An instrument that makes a far away object
look nearer by collecting and focusing light.
Allows us to see more details that we can
see with our eyes only.
What is a TELESCOPE?
A type of telescope that uses lenses to
collect and focus light.
What is a REFRACTOR or a
REFRACTING TELESCOPE?
A type of telescope that uses mirrors to
collect and focus light
What is a REFLECTOR or a
REFLECTING TELESCOPE?
The part of a reflecting telescope that
reflects and focuses light
What is a MIRROR?
The part of a telescope that opens and closes to
let light shine through
What is the SHUTTER?
Made of our one star the Sun, and all the
planets and their moons which orbit the Sun.
What is our SOLAR SYSTEM?
A chunk of material (usually rock) that
travels in a circle around a planet.
What is a MOON?
A chunk of material (can be rock or gas) that
travels in a circle around a star.
What is a PLANET?
A massive ball of gas that shines
brightly because of the huge amount of
energy that is produced inside it.
What is a STAR?
A force that pulls all things together
What is GRAVITY?
A huge explosion that releases gas and
dust. One of the ways a massive star
can end its life.
What is a SUPERNOVA?
A giant cloud of gas and dust
What is a NEBULA?
A collection of many billions of stars, gas and dust
(including nebulae), all held together by the force
of gravity.
What is a GALAXY?
Earth and our solar system are part of
this galaxy. All the stars visible in the
night sky are part of our ‘home’ galaxy.
What is the MILKY WAY?
Made of billions of galaxies. All the galaxies
you could see are part of it.
What is the UNIVERSE?
The opening in a telescope through which light
enters.
What is APERTURE?
The amount of light that was collected by the
telescope from part of an object. Measured
as “pixel value” from an image using
MicroObservatory Image software.
What is BRIGHTNESS?
The range of brightness (pixel value) that we
choose to display in an image. We don’t HAVE to
display the WHOLE range of brightness in an
image.
What is CONTRAST?
The part of a telescope that collects the focused
light and records it as an electronic image
What is a DETECTOR?
The amount of time that the shutter stays
open
What is EXPOSURE TIME?
Short for “picture element.” The smallest
square portion of an electronic image where
light was collected by each part of the
detector
What is a PIXEL?
A tool that uses colors to represent the
brightness of pixels in an image
What is FALSE COLOR TABLE?
Extra brightness in an image that did not
come from light from an object, usually from
the detector electronics.
What is NOISE?
A tool that makes clearer the edges between
nearby regions of high and low brightness
What is SHARPEN?
A tool that takes away the parts of an image
around a chosen area
What is CROP?
