Webb’s Photo of This Influential Galaxy Teaches a lot About the Early Universe

 JUL 31, 2023 JEREMY GRAY

 

James Webb Space Telescope NGC 6822

 

The James Webb Space Telescope recently captured a colorful image of the irregular galaxy NGC 6822. Using its Near InfraRed Camera (NIRCam) and Mid-InfraRed Instrument (MIRI), Webb observed different aspects of NGC 6822, including gas-rich regions and specific organic compounds critical for star and planetary formation.

Rare 'Einstein cross' warps light from one of the universe's brightest objects in this stunning image

By Ben Turner published about 5 hours ago

 

Einstein predicted the existence of these crosses back in 1915. Now, they are used to study distant galaxies.

Webb Spotlights Gravitational Arcs in 'El Gordo' Galaxy Cluster

 

August 02, 2023 10:00AM (EDT) Release ID: 2023-119

 

New image reveals galaxy groups, smudges, and dusty distant objects.

 

The Fishhook. The Thin One. These are just two of the striking targets revealed in new detail by NASA’s James Webb Space Telescope. In July 2022 Webb observed El Gordo, a galaxy cluster that existed 6.2 billion years after the big bang. It was selected as the most massive galaxy cluster known at that time in cosmic history.

 

Galaxy clusters are the heavyweights of astronomy. They have the power to bend and magnify light from more distant objects, a phenomenon known as gravitational lensing that was predicted by Albert Einstein more than 100 years ago. Webb’s infrared image of El Gordo displays a variety of unusual, distorted background galaxies. It also has fueled several new scientific discoveries.

Webb Reveals Colors of Earendel, Most Distant Star Ever Detected

 

Release date: Wednesday, August 9, 2023 10:00:00 AM 

 

Observations hint at companion star

 

Detecting extremely distant stars, or those closest in time to the big bang, can provide insights into the first few chapters of the history of our universe. In 2022, the Hubble Space Telescope broke its own record, and spotted the most distant star yet. This star, nicknamed Earendel, emitted its light within the universe’s first billion years.

[An alphabetical list and a reminder of what we don't know!]

 

It's Going to Take More Than Early Dark Energy to Resolve the Hubble Tension

 

September 4, 2023 BY BRIAN KOBERLEIN

Our best understanding of the Universe is rooted in a cosmological model known as LCDM. The CDM stands for Cold Dark Matter, where most of the matter in the universe isn’t stars and planets, but a strange form of matter that is dark and nearly invisible.

You are right, Tyson do not believe in God. He and other scientists are baffled because of these new discoveries and they will not come to terms with Genesis 1:1  In the beginning God created the heavens and the earth.

JWST’s first triple-image supernova could save the Universe.

SEPTEMBER 20, 2023

 

Named "Supernova H0pe," it shows how JWST plus gravitational lensing can be used to solve the greatest puzzle facing astronomy today.

 

KEY TAKEAWAYS

Large clusters of galaxies aren't only interesting because of the stars, gas, dust, and dark matter inside, but also because of how their gravity magnifies the distant Universe. 

A remarkable find with JWST revealed a gravitationally lensed type Ia supernova, the second most-distant ever discovered, that was caught exploding in three independent images. 

The extraordinary gravity of this galaxy cluster is aligned with many rich, star-forming background galaxies, and might be the key to resolving astronomy's greatest modern puzzle: the Hubble tension.

 

Pic: Galaxy cluster PLCK G165.7+67.0 triply lensed supernova

Here, galaxy cluster PLCK G165.7+67.0 is shown, with the features of background, gravitationally lensed galaxies appearing behind it. The big orange arc at left, called "Arc 2," contains the second-most distant type Ia supernova, and it was seen by JWST on repeat in all three images, as annotated here.

The JWST is Forcing Astronomers to Rethink Early Galaxies

 

The JWST has surprised astronomers again. Contrary to our existing understanding, the JWST showed us that the early Universe was full of fully-formed galaxies similar to the ones we see today. The widely-held belief is that the early Universe was too chaotic in its early years, and frequent mergers would’ve disrupted galaxies’ graceful shapes.

 

Galaxy morphologies are important clues to their history. Understanding how their structure and morphology change over time is critical to understanding them. Astronomers only figured out that there were spiral galaxies in the 1840s when the Earl of Rosse built his gigantic telescope called the Leviathan of Parsonstown. He discovered the spiral nature of some galaxies, which he thought were nebulae at the time. Using his massive telescope, he was the first to discover the Whirlpool Galaxy’s (M51) spiral shape...

