black holes
milky way
miscellaneous
100
speed of light
What is 3x10^5 km/sec
100
the supernova that requires a binary system and is powered by thermonuclear energy
What is Type Ia supernova?
100
The theory that explains this phenomenon: Sun is a massive object so it will curve the space around it. If i observe a star very close to the sun, it’s position on the sky will be shifted due to the curvature of the space around the sun.
What is Einstein's theory of relativity?
100
number of stars in milky way
What is 300 billion stars
100
what Einstein called his "biggest blunder"
What is cosmological constant?
200
the distance of AU in km
What is 1.5x10^8 km
200
type of star that is about the size of a city
What is neutron star?
200
the sphere around a black hole from within which nothing can escape; the place at which the exit cones close
What is event horizon?
200
how many lightyears across the Milky Way is
What is 100,000 lightyears
200
what is causing university expansion to accelerate
What is dark energy
300
how far away alpha centauri is (in lightyears)
What is 4.3 lightyears
300
the core consists mostly of iron minutes before the star's core explodes into this type of supernova
What is type II supernova
300
how we find blackholes
What is finding and observing xray emitting objects?
300
the most abundant element in interstellar gas
What is hydrogen
300
Months before a star explodes as a type Ia supernova, its core consists mostly of this element
What is carbon
400
elusive, very fast, very low mass particles produced in nuclear reactions
What are neutrinos?
400
this is found at the center of crab nebula
What is pulsar?
400
when star is entirely within it's event horizon, and no light can escape, this is the radius of the star
What is the Schwarzschild radius?
400
type of stars found in disc of milky way
What is population I stars?
400
the reason why the sun will never be a nova
What is not having a binary companion star
500
the axes of a blackbody radiator diagram
What has x axis (wavelength), and y axis (brightness)
500
the supernova with a higher luminosity
What is Type Ia supernova?
500
What a collapsing star reaches when it contracts to zero radius
What is a singularity
500
where all emission and reflection nebulae are found in the milky way
What is the disc
500
the stars that exhibit period luminosity
What are RR lyrae stars
