Sensor / Probe
Star Chart by Escape Velocity LimitedUses GPS technology to give an accurate 3-D simulation of the visible universe. By pointing your smart phone at any point in the sky, Star Chart can tell you what you are looking at.
Star Chart calculates in real time the current location of every star, planet and moon visible from Earth and shows you precisely where they are; eve in broad daylight!
You can point your device at a star and find out what star or
planet it is.You can find out what the night sky looks like to people on the other side of the earth by pointing the device down.
Accurately depicts the visible stars of the northern and southern hemispheres--a total of approximately 120,000 stars
You can fly to explore all the planets of the solar system, their moons and the sun all in beautiful 3D with state of the art visual effects
The Time Shift feature allows you to shift up to 10,000 years forward or backwards in time.
Displays all 88 constellations with constellation imagery based on artwork by 17th century astronomer Johannes Hevelius
Includes the complete Messier catalogue of 110 exotic deep sky objects.
Tap on anything in the sky and get the facts on what you are looking at, including distances and brightness
Manually set your location to find out what the sky looks like from anywhere in the world.
Sample Investigation
PLOTTING THE SPECTRAL CLASS OF THE STARS THAT MAKE UP YOUR CONSTELLATION ON THE HERTZSPRUNG-RUSSELL DIAGRAM
Mnemonic for Remembering the Spectral Classes
"Oh Be a Fine Girl/Guy, Kiss Me"
SPECTRAL CLASS OF A STAR HAS THREE ASSIGNED VALUES
for example K3III
LETTER -surface temperature of the star (O,B,A,F,G,K, AND M where O is the hottest temperature)
NUMERIC DIGIT-each letter is subdivided using a numeric digit with 0 being the hottest and 9 being coolest.
ROMAN NUMERAL-luminosity class 0, I, II, III, IV, V, sd, and D
0 hypergiants IV sub giants
I supergiants V main sequence star
II bright giants sd sub dwarfs
III regular giants D white dwarfs
HR Diagram
The Hertzsprung-Russell Diagram is actually a graph that illustrates the relationship that exists between the average surface temperature of stars and their absolute magnitude, which is how bright they would appear to be if they were all the same distance away. Rather than speak of the brightness of stars, the term "luminosity" is often used. Luminosity is a measure of how much energy leaves a star in a certain period of time
Provide a sample investigation that you conducted using the data collected by the probe/app. Include independent variable, dependent variables, constants and controls.
