Answers to Daily Trivia Quiz # 106 - Outer
Space
In a study published in the journal Science, a team of
researchers says the universe is between 11.2 billion and 20 billion
years old.
A black hole is a region of spacetime from which nothing can
escape, even light.
As of now the closest known one is thought to lie at about 1,600
light years from Earth.
A supernova is a stellar explosion which produces an extremely
bright object made of plasma that declines to invisibility over
weeks or months.
The scientific consensus is that quasars are powered by material
falling into super massive black holes in the nuclei of distant
galaxies.
Neutron stars are the collapsed cores of some massive stars.
Brown dwarfs are sub-stellar objects with a mass below that
necessary to maintain hydrogen-burning nuclear fusion reactions in
their cores.
They are stars of 0.4 - 10 times the mass of the Sun which have
exhausted their supply of hydrogen in their cores and switched to
fusing hydrogen in a shell outside the core.
The core of the Sun is 27,000,000 degrees Fahrenheit. The
surface of the Sun, is only 10,000 degrees Fahrenheit.
A solar flare is an explosion on the Sun that happens when
energy stored in twisted magnetic fields is suddenly released.
Cosmic rays are high energy charged particles, originating in
outer space, that travel at nearly the speed of light and strike the
Earth from all directions.
The Van Allen Radiation Belt is a torus of energetic charged
particles (plasma) around Earth, trapped by Earth's magnetic field.
Hydrogen
Jupiter is about 90% hydrogen and 10% helium (by numbers of
atoms, 75/25% by mass) with traces of methane, water, ammonia and
"rock"
Jupiter has 63 known satellites (as of Feb 2004): the four large
Galilean moons plus many more small ones some of which have not yet
been named.
Mercury rotates three times in two of its years.
The Big Dipper is a group of seven bright stars, 3 which form a
handle and 4 which form a bowl.
The little dipper has 6 stars.
A constellation is a group of stars that, when seen from Earth,
form a pattern.
There are 88 constellations.
A: The Great Red Spot on Jupiter is a hurricane-like storm
system. It is large enough that two Earths could fit across it.
Gold only comes from Super Novae.
The parsec is a unit of length used in astronomy, approximately
equal to 3.261 light years.
