Title: ERS observations of the Jovian System as a demonstration of JWST capabilities for Solar System science
https://jwstfeed.com/PostView/FeedPost? … nrcb4_rate
Instrument: NIRCAM/IMAGE (F212N)

In the annotated image you can see a central structure resembling a keyhole, filled with dense clumps of gas and dust from a supernova blast. The dust is so dense that even near-infrared light that Webb detects can’t penetrate it.

Seen here by Webb's Mid-Infrared Instrument (MIRI) is the galaxy M51, also known as NGC 5194. The gravity of its neighbor, the dwarf galaxy NGC 5195, is thought to be partially responsible for those prominent & distinct spiral arms!

I don't want to say JWST has found a 'chemistry' of exo world alien life news ....but maybe...there is a chemical sign of life.

and also

Re: James Webb Space Telescope (JWST) - 6.5m mirror, L2 orbit

Seti Fermi news

A group of Astrobiologists have proposed a new method to establish when observations of exoplanet atmospheres really is evidence of extraterrestrial life.

https://phys.org/news/2023-09-youve-ali … y-nwletter

The central problem they are trying to tackle here is that as we don't know the many possible biochemical permutations life might have elsewhere in the Universe, how can we be sure about claims about observations of gasses in exoplanet atmospheres. This was in the news this week with the discovery of dimethyl sulphide on the watery planet K2-18 b. By the end of the decades there may be hundreds of such observations.

The method they propose is one that has been used in climate change science - collating expert opinion from thousands of scientists and going with what is most strongly supported. It's not a perfect solution either, but as we're forced to operate in any environment of incomplete data ( we don't know the full range of potential alien biology) - it may have to do for now.

A young star is born?

NASA’s James Webb Space Telescope’s high resolution, near-infrared look at Herbig-Haro 211 reveals exquisite detail of the outflow of a young star, an infantile analogue of our Sun. Herbig-Haro objects are formed when stellar winds or jets of gas spewing from newborn stars form shock waves colliding with nearby gas and dust at high speeds

Re: James Webb Space Telescope (JWST) - 6.5m mirror, L2 orbit

The Universe is bigger and older than it should be and the numbers don't add up? GLASS-z13 a Galaxy 300 million years after the 'BigBang'  also JWST finds candidates for an active supermassive black hole even earlier in the universe’s history should have. CEERS-93316 was measured to have a light-travel distance (lookback time) of 12.6 billion years, and, due to the expansion of the universe, a present proper distance of 25.7 billion light-years. the first 700 million years seem to be up to 100 times more massive than standard cosmological theories predict. HD1 is a proposed high-redshift galaxy, which is considered (as of April 2022) to be one of the earliest and most distant known galaxies yet identified in the observable universe. Up until the discovery of JADES-GS-z13-0 in 2022 by the James Webb Space Telescope, GN-z11 was the oldest and most distant known galaxy yet identified in the observable universe,  a spectroscopic redshift of z = 10.957, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs).  Rajendra Gupta at the University of Ottawa based on data from the James Webb Space Telescope (JWST) and using the controversial 'Tired Light' suggests that the universe may be twice as old as previously thought.

Perhaps why Cosmology is considered a branch of metaphysics and fringe science like 'String Theory' and philosophy rather than true physics and mathematics.

Once again JWST finding strange observations. The Universe seems to be older than it should be?

Discovery of ‘Jumbos’ may herald new astronomical category
https://www.theguardian.com/science/202 … l-category

James Webb Space Telescope Has Spotted Something Lurking in the Orion Nebula That “Shouldn’t Exist,” and They Come in Pairs
https://thedebrief.org/james-webb-space … -in-pairs/


Brown dwarfs & free-floating planet mass objects bunched together in Orion, protostar seen, 'Jumbos' telescope JWST and the 'JuMBO' discovery of planet-like objects inside Orion, young stars and proto-planetary disk

The rogue planet or free-floating planet (FFP), isolated planetary-mass object (iPMO), interstellar, nomad, orphan, starless, unbound or wandering planet) is an interstellar object of planetary mass which is not gravitationally bound to any star or brown dwarf.
https://web.archive.org/web/20081013054 … 403-1.html

Cha 110913−773444 (sometimes abbreviated Cha 110913) is an astronomical object surrounded by what appears to be a protoplanetary disk. It lies at a distance of 529 light-years from Earth. There is no consensus yet among astronomers whether to classify the object as a sub-brown dwarf (with planets) or a rogue planet (with moons)

Perhaps another object for JWST

Dark Matter Explanation?

Jupiter Mass Binary Objects or "JuMBOs

Jupiter-sized "planets" free-floating in space, unconnected to any star, have been spotted by the James Webb Space Telescope (JWST).

What's intriguing about the discovery is that these objects appear to be moving in pairs. Astronomers are currently struggling to explain them.

The telescope observed about 40 pairs in a fabulously detailed new survey of the famous Orion Nebula.

They've been nicknamed Jupiter Mass Binary Objects, or "JuMBOs" for short.

One possibility is that these objects grew out of regions in the nebula where the density of material was insufficient to make fully fledged stars.

Another possibility is that they were made around stars and were then kicked out into interstellar space through various interactions.

"The ejection hypothesis is the favoured one at the moment," said Prof Mark McCaughrean.

"Gas physics suggests you shouldn't be able to make objects with the mass of Jupiter on their own, and we know single planets can get kicked out from star systems. But how do you kick out pairs of these things together? Right now, we don't have an answer. It's one for the theoreticians," the European Space Agency's (Esa) senior science adviser told BBC News.

Photos snapped by the James Webb Space Telescope (JWST) have revealed the farthest-ever example of an "Einstein ring." The record-breaking halo of warped light, which is a whopping 21 billion light-years away, is unusually perfect and surrounds a mysteriously dense galaxy.

JWST Reveals Protoplanetary Disks in a Nearby Star Cluster
https://www.universetoday.com/164470/jw … r-cluster/
The Orion Nebula is a favourite among stargazers, certainly one of mine. It’s a giant stellar nebula out of which, hot young stars are forming. Telescopically to the eye it appears as a grey/green haze of wonderment but cameras reveal the true glory of these star forming regions. The Sun was once part of such an object and astronomers have been probing their secrets for decades. Now, a new paper presents the results from a detailed study from the James Webb Space Telescope (JWST) that has been exploring planet forming disks around stars in the Lobster Nebula.
