What Does Electromagnetic Radiation In The Universe Show Us?

Episode 4 of 5



Radio, infrared, X-ray, and Gamma ray telescopes are continuing to unveil things in our universe we couldn't have imagined would be there. What are we going to find next?

Our Solar System:

“We aim radio telescopes at the Sun, planets, moons, and planetesimals in our Solar System. Used as telescopes, they tell us about the temperature, composition, and magnetic activities of these bodies."

Radio Telescope:

“In contrast to an ‘ordinary’ telescope, which receives visible light, a radio telescope "sees" radio waves emitted by radio sources, typically by means of a large parabolic ('dish') antenna, or arrays of them."

Our Galaxy:

“On a clear, dark night, you can see a glowing stream that seems to split the sky. We have called it the Milky Way for thousands of years, and its exact nature was a mystery until less than a hundred years ago."

IR Astronomy: Overview:

“Infrared Astronomy is the detection and study of the infrared radiation (heat energy) emitted from objects in the Universe. Every object that has a temperature radiates in the infrared. So, Infrared Astronomy involves the study of just about everything in the Universe."

Spitzer Space Telescope:

“Spitzer Space Telescope, U.S. satellite, the fourth and last of the National Aeronautics and Space Administration fleet of 'Great Observatories' satellites. It was designed to study the cosmos at infrared wavelengths."

About the Hubble Space Telescope:

“From the dawn of humankind to a mere 400 years ago, all that we knew about our universe came through observations with the naked eye."

X-ray Telescopes:

“Creating a telescope to image and focus X-rays might seem like it should be an easy task. After all, scientists focus light all the time."

[ParadigmFlux]

an episode explaining all the math and science that brought us to the point where we have modern smart phones would be amazing. these devices, to me, are like possessing a magic wand. Its mind blowing what these devices are capable of doing. Any one from the eighteenth century would think we were wizards if they traveled to our time.

[SpartaSpartan]

Would it be possible to build a gravitational wave telescope?

[AtheistRex]

Hey! Hubble is not solely optical! It has IR and UV capabilities as well.

[yourfriendlyneighbourhoodh]

You guys should do a series on electricity

[happygolucky]

Yes, I've enjoyed Cosmos with Neil DeGrass Tyson, too.

[nicosmind]

Fun fact about Jupitor. If you could see its elecromagnetic sphere in optical light, it would strech out so far from the planet it would appear as large as the moon as seen from Earth!!!

[thecodgamer]

Do a series on galaxies and/ or the universe

[rajeevsrivastava]

I want to know how these radio signals originate ?

[CFUX]

could you put say one telescopes infront of another and magnify that image ?

[danieljamieson]

if the universe is expanding, where is the center?

[racks]

So I saw comment on if there was a very large mirror on the other side of the galaxy, we would be able to see the very first stages of earth. I know how that would work but I want an in depth explanation instead.

[danielray]

You really need to show some pictures :)

[kushalthakur]

can gamma rays pass through black holes ?

[natesmith]

If we found a mirror on the other side of our galaxy could we see dinosaurs or the beginning of our planet

[violencia]

There needs to be a shirt that says "Light Buckets".

[aaexo]

You missed microwave and ultraviolet telescopes >:-|

[suryab]

trace why dont you try something about Hawking....Cause i learn only from you bro

[PsicoJoyceGonzalez]

Will I be able to watch telescope in Mexico?

[metecloche]

Aaah Kos or some say Kosm. Do you hear our prayers ?

[HalleyRai]

just imagine guys..all the things we see from telescope has already happened millions of years ago..we are seeing the past...aka time travel through light hahaha...there might already destruction of universe happening but we wont know..
