Exploring the Mysteries of the Far Infrared: A Glimpse into the Unseen Universe

:telescope:Far infrared telescopes provide a unique view of the early Universe, allowing us to see through gas and dust to observe newly forming planets.

:sparkles:These telescopes operate in the mid and near infrared, revealing fascinating protoplanetary discs and star systems.

:earth_americas:Observations from far infrared telescopes help us understand the architecture of planetary systems and find planets in undetectable orbits.

:question:Why are there no far infrared telescopes currently in operation?

:cold_face:Cooling systems are crucial for far infrared telescopes to reach the extremely low temperatures required for optimal sensitivity.

What is the difference between near, mid, and far infrared?

—Near infrared covers shorter wavelengths close to visible light, mid-infrared covers longer wavelengths, and far infrared spans from approximately 25 to 450 microns.

Why do far infrared telescopes need to be in space?

—Far infrared light doesn't penetrate Earth's atmosphere, so space-based telescopes are essential to observe these wavelengths.

How do far infrared telescopes overcome the limitation of coolant requirement?

—Modern far infrared telescopes use mechanical cryo coolers instead of expendable onboard cryogens, allowing for longer mission lifetimes.

What can far infrared telescopes reveal about star and planet formation?

—Far infrared observations provide insights into the complex processes of star formation, from the collapse of Interstellar molecular clouds to the formation of planetary systems.

What objects in the universe emit most of their light in the far infrared?

—Objects like newly forming stars, protoplanetary discs, and dust-laden clouds emit significant amounts of their light in the far infrared, making it essential for studying these celestial phenomena.

00:00Far infrared telescopes offer a unique perspective on the early Universe, allowing observations through gas and dust to reveal newly forming planets.

04:00Telescopes operating in the far infrared require cooling down to extremely low temperatures for optimal sensitivity and reduced background noise.

10:00Far infrared observatories fill a gap in our coverage and provide critical information about star and planet formation processes.

13:00Far infrared telescopes penetrate through dust and gas clouds, enabling the study of objects that emit most of their light in this wavelength range.

14:30Far infrared telescopes reveal hidden wonders, such as the polar jets of protostars and the architectures of planetary systems.

16:00Space-based far infrared telescopes are essential because far infrared light does not penetrate Earth's atmosphere.
