It's exactly the same size as the Hubble Space Telescope.
The mirror, which is the thing that collects all of the light in, is 2.4 meters, same size as the Hubble, and that makes it a lot smaller than the James Webb Space Telescope.
But what differentiates it from both of them is its wide field of view.
So the Roman Space Telescope isn't going to be able to see as far into space as the James Webb Space Telescope.
It's not quite as powerful, but every snapshot.
It takes of the Cosmos is about a hundred times the size of what the James Webb Space Telescope can do.
So it's these much more wide-angled pictures, and they're also a lot wider than Hubble as well.
It also looks in a different part of the spectrum to the James Webb Space Telescope.
So it's slightly higher energy, infrared, and visible light.
So the idea is it's going to be taking these kind of big panoramas and looking for unusual stuff, stuff that changes quite quickly, like supernovas, and then theoretically stuff that the James Webb Space Telescope can zero in on a bit more.
Okay, so these telescopes will work together in essence.
Yeah, the idea is that they're designed to be really complementary.
There's three big ones.
The first two are dark matter and dark energy, these very, very weird physics phenomena that we don't fully understand, or we don't really understand at all.
One of the ways we can learn more about both of them is seeing how galaxies are distributed across the universe and how they're moving, because that will give us information about what's sort of driving them to move, the gravity and the energy.
that we can't necessarily see.
And so the Roman Space Telescope is going to be really good for this because it takes these big pictures with its wide field infrared instrument.
It's going to have these like really large galactic panoramas basically that can tell us a lot more about how they're all structured and shaped and basically theoretically builds up this kind of three-dimensional map of the universe.
So that's one of the things it's going to be really useful for.
The other big one is exoplanets.
