Early Universe + Black Holes
True or False. Black holes are like the universe's vacuum cleaners and suck up anything around them.
False.
Our galaxy is named this.
What is the Milky Way?
This type of star makes up 90% of all stars
What is a main sequence star?
An exoplanet is this.
What is a planetary body outside our solar system?
The primary purpose to send the James Webb telescope to space.
What occurred during the big bang and learning more from primordial galaxies?
The exact point where a black hole first forms.
What is a singularity?
The most common galaxy in the universe is this shape.
What is spiral?
No matter what its size, every star goes through this phase as it starts to die.
What is a red giant?
The purpose for finding exoplanets and investigating their landscapes.
What is to search for other forms of life, or learn more about the origin of the universe?
Primary telescope used prior to the James Webb.
What is the Hubble?
The barrier of a black hole that not even light can escape from.
What is the event horizon?
Found at the center of every Galaxy
What is a super massive black hole?
Stars are formed this way.
What is by gas and dust clouds having enough internal gravity to form into one object?
Name 3 of the 4 (or all 4 if you can) types of exoplanets.
What are terrestrial, gas giant, Neptune-like and Super-Earth?
An important finding from the data so far on the James Webb.
Variety of possibilities here. Example: Recent discovery of ice on the outskirts of star, which could potentially contain life.
The two theories on how the universe will continue to grow in the future.
What is the "big crunch" and infinite expansion? One theory is we keep expanding forever until we don't have energy left, and the other is we do that but get to an extreme and then rubber-band back to a singularity to explode all over again.
A galaxy evolution between a large and small galaxy that throws a ring of gas, dust and stars to the outer edge.
What is a merger?
This is produced when a medium star dies.
What is a white dwarf?
Decade the first exoplanet (officially) was discovered in.
Describe the launch and deployment process of the James Webb telescope. Should contain decent description around each step.
The launch required a housing unit for the mirrors and sun-shield to be folded into, while the external thrusts and further thrusters could be deposited in the atmosphere. Once it had reached the destination the object could slowly unfold on the two ends before the sun shield opened and finally the full 18 paneled mirror would engage over a 30 day period.
Explain the theory behind black hole formation and growth and why scientists are perplexed there are no ____ size black holes present.
What is the formation from supernovae that eventually collide or merge to form the supermassive black holes at the middle of galaxies? What is intermediate size?
An extremely luminous emission at the center of a galaxy that emits all forms of electromagnetic waves.
What are quasars?
The internal and external forces, and how they change during the life cycle of star, which cause it to die.
What are gravity and fusion? Fusion begins as the stronger force as the resources of the sun drain, until eventually they become equivalent forces, which causes a shift to the Red Giant phase. This phase remains until all the fuel is used and the star dies as gravity slowly overcomes.
Name and explain 3 of the 5 ways of discovering exoplanets discussed in the video.
What are direct imaging (covering a sun to find nearby planets), radial velocity (also: watching for wobble which is seeing how much the sun alters off its axis to discover nearby planets), transit (uses the light blocked by the sun to determine planetary size and pattern), gravitational microlensing (seeing the light slightly shift around a moving star due to some external gravitational pull nearby), and astrometry (similar to wobble but utilizing nearby stars to determine if the wobble is occurring).
Who invented the first telescope? Hint: This is a tougher question than it may seem
Who is Hans Lippershey? He was a Dutch lensmaker who had his patent submitted shortly before Galileo began his discoveries. The first one with a refractive lens inside was made by Newton.
