The iconic NASA's Hubble Space Telescope image made the Pillars of Creation famous but now Webb appear to be able to look right through the dust and clouds

‘Bit of Panic’: Astronomers Forced to Rethink Early JWST Findings
Revised calibrations for the James Webb Space Telescope’s instruments are bedeviling researchers studying the distant universe
https://www.scientificamerican.com/arti … -findings/
Astronomers have been so keen to use the new James Webb Space Telescope that some have got a little ahead of themselves. Many started analysing Webb data right after the first batch was released, on 14 July, and quickly posted their results on preprint servers—but are now having to revise them. The telescope’s detectors had not been calibrated thoroughly when the first data were made available, and that fact slipped past some astronomers in their excitement.

The revisions don’t so far appear to substantially change many of the exciting early results, such as the discovery of a number of candidates for the most distant galaxy ever spotted. But the ongoing calibration process is forcing astronomers to reckon with the limitations of early data from Webb.

Figuring out how to redo the work is “thorny and annoying”, says Marco Castellano, an astronomer at the Italian National Institute of Astrophysics in Rome. “There’s been a lot of frustration,” says Garth Illingworth, an astronomer at the University of California, Santa Cruz. “I don’t think anybody really expected this to be as big of an issue as it’s becoming,” adds Guido Roberts-Borsani, an astronomer at the University of California, Los Angeles.

Calibration is particularly challenging for projects that require precise measurements of the brightness of astronomical objects, such as faint, faraway galaxies. For several weeks, some astronomers have been cobbling together workarounds so that they can continue their analyses. The next official round of updates to Webb’s calibrations are expected in the coming weeks from the Space Telescope Science Institute (STScI) in Baltimore, Maryland, which operates the telescope. Those updates should shrink the error bars on the telescope’s calibrations from the tens of percentage points that have been bedevilling astronomers in some areas, down to just a few percentage points. And data accuracy will continue to improve as calibration efforts proceed over the coming months.

Webb and Hubble Peer Into the Wreckage of a Galactic Collision

https://www.universetoday.com/158312/we … collision/

Earlier this month we asked, what could be better than a pair of galaxies observed by a pair of iconic space telescopes? Now, there is an exciting new answer.  Even better than a pair of galaxies is a pair of galaxies that are colliding!
