Hint
Answer
Highly magnetized rotating neutron star that emits a beam of electromagnetic radiation.
Pulsar
Spiral galaxy approximately 2.5 million light-years from the Milky Way. In the future may form a giant galaxy with the Milky Way.
Andromeda
Geometric theory of gravitation published by Albert Einstein in 1916.
General Relativity
Jupiter's moon hypothesized to have a water ocean beneath its surface that could support life.
Europa
The most common element on Earth, forming much of its core.
Iron
Which conic section is the shape of a planetary orbit?
Ellipse
Type of stellar remnant that can exist for trillions of years and will be the fate of the Sun.
White dwarf
Satellite of Jupiter and the largest moon in the Solar System. May have layered oceans beneath its surface.
Ganymede
Type of matter hypothesized to account for 27% of the total mass–energy of the known universe.
Dark matter
Particle physics theory concerning the electromagnetic, weak, and strong interactions of the known subatomic particles.
Standard Model
Subatomic particle with no electric charge and with a mean lifetime of 15 minutes (when free).
Neutron
Hypothetical topological feature of spacetime that would fundamentally be a "shortcut" through spacetime.
Wormhole
Electrically neutral, weakly interacting elementary subatomic particle.
Neutrino
Ripples in the curvature of spacetime that propagate as a wave.
Gravitational waves
The force carrier for the electromagnetic interaction.
Photon
Boundary around a black hole beyond which events inside it cannot affect an outside observer.
Event Horizon
Which planet is about 2.3 light-minutes distance from earth?
Venus
Natural science conducted in order to understand how the universe behaves.
physics
Extremely luminous burst of radiation of a dying massive star.
Supernova
Mathematical term in the Einstein equations for general relativity that accounts for a expanding universe. It is the value of the energy density of the vacuum of space.
Cosmological constant
Hint
Answer
The most energetic and distant members of a class of objects called active galactic nuclei.
Quasar
Astronomer known for showing that the recessional velocity of a galaxy increases with its distance from the earth, implying the universe is expanding.
Edwin Hubble
Unit of energy, work, or amount of heat in the International System of Units, with symbol J.
Joule
Red supergiant of the constellation of Orion that is predicted to explode in a supernova in the near future.
Betelgeuse
Extremely high frequency electromagnetic radiation.
Gamma ray
Nuclear reaction in which two or more atomic nuclei collide at a very high energy and join to form a new type of atomic nucleus.
Nuclear Fusion
Subatomic particle with a positive electric charge and composed of 2 up quarks and 1 down quark.
Proton
Theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings.
String theory
Planet whose mass is 2.5 times that of all the other planets in the Solar System combined.
Jupiter
Elementary particle responsible for the mechanism that gives mass to some other fundamental particles.
Higgs boson
The third-most abundant element in the universe.
Oxygen
As of 2014 is the largest and most complex experimental facilitiy ever built.
Large Hadron Collider
Physical constant that is the quantum of action in quantum mechanics.
Planck constant
What is the wavelength of the cosmic background radiation?
Microwave
Which planet as an orbital period of about 88 Earth days?
Mercury
Radiation that is predicted to be released by black holes, due to quantum effects near the event horizon.
Hawking radiation
A measure of a thermodynamic system's disorder, or a measure of progressing towards thermodynamic equilibrium.
Entropy
Elementary particles that combine to form composite particles called hadrons, the most stable of which are protons and neutrons.
Quarks
English physicist and mathematician who is widely recognised as the most influential scientist of all time and as a key figure in the scientific revolution.
Isaac Newton

could hadron collider be accepted ( and I typed beetelgeuse, not the exact spelling, but perhaps close enough to be accepted?) And I typed quasar as a guess for antoher question, but not the right one sigh. (same with proton). Still 27/30 pleased with that

"Lambda" should also be accepted in place of the Cosmological Constant. This is standard in modern cosmology textbooks.
