How do we classify galaxies? - We classify galaxies based on if they are spiral, elipitical or irregular. The size is determined be the halo. What kind of stars do elliptical galaxies contain? - Ellipitcal galaxies have only older stars. There is no gas or dust to create new stars. What kind of stars do spiral galaxies contain? - Spiral Galaxies contain old and new stars and much gas and dust. How is the light from active galaxies different from light from normal galaxies? - Active ga...

EAPS 112 - Exam 1 Questions & Answers 2023/2024 The Big Bang Theory - ANSWER-All matter and energy began in an indefinitely small, hot, dense state - and has subsequently exploded into being with a bang nearly 14 billion years ago. Evidence for the Big Bang Theory - ANSWER-Galaxies moving away from us will become more red colored in our reference frame due to the Doppler effect. Origins of Elements - ANSWER-- Hydrogen and Helium - Big bang - Helium to Iron - Stellar Fusion (S-Process) ...

Hydrostatic Equilibrium The current distinguishing criterion between dwarf planets and small Solar System bodies Evolution of stars of different mass -Star formation produces a wide variety of stars -Only a few high-mass stars (O, B Type) are produced -The lowest mass stars (eg.M type) are the most common. -If a "star" forms with a mass less than about 1/10 the mass of the Sun, it will not have enough pressure in its core to ignite nuclear fusion. •The lower limit to the mass of a...

dark energy + evidence correct answers a mysterious repulsive force that appears to be causing the expansion of the universe to accelerate Type Ia supernovae as standard candles; Hbl law says they should be moving faster there; inverse square law for light dictates that dimmer = farther; calculated dstncs to things are even farther than their redshift predicts; they are being pushed away dark matter + evidence correct answers matter (gravity, attractive force) that does not give off electr...
