Watches Jupiter's Great Red Spot Behave Like a Stress Ball

Wed 9 Oct 2024 2:15:00 PM EDT Release ID 2024-011

Titanic Storm Wiggles Like a Plate of Gelatin

Jupiter's birthmark is an unbelievably huge storm that’s mysteriously crimson red in color. It looks like a bloodshot cycloptic eye staring back at Earth. The anticyclone churns along a southern mid-latitude cloud belt and has survived in Jupiter's turbulent atmosphere for at least 150 years. What’s mind-numbing is that the Great Red Spot (GRS) is big enough to swallow our entire planet, making it the largest storm in the solar system.

First breathtaking images from Euclid telescope's map of the universe

The Euclid space telescope's massive “cosmic atlas” promises to shed light on fundamental questions in physics and cosmology

 

By James Dinneen 15 October 2024

 

A mosaic of images from the European Space Agency’s Euclid space telescope captures more than 14 million galaxies, offering a first glimpse of a “cosmic atlas”. The mapping project could add to our understanding of the role dark matter and dark energy play in the structure of the universe.

 

“The scale is utterly incomprehensible,” Carole Mundell, the director of science at the ESA, said during the International Astronautical Congress meeting in Italy. Representing the image at full resolution would require more than 16,000 4K TV screens, she said.

 

The mosaic of 260 images is the first glimpse into Euclid’s project to create the largest and most accurate map of the universe yet. The vast number of galaxies was captured during a two-week survey in April and represents only 1 per cent of the final map. The image covers an area of the southern sky about 500 times the size of the full moon.

 

The wispy blue band across the image is dust and gas in the nearby Milky Way, known as “galactic cirrus”, said Mundell. Zooming in reveals swirling galaxies interacting hundreds of millions of light years away, some with a supermassive black hole at their centre that can produce gravitational waves measurable on Earth.

 

Over the next six years, the telescope will autonomously scan about a third of the night sky. The researchers anticipate the final map will show around 8 billion galaxies, each with billions of stars, stretching across 10 billion years of cosmic history.

What does everyone think of this article?

I think humans know very little when it comes the depth of God's knowledge. Some even reject the evidence of his creative power.
So when an article like this comes along, I take comfort, that God has it all under control.
Our depth of knowledge of the workings of the Universe, probably equates to the space we occupy therein. 
I'm still fascinated by the minds who come up with these ideas!  
I mainly look at the pretty pictures....

NASA's Hubble Sees a Stellar Volcano

October 16, 2024 10AM  Release ID: 2024-021

 

Summary
Oddball Stellar Duo Creates Spectacular Fireworks

Located approximately 700 light-years away, R Aquarii is one of the closest stars known to undergo violent eruptions that spew out huge quantities of processed nuclear material into the surrounding space. R Aquarii belongs to the symbiotic class of 150 known variable stars. The symbiotic classification borrows its name from the biological word "symbiosis," whereby two different types of organisms co-exist. In astronomy a symbiotic system is composed of two very different types of stars: a cool red giant star and a small white dwarf companion (a hot burned-out star). They are embedded inside a glowing nebula produced by gas escaping the red giant.

In 1939, Edwin Hubble first detected the expansion of the nebula. In the 1970s astronomers found jets of matter streaming in opposite directions – like a lawn sprinkler. Astronomers now know R Aquarii has actually undergone a series of violent eruptions – the latest one probably occurring in the late 1970's. This happens when the dwarf star swings close to the red giant primary star, siphons off hydrogen, and then the dwarf star's surface undergoes a spontaneous thermonuclear explosion. The Hubble Space Telescope has been keeping an eye on R Aquarii since 1990. The latest images reveal colorful twisted filaments extending very far from the stellar odd couple, resembling the tracings on a child’s Spirograph toy.

James Webb telescope spots the ultimate 'super star cluster' deep in the Milky Way

Jamie Carter published 16 hours ago

Once blocked from view, the most massive young star cluster in the Milky Way has finally been revealed by the James Webb Space Telescope.

A dense cluster of bright stars, each with six large and two small diffraction spikes, due to the telescope’s optics. They have a variety of sizes depending on their brightness and distance from us in the cluster, and different colors reflecting different types of star. 
Patches of billowing red gas can be seen in and around the cluster, lit up by the stars. Small stars in the cluster blend into a background of distant stars and galaxies on black.

JWST's view of Westerlund 1, one of the closest "super star" clusters to the solar system. (Image credit: ESA/Webb, NASA & CSA, M.Zamani (ESA/Webb), M. G. Guarcello (INAF-OAPA) and the EWOCS team)
What it is: super star cluster Westerlund 1

Where it is:
12,000 light-years away in the constellation Ara.

Why it's so special:
Westerlund 1 is a galactic factory of epic proportions. Visible from Earth's Southern Hemisphere just below the tail of the Scorpion — and close to the core of the Milky Way — it's the largest known star cluster in our galaxy.

