Background
The man who first saw bright galaxy centers in 1918
Who was Heber Curtis? (In 1918, Heber Curtis used an optical telescope to see the bright core of NGC 1068)
The replacement for the Hubble Space Telescope
What is the James Webb Space Telescope?
Meaning of AGN
What is an Active Galactic Nucleus?
The rough amount of identified quasars
What is 1 million?
The year in which "zombie galaxies" were discovered
What is 2025? (A zombie galaxy is a galaxy that has stopped forming new stars but continue to exist)
The tool Carl Seyfert used to find/see the first active galaxy
What is a 100-inch hooker telescope? (Seyfert used this powerful telescope in the early 1940s to study the central regions of certain spiral galaxies, noting their unusually bright nuclei)
The year active galaxies were discovered
What is 1943?
What is an accretion disk?
The type of active galaxy that is the most luminous
What is a quasar?
This constellation is where the quasar 3C 279 is located
What is Virgo?
The time when radio galaxies were properly identified
What were the early 1950s? (In 1954, Martin Ryle and others used radio telescopes to detect powerful radio galaxies like Cygnus A)
The man who discovered active galaxies (early observation)
Who was Edward Fath?
The determining factor of an active galaxy
What is a supermassive black hole?
The amount of total galaxies that are active
What is 10%?
The rough amount of galaxies found by the Fermi Gamma-Ray Space Telescope in its first 7 years of operation
What is 1,000?
The man who discovered Quasars
Who is Maartin Schmidt? (In 1963, Martin Schmidt found quasars using the Hale telescope, showing they’re powered by black holes.)
The name of the first quasar discovered
What is 3C 273?
A quasar with it's accretion jets pointed towards earth
What is a blazar?
The distance of the farthest known active galaxy
What is 13 billion light years?
These two universities discovered the "infinity galaxy"
What are Yale University and the University of Copenhagen? (The infinity galaxy is a recently discovered galaxy nicknamed for its resemblance to an infinity symbol, formed by the collision of two spiral galaxies)
The technology in which black holes were confirmed in galaxies
What is the Hubble Space Telescope?
The men who proposed the concept of a supermassive black hole accreting gas as the power source for quasars
Who were Edwin Salpeter and Yakov Zeldovich (in 1964)?
A technique for measuring brightness of objects in the sky
What is Photometry?
The opposite of an active galaxy, a galaxy which has remained virtually unchanged for billions of years
What is a galactic fossil?
This is approximately 13 million light years and 650000 light years wide
What is the length of the Cosmic Vine?
