How Do Space Telescopes Break Down Light?

Space telescopes like Hubble and our upcoming James Webb Space Telescope use light not only to create images, but can also break light down into individual colors (or wavelengths). Studying light this way can give us a lot of detail about the object that emitted that light.  For example, studying the components of the light from exoplanets can tell us about its atmosphere’s color, chemical makeup, and temperature. How does this work?

Remember the primary colors you learned about in elementary school?

Those colors are known as the pigment or subtractive colors. Every other color is some combination of the primary colors: red, yellow, and blue.

Light also has its own primary colors, and they work in a similar way. These colors are known as additive or light colors.          

TVs make use of light’s colors to create the pictures we see. Each pixel of a TV screen contains some amount of red, green and blue light. The amount of each light determines the overall color of the pixel. So, each color on the TV comes from a combination of the primary colors of light: red, green and blue.

Space telescope images of celestial objects are also a combination of the colors of light.

Every pixel that is collected can be broken down into its base colors. To learn even more, astronomers break the red, green and blue light down into even smaller sections called wavelengths.

This breakdown is called a spectrum.

With the right technology, every pixel of light can also be measured as a spectrum.

Images show us the big picture, while a spectrum reveals finer details.  Astronomers use spectra to learn things like what molecules are in planet atmospheres and distant galaxies.

An Integral Field Unit, or IFU, is a special tool on the James Webb Space Telescope that captures images and spectra at the same time.

The IFU creates a unique spectrum for each pixel of the image the telescope is capturing, providing scientists with an enormous amount of valuable, detailed data. So, with an IFU we can get an image, many spectra and a better understanding of our universe.

Watch the full video where this method of learning about planetary atmospheres is explained:

The James Webb Space Telescope is our upcoming infrared space observatory, which will launch in 2021. It will spy the first galaxies that formed in the universe and shed light on how galaxies evolve, how stars and planetary systems are born and tell us about potentially habitable planets around other stars.

Really love how this turned out. Love the color blends. Had a really fun time making it. #dragonoftheday #dragon #dragonvale #DICEDRAGON #polymerclayart #polymerclaydragons #pocketdragons #skinnerblend #spiritanimal #rainbowdragon #rainbow #roygbv #colorpop https://www.instagram.com/p/B1TBv0tAF4F/?igshid=w1zgpj4tqf5m

Times New Roman with the font size 14 is really helpful when you’re trying to memorize things. It also helps if you organize what you are trying to memorize in the ROYGBV (Red, Orange, Yellow, Green, Blue, Violet) format. So the first couple sentences might be red, the second couple sentences might be orange, and so on. Hope this helps!

OH BOY HERE THEY ARE! The main cast for a project I’ve had for a couple of years now called ROYGV (Roy-gee-beev).

The plot is in the process of changing a bit from what it originally was, but in essence it stays the same: A group of rainbow-colored animals saving their land from a catastrophe that renders the world and its residents monochrome!

This was planned to be a RPG game of sorts, but atm I dunno what it’ll be. 

Little bio snippets below!

Rana

A panda from the Akai Kingdom. She’s the main character and the one who originally plans to save the land. Her main equipment is caps.

Oxford

A lizard from the Laranxa Kingdom. He was the apprentice of a respected inventor before they were afflicted with the monochrome condition. His main equipment is glasses.

Yoko

A rabbit from the Huángsè Kingdom. Was a tomb raider with his older brother, Yarrow, but Yarrow was killed in a cave-in. His main equipment is scarves.

Grendaine

A cat from the Berdea Kingdom. A patient with a terminal illness that made her lose a good portion of her fur. Her main equipment is coats.

Bauble

A bird from the Modrý Kingdom. Actually the son of said kingdom’s ruler, but doesn’t want to be babied anymore. His main equipment is vests.

Paula

A bat from the Karmrel Kingdom. Apparently the only survivor of the monochrome calamity in her kingdom. Her main equipment is bows.

Muddlebug

A species of robot insect that suddenly started showing up after the calamity. They act largely as a group and rely on instructions from their leaders.

Qpaqua and Cleari

The leaders of the Muddlebugs. They constantly switch between working well together and arguing. Want to sap the color away from the land of Chroma.

The Rose Unit

A rogue Muddlebug who somehow got a lovely coat of paint. They seem to lack any connection to the rest of the Muddlebugs, and is often said to have ‘malfunctioning programming’ by the others.
