It’ll be able to image actual planets and do a spectral analysis to determine its composition. So cool

Here's an example of the difference in area the Nancy Grace Roman telescope will be able to cover in a single capture versus Hubble, despite having a primary mirror the same size. Keep in mind, this is an unused National Reconnaissance Organization satellite. This was an outdated spy satellite design that originally would have been pointed at Earth.

Using gravitational microlensing to find exoplanets is amazing. I had no idea we had technology sensitive enough for that. That should unlock way more planets, because they won't have to be aligned so precisely in their orbits relative to us.

I wonder if we'll finally discover intelligent life on Earth
