What is infrared light?

A very general introduction to infrared astronomy, with links to go to for more information.

Central wavelengths and zero points

A reference page for bands frequently used in NITARP.

Units

Literature searching

How can I find out what scientists already know about a particular astronomy topic or object? Literature searching is an essential part of doing scientific research! Click this link to find out how.

What is a mosaic and why should I care?

need to chase sublinks and file them

Typically objects or regions in space we want to look at are too large for the telescope to capture in a single image or frame, so the telescope has to take many frames which are later combine using software into a single image or what is commonly called a mosaic. Click "mosaic" above for more details.

Resolution

Resolution matters for Spitzer images!

Diffraction

Diffraction matters for Spitzer images!

Confusion

Depending on where you are looking and what wavelength you are using and specifically what you are doing, confusion can matter for Spitzer images.

Infrared Background

Depending on where you are looking and what wavelength you are using and specifically what you are doing, the IR background can matter.

Telescopes

need better title, sorting
