Galaxies
Which type of Galaxy are we a part of? Why do they call it that type?
Spiral- it moves in a spiral-like formation
What is the first step of a star after being a nebula?
A protostar
describe our Sun in terms of its size, formation, and color
It's a yellow, mid-sized main sequence star.
Which type of galaxy is the youngest and brightest in the universe?
The Quasar Galaxy
Do smaller or larger stars live longer? Why?
Smaller- they don't need to use as much energy.
How do you determine a star's brightness from Earth?
Its absolute brightness and distance from Earth.
Which galaxy is most likely to form a new star? Which galaxy is least likely? Why?
Least: Elliptical
Amount of gas will drive this
Supernova or planetary nebula- it puts out so much space junk that a star can form with just some gravity.
List the following in order of brightness from low to high: Yellow star, red star, blue star.
red, yellow, blue
Which galaxy is most likely to form a neutron star or black hole other than a Quasar?
Irregular- lots of gas
Which step in star formation causes the best and most gasseous types of nebulas? Why?
Supergiant supernova- it implodes a massive star, putting a bunch of space junk out there.
Describe what our solar system might look like if someone were to visit it in about 30 billion years.
Relating it to the galaxy, why did the dinosaurs see different stars than us 300 million years ago?
The spiral galaxy is spinning giving us a different view of the universe.
Name 3 similarities between a black hole and a neutron star.
1. A ton of mass
2. Came from a supergiant
3. Extremely difficult to see from Earth.
Using your knowledge of star formation, take a guess at how a Quasar galaxy forms and why it's the youngest galaxy.
It possibly formed from an extremely powerful supernova that was once a supergiant and eventually a nebula, forming one extremely large black hole attracting other things to it forming a Quasar
