[ytcid:Ugzf1S4SHWvQ2U6FCGt4AaABAg] Thanks for telling us all about the Roman telescope. I really appreciate the way that you present information.

[ytcid:UgyVQjenwSy9UWRrw7t4AaABAg] Why is it. When we/you/them talk about Pluto, nothing is said about Charon?

[ytcid:UgzRgLLOlvQLwUGRN3t4AaABAg] There will probably be hiccups and limitations as it starts. Do you have any anticipation of what these are and how long we expect to go through some kind of calibration or troubleshooting phase yet? Obviously we hope everything goes smoothly, but we do now live in a world of ship it now fix it later.

[ytcid:Ugz53v9n91gzT7ghkwJ4AaABAg] What if the launch vehicle blows up? Do they have a spare telescope?

[ytcid:Ugwf-Db42uu1LWoYFFl4AaABAg] So JWST is going to retire or continue to do it's work??

[ytcid:Ugx1KwjTFB91iScRB-N4AaABAg] funny thing is, that and another one were military telescopes then considered obsolete and donated to NASA. the Roman was easily refurbished for space observation, the second one however is very specialized for ground sp- I mean observation, and a lot of people think it would be great to send it to Mars, for example. we could map the surface with unprecedented level of detail, plan future missions and landing sites, it would be really really cool!

[ytcid:UgxBI5w6WKFvj0aLDj94AaABAg] Seems to be a very expensive way to determine horoscopes. ??? Sorry. I will see myself out. ❤

[ytcid:UgxduHMNaOj5xpsoqPB4AaABAg] I hope Roman doesn’t need glasses like Hubble did. Cuz, no Shuttle…

[ytcid:UgzWQd7l1FBsrktJshZ4AaABAg] Very interesting and enjoyable, but "how sharp of an image"? Is that even English? I reckon you've spent too much time in the US.

[ytcid:Ugz06AGneZwCwyt4Pbl4AaABAg] Genuine question has Hubble received any damage in its illustrious history? Micro meteorites, tiny space debris, maybe particles hitting its detector and permanently damaging a pixel or two? Or is it still as pristine as the day it was at least repaired ? love your videos. Always so well explained and put together so thank you ?

[ytcid:Ugxa7de6DiU_2rAs4y54AaABAg] A couple of telescope parameters you didn't mention - focal length and f-ratio. Focal length is how much a telescope magnifies. The Hubble has a focal length of 57.6 meters while the Roman has a focal length of 18.96 meters, so Hubble magnifies more than Roman. The Hubble produces an image of a given object about 3 times larger than Roman. On Hubble, 1 arc minute of sky is spread over 16.8 mm on the sensor where Roman is only 5.5 mm. Think of a 300mm versus 28mm camera lens. However, to compensate for shorter focal length, Roman has smaller pixels than Hubble, sampling the image provided by the mirror more finely and making it able to resolve objects in the near infrared similar to Hubble. That leads to f-ratio, which is how efficient the telescope is at gathering light. It is calculated by dividing the focal length by the diameter of the mirror. Hubble has an f-ratio of f/24 while Roman has an f-ratio of f/7.9. Roman has approximately 9 times higher light concentration per pixel than Hubble and why it can image much faster than Hubble. The resolution is the same because the mirrors are the same diameter. Resolution depends on the wavelength of light and the diameter of the mirror, specifically resolution = 1.22 x wavelength / Diameter. The field of view isn't controlled by just the sensor size (like she says), it's controlled by sensor size AND focal length. Because of the longer focal length of the Hubble, it only has a field of view (how much of the sky it sees) of 0.05 square degrees while Roman has a view of 0.28 square degrees, about 100 times larger. Plus, Roman has a much larger sensor than Hubble. Think a 4 x 5" sheet film versus a 35mm slide. So Roman gathers light much faster over a larger area than Hubble, and why Roman can complete a survey in 17 months that would take Hubble 17 years. For reference, the Hubble telescope was designed to resolve Cepheid variables (a very important tool for measuring cosmic distances) in nearby galaxies to calibrate the Hubble constant, the expansion rate of the universe. Hubble trades survey speed and wide coverage to achieve unrivaled spatial resolution in UV and visible light. Roman trades UV coverage and super-high optical magnification to capture Hubble-quality near-infrared resolution across vast swathes of space at unprecedented speed.
