True False questions for Astronomy

Question	Answer
Stars do not twinkle; the instability of the atmosphere causes this effect.	True
The Compton GRO was the first telescope used for our exploration of high-energy astronomy.	False
Photography with film is still the preferred way of capturing fine detail in the faintest, most distant galaxies.	False
All the planets' orbits are even spaced.	False
Most astronomers now believe the demise of the dinosaurs 65 million years ago was caused by a large asteroid impacting the Yucatan peninsula area.	True
Many astronomers now regard Pluto as just the largest of thousands of Kuiper Belt bodies found beyond Neptune	True
The Oort Cloud lies closer to the Sun than the Kuiper Belt.	False
As a rotating gas cloud contracts, it spins faster.	True
In the solar nebular theory, the dusty disk condensing around the Sun's equator became the ecliptic plane in which the planets then formed.	True
Due to their great masses, all four Jovian worlds are much denser than earth.	False
A Kuiper Belt object was recently discovered that may be larger than Pluto	True
Astronomers have not yet been able to detect planets outside our solar system	False
We would expect other planets beyond our own solar system to orbit the equators of their home stars, as our own planets orbit the sun.	True
Compared to Earth, the Moon lacks a hydrosphere, atmosphere, and a magnetosphere	True
The moon keeps one side facing the Earth because it doesn't rotate on its axis.	False
Greenhouse gases in our atmosphere trap just enough heat to keep the earth's oceans liquid	True
The Earth's inner core is about the same temperature as the surface of the Sun.	True
A seismograph could register P but not S waves from an epicenter on the opposite side of Earth	True
Seismic P-waves can be detected worldwide from any strong epicenter.	True
Early telescopic observers thought the lunar mare were seas of water; today we know they are not liquid water but molten basalt, long ago frozen out.	True
Today most scientists favor the capture theory of the Moon's origin, since it would explain why the Moon still orbits in the ecliptic plane, as do other planets.	False
Aristotle was the first to propose that all planets revolve around the Sun	False
During retrograde motion, planets actually stop and move backwards in space	False
Copernicus's theories gained widespread scientific acceptance during his lifetime.	False
Galileo's observations of the sky were made with the naked eye	False
The Milky Way galaxy is about one million times larger than Earth.	False
The stars in a constellation are physically close to one another.	False
A lunar eclipse can occur only during the full phase.	True
The angular diameter of an object is inversely proportional to its distance from the observer.	True
As you drive away from a radio transmitter, the radio signal you receive from the station is shifted to longer wavelengths.	True
Gamma-ray telescopes employ the same basic design that optical instruments use.	False
One of the primary advantages of CCDs over photographic plates is the former's high efficiency in detecting light	True
The main advantage to using the HST is the increased amount of "night time" viewing it affords	False
The total mass of all the planets is much less than the Sun	True
Because of tidal forces, the Moon is in a synchronous orbit around Earth	True
Lunar maria are extensive lava-flow regions.	True
Earth's magnetic field is a result of our planet's large, permanently magnetized iron core.	False
Mercury's solar day is longer than its solar year	True
There is strong circumstantial evidence that active volcanism continues on Venus.	True
Valles Marineris is comparable in size to Earth's Grand Canyon	False
Storms in the jovian planets' atmospheres are generally much longer lived that storms on Earth	True
All four jovians spin faster than any of the terrestrials.	True
Jupiter's Great Red Spot is similar to a hurricane on Earth.	True
The Galileo probe into Jupiter's atmosphere found more water than expected.	False
We have observed a comet strike Jupiter.	True
Aurorae like ours have been seen above the poles of Jupiter and Uranus.	False
