Intro To Astronomy
This imaginary construct includes the celestial north pole, the south celestial pole, and the celestial equator.
What is the celestial sphere?
He developed the first scientific mode of the solar system.
Who is Ptolemy?
The rate of change in velocity.
What is acceleration?
When we say light in astronomy, we are talking about this.
What is the EM spectrum?
These are the two main properties of a telescope.
What are light gathering power and angular resolution?
A cycle which includes new moon, first quarter, full moon, third quarter, waxing and waning crescent and waxing and waning gibbous.
What are the phases of the moon?
He developed the first Sun-centered scientific model of the solar system.
Who is Copernicus?
The principle that energy can not be created or destroyed, it can only change forms.
What is conservation of energy.
A particle of light is called this.
What is a photon?
This type of telescope use lens to focus light.
What are refracting telescopes?
Without this, the Earth would not have seasons.
What is axis tilt?
Kepler used his data to formula the laws of planetary motion.
Who is Brahe?
This principle explains why the Moon is moving away from Earth because of the slowing of Earth's rotation.
What is conservation of angular momentum?
This is the reason something moving away from us looks redder.
What is doppler shift?
These type of telescopes use mirrors to focus light.
That are reflecting telescopes?
Because of this, the further away a star is, the further we look back in time.
What is the speed of light?
He used a telescope to discover sunspots and moons around Jupiter.
Who is Galileo?
This force keeps the planets in their orbits.
What is gravity?
This can be determined using the peak wavelength emitted by an object.
What is temperature?
The three main types of science done with telescopes are imaging, light-curves, and this.
What is spectroscopy?
This occurs when the Moon is at one of the two nodes which interacts with the Earth-Sun plane, the Moon's phase is new, and the Moon is at its closest approach to Earth.
What is a solar eclipse?
His theory of gravity confirmed Kepler's laws.
Who is Newton?
This movement on Earth is caused by the interaction of the Sun's and Moon's gravitational pull.
What are tides?
This graph of stellar luminosity vs temperature allows us to classify stats.
What is the HR diagram?
This is a technique that uses multiple telescopes to simulate a larger telescope.
What is interferometry?
