Honestly I would be shocked if this wasn't true. How many decades of advancement was there between Hubble and JWT? It better show us more, lol.

In terms of the JWST instruments? Not actually that long, maybe 15 years? JWST was already on the "drawing board" when Hubble was launched. The decades between JWST & Hubble were mostly working out the proving of the engineering origami i.e. folding it up into a rocket fairing, surviving the launch vibration of the solid rocket boosters, then unfurling successfully after parting company from the launch vehicle. The mirror on JWST gives a huge advantage in speed of observation, so tens of days for Hubble to collect light is now half a day & the things it can resolve are a fair bit better (witness the observations of planets in the solar system for example, or the Ultra Deep Field).

But mostly it operates in a different part of the spectrum, which is a game changer when comparing what JWST can reveal when looking at the same area of the sky as Hubble did.

Stupid headline. It's a different instrument observing at different wavelengths. Hubble can see plenty that Webb is blind to.

Thanks for the correct information, is there a way to report this post and have it corrected for misinformation?

Such as?

Anything that primarily radiates in the UV spectrum.

Hubble can image from far UV through near IR. Webb can make observations in orange light through mid-IR. Hubble is blind to light longer than 2500 nm. Webb is blind to light shorter than 600 nm. The instruments are not competitors. Their observations complement one another.

I mean, that's why it can see something that Hubble can't? It's not wrong.

Why is anyone surprised that a more advanced telescope is showing more detailed images?

In 20/30 years, there will be another telescope that will make JWT look like the Hubble.

I am not downplaying the JWT in the slightest, I am sure it will do great things.

Is anyone saying they’re surprised? I think we’re just amazed by the level of detail they achieved with JWST. It just so happens that it’s a lot more detail than the ~30 year old Hubble

It's in the title. "...finding things that Hubble didn't." That seems dismissive of Hubble's accomplishments.

I mean factually speaking, hubble didn’t see those things. Should they sugarcoat it to spare Hubbles feelings? I’m confused what you’re upset about 😂

Oh yay, another misleading and factually incorrect headline/article.

JWST literally sees wavelengths of light that Hubble is blind to and vice versa. Yes, JWST has higher resolution, but visible light =/= infrared light.

Anything longer than just a year or two would make a big difference.

Tech is evolving so very quickly.
