Is this also based on spy satellites like Hubble (which is heavily related to the KH-11 ones of the Keyhole program)?

I still don't understand it 100%: Doesn't the much bigger field of view of roman mean, that a hubble sized part of it would end up with much less light for the same area? Can the bigger sensors compensate this completely?

An important point here is why it has a larger fov is not just the sensor, but also the smaller focal length. They are both brilliant telescopes, but they will be used slightly differently with the different fov's and focal length (57 vs 19 meters respectively). Which is still a crazy amount for roman. What makes roman so amazing is not just the fov, but also how fast the optics are (can gather a lot of light in a shorter amount of time) at an f/7.9 focal ratio compared to Hubbles f/24. So the fast optics and fov will make for an incredible telescope that scan large patches of the sky in a shorter time.

@WyomingMtnMan 　23일 전

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.

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 ?

However I will say the company was well ahead of the curve for chip design. They made a 4K sensor and camera in the early 2000s.

So if their stuff is on there it, I was probably their during the preliminary stuff but the sensors would have amazing quality.

You can increase the distance from the reflection to where the sensors are (camera)

To get a larger seperation of light waves to the same size sensor layout...

So the further from the aperture the sensors are the better the data we actually kind of get from the same (new) sensors

[ytcid:UgzdsttwQbF8fFDt27Z4AaABAg] You can increase the distance from the reflection to where the sensors are (camera) To get a larger seperation of light waves to the same size sensor layout... So the further from the aperture the sensors are the better the data we actually kind of get from the same (new) sensors

I don't understand how the same mirror can collect more data at the same resolution and dimness just because of the camera. Do the Hubble cameras only record a tiny percent of the available information coming from the mirror? ALSO--and I realize the degree to which images overlap may influence this--but in one place you say the Roman can do 100 times what the Hubble does, in another 12 times (17 months vs 17 years) and in another 1,200 times (one month vs 100 years) and I don't understand that, either.

@bert.pasquale 　24일 전

Ironically, Hubble’s total field of view is greater than Roman’s WideField Instrument. The catch is Hubble is based on a two-mirror Ritchie-Chrétien optical design which corrects for spherical, coma, and astigmatism, but cannot correct for field curvature. The prime focal plane is picked off by five separate instruments, plus three outlying fine guidance instruments. The entire focal plane spans over 1° field of view. But each instrument has a tiny field of view which is relayed to their individual sensors where the limited field curvature (and Hubble’s residual spherical aberration error) are corrected as needed.

Roman uses a Three Mirror Anastigmat optical design, which allows for a large, flat corrected image plane at prime focus — the perfect place to have 18 sensors covering the equivalent of a ~0.8° x 0.4° field of view! ???

I don't know if it applies to these two telescopes, but couldn't you also have a different focal length for the mirror? Like for a camera you could have a zoom lens or a wide-angle lens which are both about the same size, one just bends the light a lot more. You can do that with mirrors too, like those bathroom mirrors on an arm where one side is pretty flat and the other is more curved so it magnifies the reflection.

The Hubble had a computer Intel *_486!_* Pretty archaic today. Maybe the Roman won't need spectacles after it goes up.

When the Hubble was first launched in 1990, it was discovered that the primary mirror suffered from spherical aberration, meaning it had been ground to the wrong specifications. This meant that many of the images it captured in its first three years were fuzzy. A servicing mission in 1993 corrected the problem.

If Hubble captured less than 1% (0.1% according to the article shown) in 36 years - it is impossible to say that the 12% Roman may capture in 17 months would have taken Hubble 17 years (halfway the video). It is more correct what you state at the end of your video: it would have taken Hubble over a century to do so.

a little constructive criticism: you use several different comparison that contradict each other.

Now i *think* i know what you mean and why hubble has only taken less than 1% in 36 year (long exposure images is my guess) but using so many comparison that all seem to go against each other might lead to people who are not familiar to be more confused. Anyways im excited so lets absolutely launch ’em and get some beautiful data and pictures ?

Bear in mind that when NASA still had space shuttle they did upgrade Hubble, few times, with better instruments (not the initial optics correction)

If shuttle or other still existed we might have updated Hubble. Of course there will be limitations.

As the one which launched space telescopes, Hubble deserves to be preserved up there (safley parked in a higher orbit, probably).

Can't help thinking back to the earliest demonstration of a CCD (charge coupled device) on BBC TV's *Tomorrow's World* ... over a half century ago now.

This information is not entirely correct. Even though they have the same diameter, the telescopes have different focal lengths. It is this—not the greater number of sensors—that allows for a wider field of view and a larger illuminated area. Roman is f/8, I think, compared with Hubble’s f/24.

No. It's not just the sensor(s). The mirrors are shaped to different focal lengths. So, just like when you change lenses on a DSLR, a long focal length gives more magnification and a small field of view, whereas a short focal length gives less magnification and a larger field of view.

Yes, the size of the sensor makes a huge difference, but it's not the only factor.
