SURPRISE BOB!!! This fictional cephalopod lives in a house modeled after a moai.
Who is Squidward Tentacles?
100
A product of nuclear fusion, these tiny particles make their way out of the core of the Sun and into space in just a few seconds.
What are neutrinos?
100
Mass is lost and energy is released during this process that combines lighter elements into heavier ones.
What is nuclear fusion?
100
Composed mostly of hydrogen, this is the name given to objects that are massive enough to sustain nuclear fusion at their cores.
What is a star?
200
These negatively charged particles surround the nucleus of an atom and are responsible for its chemical properties.
What are electrons?
200
A hole in the ground, a giant vat of dry cleaning fluid, and a puzzling result. This is the name of the famous neutrino experiment.
What is the Homestake gold mine experiment?
200
Positrons and neutrinos are released during this step of the proton-proton chain.
What is the first step?
200
O-type stars (very hot) feature this chemical signature in their spectra.
What is the presence of highly ionized gases?
300
This is the name given to an atom containing 2 protons and 1 neutron.
What is Helium-3?
300
The discrepancy between the expected and measured flux of tiny particles produced by the Sun and name given to the question: "Where are the missing 2/3 of solar neutrinos?"
What is the solar neutrino problem?
300
This energetic particle of light is released during the second step of the proton-proton chain.
What is a gamma ray?
300
This is the distance (in light years) to a star with a parallax angle of 0.4 arcseconds.
What are 8 lightyears?
400
These two elementary particles are found in the nuclei of atoms.
What are protons and neutrons?
400
The electron neutrinos produced inside of the Sun do this on their way to the Earth.
What is change flavors?
400
This is the amount of energy released when converting 1/3 of a kilogram of mass into energy.
What is 3x1016 J?
400
This is the correct order of the spectral classes from hottest to coolest.
What is OBAFGKM?
500
The most abundant element in the Sun.
What is hydrogen?
500
Tau, muon, and electron.
What are neutrino flavors?
500
Our most precious main sequence star uses this process to fuse protons into helium, releasing lots of energy.
What is the proton-proton chain?
500
The Sun's power output.
What is 4x1026 W?
