It is, but is it a good idea to post papers prior to being peer reviewed?

Depends.

When there is this much new info pouring in, you cant accept everything as 100% correct. It's more like scientific brainstorming, but still following the scientific method.

This isnt something as serious as public health.

I guess, as long as the papers are just "observations" and some hypothetical conclusions based on that. But, if they are making any scientific claims, it could damage their reputation in the scientific community if they publish and are disproven later. I'm not complaining though, the more news and discoveries that come out, the better. I'm starving for some "educated guesses" as to what they are seeing.

Webb and Hubble capture spectacular image of heart of Phantom Galaxy

NASA released the first full-color images of our universe from James Webb in July. Since then, the space telescope has captured evidence of a supernova, carbon dioxide in an exoplanet’s atmosphere, and now James Webb has captured an image of a beautiful Einstein Ring........

An Einstein Ring is essentially when light from a galaxy or star passes another galaxy or a massive object en route to Earth. Because the large object’s gravity bends the light, it creates gravitational lensing. This creates a ring-life effect, making the galaxy’s light appear as a nearly perfect ring. In this new image, James Webb has captured the galaxy SPT-S J041839-4751.8.

The light from SPT-S J041839-4751.8 appears like an Einstein Ring because of a foreground galaxy that has bent the light from it. So, this new James Webb image of an Einstein Ring isn’t actually the galaxy that is creating the light. Instead, we simply see the light from that galaxy as it bends around the foreground galaxy..........

The James Webb Space Telescope (JWST) has captured its first images of an alien world – and because the telescope is performing 10 times better than expected, we are likely to see many more in future.

Astronomers have taken direct images of just 20 exoplanets, all from Earth-based telescopes. But because our planet's atmosphere blocks out a large number of features in the infrared range, it has been difficult to detect features of these planets in any great detail.

“Being here on Earth really sets a sensitivity floor to what we're able to detect, and to this day, the lowest mass planet we've been able to detect is about two Jupiter masses,” says Sasha Hinkley at the University of Exeter, UK.

Now, Hinkley and his colleagues have used JWST to directly image a so-called super-Jupiter exoplanet, HIP 65426 b, which is around seven Jupiter masses and orbits a star around 400 light years from Earth. The team captured it in a range of infrared wavelengths and at a precision that had previously been impossible.

“What we know from these observations is that JWST is going to shatter that sensitivity floor,” says Hinkley. Future observations should be able to go far below the mass of Jupiter, he says. “It's going to allow us to get down to planets that are analogues of ice giants in our own solar system. These might be things like Saturns, or possibly even Neptunes, if we're lucky.”..........

NASA's Hubble telescope captured a stunning spiraling star formation in the center of stellar nursery that sits 200,000 light-years away from Earth.

The young stars can be seen spiraling into the center of a huge cluster of stars known as NGC 346 located in the Small Magellanic Cloud, which is a satellite galaxy of our Milky Way and one of our closest galactic neighbors.

Researchers using the power of Hubble and the European Southern Observatory's Very Large Telescope say the outer arm of the spiral could be feeding star formation in a river-like motion of gas and stars.

The stellar nursery's unique shape has long puzzled astronomers. NGC 346 also boasts the mass of 50,000 suns. To put that into context, the sun is massive enough to hold about 1.3 million Earths inside of it.

It took the combined power of NASA's Hubble Space Telescope and the European Southern Observatory's Very Large Telescope (VLT) to unravel the behavior of this mysterious-looking stellar nesting ground...........

Nice photo.....until Webb takes aim at it. Hubble is still useful but is no longer the BMOC.

I think the term is BTIS

Big Telescope in Space

They should have named it BAT...Big Arse Telescope.

Just think 3-4 decades from now when the next telescope provides pictures that put Webb’s to shame

3-4 decades from now

When it comes to studying alien worlds, the James Webb Space Telescope could be drastically wrong, though not for any fault of its own.

That’s the finding of a new study by researchers who looked not at the Webb telescope’s optics, but at the models scientists use to interpret the findings after the telescope has made an observation.

Specifically, the models scientists use to understand opacity, how easily light passes through an atmosphere, are not accurate enough, according to MIT graduate student Prajwal Niraula, a co-author on a new paper published Thursday in Nature Astronomy.

And since Webb studies exoplanets — planets around stars other than our Sun – by measuring the wavelengths of light that pass through a planet’s atmosphere using its spectroscopy instrument, the less accurate models could mean Webb telescope observations are off from reality by an order of magnitude.

“Currently, the model we use to decrypt spectral information is not up to par with the precision and quality of data we have from the James Webb telescope,” Niraula said in a press statement. “We need to up our game and tackle together the opacity problem.”……

If they don’t update their models to match the accuracy of the Webb Telescope’s optics, scientists say, they could miss or misconstrue major discoveries in planetary science
