Juna Kollmeier: The most detailed map of galaxies, black holes and stars ever made

The video explores humanity's fascination with the dark and the universe, tracing the history of sky mapping from ancient times to modern efforts like the Sloan Digital Sky Survey (SDSS). It highlights the challenges and technological advancements in understanding the universe, including the study of stars, galaxies, and black holes. The role of citizen scientists and the potential future of mapping the universe are also discussed.

What initially sparked the speaker's curiosity about the universe?

• A love for astronomy books

• A fascination with ancient relics

• A childhood fear of the dark

• A school science project

What was the significant contribution of Tycho Brahe and Johannes Kepler to astronomy?

• They discovered the Big Dipper

• They mapped the entire universe

• They figured out how planets move around the Sun

• They invented the telescope

What is the primary goal of the Sloan Digital Sky Survey (SDSS)?

• To map the ocean floor

• To explore the depths of the Earth

• To study the weather patterns on Earth

• To map the sky and understand the universe

How does the SDSS5 improve upon previous surveys?

• By using larger telescopes

• By focusing only on the Milky Way

• By reducing the number of telescopes

• By making the focal plane entirely robotic

What makes black holes particularly perplexing?

• They emit only visible light

• They are just mass incarnate with no surface

• They have a visible surface

• They are made of water

What role do citizen scientists play in the SDSS?

• They write scientific papers

• They fund the research

• They analyze public data and make discoveries

• They build the telescopes

What was Hanny van Archelle's contribution to astronomy?

• She invented a new telescope

• She discovered a new planet

• She found a rare type of object in SDSS data

• She mapped the entire Milky Way

What is the ultimate goal of mapping the universe according to the speaker?

• To predict future cosmic events

• To find new planets for colonization

• To understand the universe and our place in it

• To create a star map for navigation

What does the speaker suggest is necessary to win the battle to understand the universe?

• Government funding and support

• A focus on only one aspect of the universe

• A large team of curious and creative people

• Advanced technology and individual effort

What is the speaker's final message to the audience?

• To focus on personal achievements
