Answer 9

A highly magnetic neutron star

Question 10

Quasar

Answer 10

An extremely luminous and energetic active galactic nucleus powered by a supermassive black hole.

Question 11

Accretion Disk

Answer 11

A rotating disk of gas and dust falling into a central object like a star or black hole.

Question 12

Main sequence

Answer 12

The stable phase in a star’s life where it fuses hydrogen into helium.

Question 13

Helium flash

Answer 13

A sudden onset of helium fusion in the core of low-mass stars.

Question 14

Chandrasekhar Limit

Answer 14

The maximum mass (~1.4 solar masses) a white dwarf can have before collapsing into a neutron star or black hole.

Question 15

Parallax

Answer 15

The apparent shift in the position of a nearby star against the background of distant stars, used to measure distance.

Question 16

Hubble’s Law

Answer 16

The observation that galaxies are moving away from us at speeds proportional to their distance.

Question 17

Radio Telescope

Answer 17

A device that detects radio waves from space.

Question 18

Adaptive Optics

Answer 18

A technology that adjusts a telescope’s mirror to compensate for atmospheric distortion.

Question 19

Gravitational Lensing

Answer 19

The bending of light from a distant object, such as a galaxy or quasar, due to the gravitational influence of an intervening massive object, like a galaxy cluster.

Question 20

Blue shift

Answer 20

The opposite of red shift when it’s getting closer

Question 21

Solar Wind

Answer 21

A stream of charged particles released from the upper atmosphere of the Sun, influencing space weather.

Question 22

Lagrange Point

Answer 22

A position in space where gravitational forces and the centrifugal force balance out, allowing objects to remain in a stable position relative to two larger bodies.

Question 25

Tachyon

Answer 25

A hypothetical particle that always moves faster than light, used in theoretical models of faster-than-light communication.

Question 26

Cosmological Constant

Answer 26

A term introduced by Einstein in his equations of general relativity to represent a constant energy density filling space homogeneously.

Question 27

Cosmological Constant

Answer 27

Λ

Question 28

Quantum Foam

Answer 28

The fluctuating structure of spacetime at the Planck scale, hypothesized to be a "frothy" region at extremely small scales.

Question 29

Planck Time

Answer 29

Planck Time Definition: The time it takes for light to travel one Planck length, considered the smallest meaningful unit of time

Question 30

Graviton

Answer 30

The hypothetical quantum particle that mediates the force of gravity in quantum theories of gravity.

Question 32

Oort Cloud

Answer 32

A distant, spherical shell of icy objects surrounding the solar system, believed to be the source of long-period comets.