It's the ultimate example of a "super star cluster." While most such clusters are about 10,000 times the sun's mass, Westerlund 1 is 50,000 to 100,000 times the solar mass. Some of its hundreds of very massive stars are 2,000 times larger than our sun. If they were in the solar system, they would reach as far as the orbit of Saturn and shine 1 million times brighter than the sun. If Earth orbited a star within Westerlund 1, our night sky would be full of hundreds of stars as bright as the full moon.

Astronomers think that within the next 40 million years — the blink of an eye in cosmic terms — more than 1,500 supernovae (stars exploding at the end of their lives) will light up Westerlund 1. Right now, the cluster is about 3.5 million to 5 million years old.

How has the James Webb Space Telescope changed cosmology?

 

More than two years after JWST began science operations, our Universe now looks very different. Here are its biggest science contributions.

 

Key Takeaways

Prior to JWST, our best observations plus our leading theories had combined to create a “consensus” picture of the Universe, showing us the broad strokes of how our cosmos grew up and gave rise to us.

 Since July of 2022, however, when JWST’s science operations began, we’ve learned an incredible amount of new information about the Universe, from star and planet formation to the earliest galaxies.

 This hasn’t led to a revolution in terms of how we conceive of the Universe, as some had hoped, but it has led to a number of important revisions in our consensus picture. Here’s what has and hasn’t changed.

 

It’s hard to fathom, but it’s barely been two years since the James Webb Space Telescope (JWST) began its science operations in July of 2022. Back then, we had an incredible amount of information about our Universe that we had already uncovered, as well as a great number of cosmic puzzles we were still facing with no obvious solution in sight. We knew that our Universe was:

 

13.8 billion years old,

began with a hot Big Bang in the aftermath of an inflationary period,

was dominated by the mysterious dark energy and dark matter, whose nature was unknown,

with the big problem of the “Hubble tension” looming over our measurement of the expansion rate,

where supermassive black holes were spotted to be very massive even early on,

and where even the earliest galaxies detected were massive, somewhat evolved, and bright.

Our picture of the Universe included galactic, stellar, and chemical evolution, from a pristine early state to the late-time state that mirrors what we observe nearby. It included a history where more than two sextillion stars, locked up in trillions upon trillions of galaxies, were spread all throughout an observable Universe that spans 92 billion light-years in diameter. But many big questions remain...

'Blood-Soaked' Eyes: NASA's Webb, Hubble Examine Galaxy Pair

 

October 31, 2024 Release ID: 2024-13

 

Summary

By teaming up, these two space telescopes have delivered the highest resolution image of IC 2163 and NGC 2207 to date in a combination of mid-infrared, visible, and ultraviolet light.

 

This ghastly galactic “countenance” recalls mythological human-hunters like the Algonquian wendigo — an emaciated figure with ashen flesh and glowing eyes that grows larger and larger as it feasts, and is never satiated.

 

But this image, captured by the James Webb and Hubble space telescopes, isn’t a case of galactic cannibalism — at least, not yet.

NASA's Hubble, Webb Probe Surprisingly Smooth Disk Around Vega

 

November 01, 2024 Release ID: 2024-030

 

Summary

Legendary Star Lacks Evidence for Large Planet Construction

 

Ever since the dawn of human consciousness, skywatchers have been mystified by "wandering stars." These are the five visible planets circling our Sun. It was thought they influenced earthly affairs and allowed for future predictions through the pseudoscience of astrology. But real astronomers asked: where did the planets come from?

 

In the late 18th century, Immanuel Kant and Pierre-Simon Laplace hypothesized that the planets condensed out of a disk of dust and gas encircling the newborn Sun. This was based on the observations that the planet's orbits are co-planar, and they all move in the same direction, like a spinning phonograph record. In essence, their orbits are the residual skeleton of the long-vanished disk. But astronomers had to wait 200 years before the first telescopic evidence was collected that supported Kant and Laplace's conjecture. With the Infrared Astronomical Satellite (IRAS), they found a puzzling excess of infrared light from warm dust around the bright blue star Vega in the summer constellation Lyra. This was interpreted as a disk of planet-forming material. Observations with IRAS discovered that such disks are common around young stars. Vega was the first clue.

How do scientists color the Universe?

November 15, 2024

When we see pictures from Hubble or JWST, they show the Universe in a series of brilliant colors. But what do those colors really tell us?

Key Takeaways

➡️ When we look at astronomical images of the Universe, whether from Hubble, JWST, or any other observatory, they typically show a broad array of colorful features. 

➡️ But these color-coded images don’t necessarily show us the same things human eyes would see; instead, they’re optimized to encode important information in an easy-to-process visual format.

 

Here’s how scientists “colorize” the Universe in a variety of ways, and what those colorizations tell us about what’s truly present and detectable inside these objects...Read more:
