Elliptical
Irregular
What galaxy is this?
Large Magellanic Cloud
Andromeda Galaxy
Hoag's Object
Small Magellanic Cloud
What is a quark star?
A hypothetical type of compact exotic star, where extremely high temperature and pressure has forced nuclear particles to form a continuous state of matter that consists primarily of free quarks.
A star emitting two high powered jets from each of the poles, due to it's magnetic field. It is otherwise known as a pulsar.
A black hole that has similar properties to a pulsar, and depending on how we see it from Earth, it is a quasar or blazar.
What is Planet Nine?
A planet that is primarily composed of free quarks.
A proposed planet in the outer region of the Solar System. It is thought to be the cause of gravitational anomalies within our Solar System.
Every single object affected by our Sun's gravitational effects.
What galaxy is this?
Small Magellanic Cloud
Large Magellanic Cloud
IC 1101
What is a black hole?
A region of spacetime exhibiting such strong gravitational effects that nothing, not even light, can escape from inside it.
A black dwarf that has gravitational effects so unusually powerful.
A star with very powerful gravitational properties that is completely engulfed by cosmic dust to appear black.
A near indestructible sphere in space that is made up of an element unknown to humans, that also is darkest element in the universe.
How do you create a black hole?
Any object compressed down into a space small enough
Causing a nuclear fission reaction powerful enough to generate gravity
Preventing as little light as possible to hit an object for long enough period of time
Painting a sphere black
Which image is a Spiral galaxy?
What is a quasi-star?
A hypothetical type of extremely massive star that may have existed very early in the history of the Universe. Unlike modern stars, which are powered by nuclear fusion in their cores, a quasi-star's energy would come from material falling into a central black hole.
A star so large and unstable that it can go supernova at any given moment
A type of star that emits a beam of radiation at each of its poles, otherwise known as a Pulsar
A dead star that is experiencing extreme pressure and heat, that it rips atoms apart and is in a state of matter that primarily consists of free protons, neutrons, and electrons
What is the closest galaxy to Earth?
Canis Major Dwarf (CMa Dwarf)
Draco Dwarf Galaxy
Andromeda
Cartwheel
If the Crab Nebula is a supernova remnant, and the center of it is a pulsar, what can you conclude?
A neutron star exists in the center
Quasar or blazar
Black Hole
Wormhole
