I think a big reason Hubble managed to do that was that it captures in the visible spectrum due to being a repurposed spy satellite. That spectrum just isn't that interesting these days afaict, especially since ground based observatories have gotten a lot better at seeing through the earth's atmosphere. The false color images of most of today's missions are just a lot harder for the public to understand. It was also launched in a time where NASA desperately needed good publicity.
