Are those all stars in our own galaxy? I know the pillars are in our galaxy, but are all the stars in the image also?

More new discoveries that surprise astronomers, don't fit current theories very well.
In what James Webb Space Telescope researchers call a "whole new chapter in astronomy," the observatory has helped to locate two early galaxies, one of which may contain the most distant starlight ever seen. In a tweet, the international team said the unexpectedly bright galaxies could fundamentally alter what is known about the very first stars. "With Webb, we were amazed to find the most distant starlight that anyone had ever seen, just days after Webb released its first data," Rohan Naidu, of the Harvard-Smithsonian Center for Astrophysics and the Massachusetts Institute of Technology, told NASA of the more distant GLASS galaxy – referred to as GLASS-z12 – which is believed to date back to 350 million years after the big bang. "While the distances of these early sources still need to be confirmed with spectroscopy, their extreme brightnesses are a real puzzle, challenging our understanding of galaxy formation," the University of Geneva's Pascal Oesch said. https://www.foxnews.com/science/james-webb-space-telescope-researchers-uncover-early-galaxies-new-chapter-astronomy |

$10 Billion Webb Telescope Has Been Struck 14 Times By Space Rocks, Says NASA
When NASA sent the James Webb Space Telescope (JWST) a million miles from Earth last Christmas Day it did so with one major worry—micrometeoroids. These tiny particles of space dust have, predictably, already struck the $10 billion space telescope’s 18 beryllium-gold segments, causing irreparable damage not just once, but 14 times, NASA has revealed in a blog. “We have experienced 14 measurable micrometeoroid hits on our primary mirror, and are averaging one to two per month, as anticipated,” said Mike Menzel, Webb lead mission systems engineer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The resulting optical errors from all but one of these were well within what we had budgeted and expected when building the observatory.” The outlier happened in May, when a micrometeoroid struck one of the beryllium-gold segments that makes up JWST’s main 6.5-meter mirror. Classed as as “unavoidable chance event,” it knocked the telescope slightly out of alignment. Engineers were able to adjust its 18 mirrors to correct for the damaged segment. Space is a dangerous place to operate, with constant threats including cosmic rays from the Universe at large, harsh ultraviolet light and charged particles from the Sun, and micrometeoroids traveling at extreme velocities. However, JWST’s engineers are already taking evasive action to reduce the chance of the precious space telescope from being damaged further. A working group at NASA concluded that strike in May 2022 was a rare statistical event, but the massive space telescope will hence be faced away from what is now known as the “micrometeoroid avoidance zone.” That means minimizing the time it spends looking in the direction of orbital motion, which statistically has more micrometeoroids moving at much higher velocities. A particularly risky period is a meteor shower, which are caused by the particles left in the inner solar system by casing comes. It’s a scenario that could become a live issue particularly in both May 2023 and again in May 2024 when Webb travels through Halley’s comet’s stream of meteoroids. “Micrometeoroids that strike the mirror head on (moving opposite the direction the telescope is moving) have twice the relative velocity and four times the kinetic energy, so avoiding this direction when feasible will help extend the exquisite optical performance for decades,” said Lee Feinberg, Webb optical telescope element manager at NASA Goddard. The upshot is a reshuffling of JWST’s schedule, with objects observed when it’s safest to do so rather than in order of scientific urgency. An exception to the will be solar system targets, which are far more time-sensitive. Webb—a $10 billion space telescope that sees in the infrared part of the spectrum—launched on Christmas Day in 2021 and has since February been orbiting the L2 point about a million miles/1.6 million kilometres from Earth.

JWST discovered PHOTOCHEMISTRY in an exoplanet's atmosphere (this is a BIG deal) ft. Dr. Jake Taylor Adorably energetic astrophysicist chick reporting that JWST has found evidence of photochemistry in exoplanet WASP-39b’s atmosphere: Using three of its instruments, the JWST was able to observe light from the planet’s star as it filtered through WASP-39b’s atmosphere, a process known as transmission spectroscopy. This allowed a team of more than 300 astronomers to detect water, carbon monoxide, sodium, potassium and more in the planet’s atmosphere, in addition to the carbon dioxide. The gives the planet a similar composition to Saturn’s, although it has no detectable rings. The team was also surprised to detect sulfur dioxide, which had appeared as a mysterious bump in early observation data. Its presence suggests that a photochemical reaction is taking place in the atmosphere as light from the star hits it, similarly to how the Sun produces ozone in Earth’s atmosphere. In WASP-39b’s case, light from its star, which is slightly smaller than the Sun, splits water in its atmosphere into hydrogen and hydroxide, which reacts with hydrogen sulfide to produce sulfur dioxide. “These spectra are just exquisite in their detail, and reveal an additional way that the star affects the planet’s atmospheric composition, through photochemistry,” says Victoria Meadows, an astronomer at the University of Washington in Seattle. “Photochemistry, because it is such an important process here on Earth, is probably an important process on other potentially habitable planets,” says Jacob Bean, an astronomer at the University of Chicago in Illinois and the observation team’s co-leader. Until now, “we’ve only been able to test our understanding of photochemistry in our Solar System. But planets around other stars give us access to completely different physical conditions.” View Quote https://www.nature.com/articles/d41586-022-03820-3 |

There were a lot of cost overruns with JWST, and in the end, it cost $10-billion over 17 years.
Sounds expensive, but really, that's pretty cheap compared to the money we're throwing at things like Ukraine right now. We should have built 5 of the damn things and launched them all up at once. |

Webb is representative of the NASA way of doing things. That way of doing things can be impressive but I believe that we are going to see some pretty dramatic changes soon with launch costs finally trending downward.
JWST's successor: The Carl Sagan Observatory - a 12 METRE optical telescope searching for exo-Earth It would be interesting if the Carl Sagan Instrument is launched, but I don't expect it to be. With the new generation of launch vehicles on the drawing board I anticipate there will be changes to the design of future space telescopes. Instruments built to be a bit more rugged as opposed to having to shave every single possible gram of weight. |

View Quote Even if they make it more rugged, they'll shave every excess gram of weight possible. They'll be using less than ideal mirror surfaces now that the density/frequency of micro-meteors is known (if that is their reason and not blotting out something they don't want us to see ) I'm not so sure we'll learn more, though we've already learned that what was thought as 'known science' isn't correct since looking back so far (through time), they see more and more galaxies rather than the void before "big bang". They haven't really dumped any new images of their super deep looking images have captured, other than the first one that says "this is supposed to be empty space right after Big Bang, but it is full of galaxies" so they're scratching their heads. |

Exactly! once I saw the Hubble deep field images after they were published, I had a strong feeling that if they ever built a telescope that could see much further, that this would be the case. I'm curious how they will change their interpretations based on all this new data. |

While I think they were trying to be "book smart" using a Lagrange Point for the telescope, I think they are finding that it is a garbage collection point more suited for a hardened space station which sucks. I hope that their "aim it at nothing solution" works, but I think that will only help somewhat and it will have a much shorter life than planned

Like waves around water spiraling down a drain, but I'm not sure if gravity "piles up" to make waves of higher and lower intensity at that scale. Maybe that's why they're studying spiral galaxies. Really pretty to look at and only a guess at the mechanisms but thousands and tens of thousands of light years between the edges is a mind numbing scale to try and compare anything we have relation to, Earth would just be another pixel in one of those dust strands with how small we are and how huge these galaxies are. |
