More First-Light Data From Herschel Space Telescope 21
davecl writes "First-light images and spectra have now been released for all three of the instruments on Herschel. (The first images came out a couple of weeks back.) The news is covered on the BBC, on the ESA website, on the Herschel mission blog, and elsewhere. The data all looks fantastic, and is especially impressive since the satellite was only launched about 7 weeks ago. I work on the SPIRE instrument and help maintain the blog; but even I am astounded by the amount of information in the SPIRE images."

Hubble works in the optical at wavelengths more than 100 times smaller than those Herschel is using, so it's not surprising you can see more detail. However, the Herschel images aren't showing stars at all, they're showing cool dust, just 50 or so degrees above absolute zero, material that Hubble just cannot see at all (and to be fair, Herschel can't see the stars that Hubble can see).
Trying to compare Hubble with Herschel is like comparing a fire with a bucket of liquid nitrogen.
