Telescope 1
Telescopes serve as 'buckets' to collect this.
What is light (electromagnetic radiation)?
What is the Hubble Space Telescope?
They are the two largest planets in our solar system.
What are Jupiter and Saturn?
It is the closest planet to our sun.
What is Mercury?
It is the approximate age of our solar system.
What is 4.5 billion years old?
It's a device that senses the radiation in the wavelength regions we have chosen and permanently records the observations.
What is a detector?
He was an Italian scientist who was the first to use a telescope to observe objects in space in 1610.
Who was Galileo?
This is the hottest planet in our solar system.
What is Venus?
It's a gaseous element that is in liquid form on Jupiter and Saturn.
What is hydrogen? or helium?
It is a spinning cloud of gas and dust which astronomers believe our sun and planets formed from.
What is a solar nebula?
They are, 1. To collect faint light from an astronomical source. AND 2. To focus all the light into a point or image.
What are the most important functions of a telescope?
Telescopes, that collect visible radiation, use these to gather the light.
What is a lens or mirror?
They are rocks made of silicon and oxygen, and they are abundant on terrestrial planets.
What are silicates?
It's the most common metal on terrestrial planets.
What is iron?
They are planets, observed in other solar systems, that are small than gas giants yet bigger than our terrestrial planets.
What are Superearths?
It is a transparent piece of material that bends the rays of light passing through it.
What is a lens?
It is an additional lens that one can look through to see the image produced by the telescope.
What is an eyepiece?
It is Saturn's largest moon.
What is Titan?
It is the process by which gravity helps separate a planet's interior into layers of different compostions and densities.
What is differentation?
They are the smaller precursors of planets.
What are planetesimals?
The most common type of telescope today which uses a mirror, rather than a lens, to form an image.
What is a reflecting telescope?
It refers to the precision of detail present in an image.
What is Resolution?
In a sense, they act as chemical fossils, helping us to learn about a time long ago whose traces have been erased on larger worlds.
What are asteroids and comets?
They are the two largest moons of Jupiter.
What are Ganymede and Callisto?
What is an opposite spin from the other planets in the solar system?
