yet confirmed the existence of a habitable Earth-like planet?

• Planets are too far away to study

• No planets found in habitable zones

• Insufficient data on exoplanets

• Lack of advanced telescopes

What technique allows astronomers to determine the chemical makeup of an exoplanet's atmosphere?

• Gravitational Microlensing

• Photometry

• Spectroscopy

• Astrometry

Why is direct imaging considered a promising method for finding extraterrestrial biosignatures?

• It can detect planets in other galaxies

• It is the most cost-effective method

• It allows for the study of planets without interference from their stars

• It can capture high-resolution images of stars

What is a starshade primarily designed to do?

• Enhance the brightness of distant stars

• Block the light from a star to observe its planets

• Capture images of galaxies

• Measure the temperature of exoplanets

What is a major challenge in deploying a starshade in space?

• Ensuring it unfolds correctly in space

• Finding a suitable launch vehicle

• Maintaining its temperature

• Protecting it from cosmic rays

Why do starshades have a petal-like design?

• To make them easier to launch

• To increase their size

• To reduce diffraction of light

• To improve aesthetic appeal

What is the current technological readiness level of starshades according to NASA?

• TRL 2

• TRL 8

• TRL 4

• TRL 6

Which upcoming space telescope is described as 'starshade compatible'?

• Chandra X-ray Observatory

• Hubble Space Telescope

• James Webb Space Telescope

• Roman Space Telescope

Who are the scientists recognized for their work on exoplanets and starshades?

• Dr. Carl Sagan and Dr. Edwin Hubble

• Dr. Sara Seager and Dr. David Charbonneau

• Dr. Stephen Hawking and Dr. Kip Thorne

• Dr. Neil deGrasse Tyson and Dr. Brian Cox

What is the primary goal of the Kavli Prize in astrophysics?

• To support young astronomers

• To fund space missions

• To develop new telescopes

• To honor breakthroughs in understanding the universe
