Effect of Telescope Aperture Size on Spectrometer Resolution

AI Thread Summary
Telescope aperture size significantly impacts the resolution of a spectrometer, as the Airy Disc acts similarly to a slit in this context. The dimensions of the Airy Disc directly influence resolution, indicating that larger apertures can enhance clarity. Additionally, the f-number of the telescope is also a crucial factor affecting resolution. The relationship between bandwidth sensitivity and aperture size is emphasized, highlighting their interconnectedness. Understanding these dynamics is essential for optimizing spectrometer performance.

A spectrometer is sensitive to band width. Band width and aperature are definitely connected.
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