Hundreds of Free-Floating Planets Found in the Orion Nebula

Posted on October 4, 2023 BY NANCY ATKINSON

 

It appears that rogue planets – free floating worlds that aren’t gravitationally bound to a parent star – might be more common than we thought. New data from the James Webb Space Telescope have revealed 540 (yes, that’s right) planetary-mass objects in the Orion Nebula and Trapezium Cluster.

 

If confirmed, this would be by far the largest sample of rogue planets ever discovered.

 

Last year, astronomers found 70 free floating worlds throughout the Milky Way....

 

“How pairs of young planets can be ejected simultaneously and remain bound, albeit weakly at relatively wide separations, remains quite unclear,” the researchers wrote in their paper.

 

“The Jupiter Mass Binary Objects or JuMBOs are a really big discovery, we believe,” said McCaughrean, a senior adviser for science and exploration at ESA, on Mastodon. In the pre-print, researchers said that these planetary-mass binary objects is “a result that is highly unexpected and which challenges current theories of both star and planet formation...”

 

The exact mechanisms for how planets go “rogue” are unknown, but several theories exist. The theories include that planets are pulled away from one star by gravitational interactions with other passing stars, or that supernovae kick them out, or that they free float into space after their sun dies.

 Top comment over here has an interesting breakdown.

Astronomer here! According to the preprint,, these are all roughly Jupiter mass objects directly images in the Orion Nebula. Further, ~9% of the sample of 540 candidates are in these binary pairs, which is more than you'd expect from "they randomly found each other" type scenarios. Paper says these pairs are "within 390 AU" of each other, which would be ~2.5x further than us to Voyager I right now. So, basically these aren’t thought to be planets kicked out of their original systems or whatever, but ones that formed in pairs on their lonesome.

 

Now, it’s important to recognize that forming planets and stars is a very complicated process, and there are various steps of stellar/ planetary formation that aren’t fully understood. Maybe not shocking, there’s a lot that has to happen, over many many years! My favorite example of this is we still don’t fully understand for example how small rocky clumps coalesce into meter sized clumps. Obviously it happens, else planets and stars wouldn’t exist, but this was an outstanding puzzle already in the 90s and one reason people said planets would be rare. Now we of course know planets are everywhere, but still can’t explain that step of formation!

 

In this case though, we basically don’t understand how something very small (aka Jupiter sized over stellar sized) can form on its own, and why the existing gas (of which there’s no lack in the Orion Nebula) wouldn’t keep collapsing into something bigger. Simulations normally show that you can’t form something less than ~5x the mass of Jupiter on its own, IIRC.

 

I don’t think anyone is beyond shocked that we don’t know all these details in the theory… but it’s quite another to find observational evidence that directly shows we don’t understand it over speculating, and that’s what JWST provides here! So that’s exciting and will give some of my colleagues quite a bit to ponder! :)

NASA’s Webb Captures an Ethereal View of NGC 346

 

Release date: Tuesday, October 10, 2023 10:00:00 AM Eastern Daylight Time

 

Filaments of dust and gas festoon this star-forming region in a new infrared image from MIRI

 

Within a neighboring dwarf galaxy known as the Small Magellanic Cloud (SMC) lies a dramatic region of star birth – NGC 346, shown here. As the brightest and largest star-forming region in the SMC, it has been studied intensely by a variety of telescopes. NASA’s Hubble Space Telescope showed a visible-light view filled with thousands of stars. More recently, NASA’s James Webb Space Telescope offered a near-infrared vista highlighting both cool and warm dust. Now, Webb has turned its mid-infrared gaze to NGC 346, revealing streamers of gas and dust studded with bright patches filled with young protostars.

Galaxies are only 100 years old


It has been a century since the event that led to the discovery that the Milky Way is not the only galaxy in the universe

PABLO G. PÉREZ GONZÁLEZ
OCT 10, 2023 - 00:23 CEST

 

One hundred years ago, on the night between October 5 and 6, 1923, humans became aware of galaxies for the first time. That was when Edwin Hubble took a picture of what he called the Messier 31 nebula, which we now know better as Andromeda. Most astrophysicists don’t like the word photo and prefer to talk about images of the sky, but Hubble actually used a photographic plate. The plate with which he made the famous photograph measured about 10x13 cm², took data for 45 minutes through the 100-inch Hooker telescope at the Mount Wilson Observatory, in what is now a heavily light-polluted part of Los Angeles. We can think of that photographic plate, called H335H — the Hooker plate 335 taken by Hubble — as the birth certificate we humans created for all galaxies, the first record of  their existence....

 

{An interesting review of how little we knew even just 100 years ago. What will the next century bring? )
