ANSWERS IN CAPS

With the newest technology, GAIA is working to create a detailed 3-D map of our region of the Milky Way. What are these precise measurements of the positions and movements of stars and other galactic bodies known as?
aerial spacing
aerodynamics
arithmetic
ASTROMETRY

What process allows galactic bodies to interact with each other by colliding and exchanging particles and matter?
confidence intervals
COSMIC SPALLATION
global clustering
pulsing

Before astronomers determined that PSR B1620-26 b was a planet, they went back and forth over its identity and thought that it could possibly be an object between the size of a planet and a small star. What did astronomers initially think that PSR B1620-26 b was?
A BROWN DWARF
a global cluster
a moon
a star burst

The stars that are being created today are mostly composed of hydrogen and helium.
True
FALSE

What is a planet that has its main orbit around a pulsar star, like PSR B1620-26 b, known as?
exoplanet
global cluster
brown dwarf
PULSAR PLANET

There are very, very few times that scientists make estimations because they don’t have enough time or data to test all the possible answers to the question they have.
True
FALSE

When the Milky Way was in its earliest ages, hydrogen, helium and other common elements were the only ones around.
TRUE
False

Older stars that are more original to the galaxy, reddish in color, and much cooler than their newer counterparts are classified as what kind of stars?
POPULATION || STARS
red dwarf stars
population I stars
brown dwarf stars

The blue, hotter stars tend to have shorter lifetimes than the red, cooler stars.
TRUE
False

Scientists have found things that suggest the stars in the disc and halo of the Milky Way are different ages. What has this led scientists to suspect?
that stars and the creation of the Milky Way are completely dependent on each other
THAT THERE WERE POSSIBLY TWO DIFFERENT FORMATIONS IN THE BEGINNING, RATHER THAN JUST ONE
that the Milky Way is an inhospitable place for stars to exists
that the Milky Way is ultimately causing stars to burn out faster than they should
