Found: First Actively Forming Galaxy as Lightweight as Young Milky Way

11 Dec 2024 11:00am Release ID: 2024-116

 

Summary

This galaxy, which is stretched and magnified, glitters with 10 distinct star clusters that formed at different times.

 

Like fireflies “dancing” on a warm summer night, 10 distinct star clusters appear in observations from NASA’s James Webb Space Telescope. They are held in a cocoon of diffuse light emitted by other stars scattered around them. This galaxy, known as Firefly Sparkle, was taking shape around 600 million years after the big bang.

For the first time, astronomers have identified a still-forming galaxy that weighs about the same as our Milky Way if we could “wind back the clock” to weigh our galaxy as it developed. The newly identified galaxy, the Firefly Sparkle, is in the process of assembling and forming stars, and existed about 600 million years after the big bang.

 

The galaxy is stretched and warped due to a natural effect known as gravitational lensing, which allowed researchers to glean far more information about its contents. (In some areas of Webb’s image, the galaxy is magnified over 40 times.)

 

While it took shape, the galaxy gleamed with star clusters in a range of infrared colors, which are scientifically meaningful. They indicate that the stars formed at different periods, not all at once.

 

“I didn’t think it would be possible to resolve a galaxy that existed so early in the universe into so many distinct components, let alone discover a Milky Way-mass galaxy in the process of forming,” said Lamiya Mowla, the lead author and an assistant professor at Wellesley College in Massachusetts.

 

Since the galaxy is stretched into a long line in Webb’s observations, the researchers were able to identify 10 distinct star clusters and study them individually, along with the cocoon of diffuse light from the additional, unresolved stars surrounding them. That’s not always possible...

Firefly Sparkle Galaxy and Companions in Galaxy Cluster MACS J1423 

(NIRCam Image Description)

 

A frame split horizontally down the middle: 

At left is a galaxy cluster and background galaxies, showing thousands of overlapping objects at various distances. The background is black. The galaxies’ colors vary, including white, pink, orange, and blue. Most galaxies appear as ovals or dots. Just above center is a bright white oversized oval, a supergiant elliptical galaxy. Around it are many thin, long orange or pink arcs. These are background galaxies that appear stretched and distorted. To the bottom right is the outline of a small box. 

 

On the right side is a zoomed in view of this area. There are two smaller circular outlines flanking a larger central oval outline, labeled Firefly Sparkle galaxy. Within it is a long line, pointing from bottom left to top right with 10 circular star clusters in pink, purple, and blue. The circled galaxy to the bottom left is labeled Companion 1 and looks like a bright red dot. At top right, the circled galaxy labeled Companion 2 is lighter red and surrounded by a red disk.

NASA's Webb Finds Planet-Forming Disks Lived Longer in Early Universe

16 Dec 2024 10am Release ID: 2024-135

 

NASA’s James Webb Space Telescope just solved a conundrum by proving a controversial finding made with the agency’s Hubble Space Telescope more than 20 years ago. 

 

In 2003, Hubble provided evidence of a massive planet around a very old star, almost as old as the universe. Such stars possess only small amounts of heavier elements that are the building blocks of planets. This implied that some planet formation happened when our universe was very young, and those planets had time to form and grow big inside their primordial disks, even bigger than Jupiter. But how? This was puzzling.

Per the linked summary and article:

 

. . ."The finding affirms the Hubble result, and it is causing scientists to rethink current models of planet formation"

 

. . ."we must rethink how we model planet formation and early evolution in the young universe" . . .

 

Hmmm, ya think?? The incredible amount of discovery made possible by first Hubble and now the Webb telescope staggers the imagination (not to mention the amount of human and artificial intelligence).  But at the same time it reveals the puny amount that man has uncovered and an even punier amount that he understands.   Thanks for the photos and link. I can never get enough of these photos.

 

(Amos 5:8) 8 The One who made the Kiʹmah constellation and the Keʹsil constellation,
The One who turns deep shadow into morning,
The One who makes day as dark as night,
The One who summons the waters of the sea
To pour them out on the surface of the earth
—Jehovah is his name.

I sometimes conclude this scripture might be more literal than metaphorical: 

Ecc 3:11   "...He has even put eternity in their heart; yet mankind will never find out the work that the true God has made from start to finish..."

A Stellar Explosion 650 Million Light-Years Away Captured by Hubble

 

By ESA/Hubble December 30, 2024

 

The Hubble Space Telescope captures the mesmerizing galaxy LEDA 22057, home to a recent supernova explosion, SN 2024PI.

This new image from the Hubble Space Telescope showcases the galaxy LEDA 22057, located approximately 650 million light-years away in the constellation Gemini. Similar to last week’s featured galaxy, LEDA 22057 is the site of a spectacular supernova explosion. The supernova, named SN 2024PI, was first detected in January 2024 by an automated survey. This survey scans the entire northern half of the night sky every two days and has documented over 10,000 supernovae to date...
