Is the Sun made from liquid metal hydrogen ?
This theory by Pierre-Marie Robitaille, try to solve some problem with Sun physic and Fusion Theories.
Under pressure of Sun Mass, the Hydrogen & Helium is so compress, it turn in liquid metal form.
According Robitaille in this state Hydrogen fusion easier, as under Plasma in current theories.

However Robitaille theory base on pile of assumptions, if one is false, rest is faulty.

200 years ago, scientific calculations about the life of the sun were made by assuming that the star was made up of burning carbon. What will they imagine in another two hundred years?... These guys always get these things wrong.:rolleyes:
 
Scientists are refining plans to build the world’s biggest machine at a site beneath the Swiss-French border. More than $30bn (£23bn) would be spent drilling a 91km circular tunnel in which subatomic particles would be accelerated to near light speeds and smashed into each other. From the resulting nuclear debris, scientists hope they will then find clues that would help them understand the detailed makeup of the universe.

It is an extraordinarily ambitious project. However, it is also a controversial one – for many scientists fear the machine, the Future Circular Collider (FCC), could soak up funding for subatomic physics for decades and leave promising new research avenues starved of resources.

Others argue that the mega-collider is being imposed on physicists by senior officials at Cern, the European Organization for Nuclear Research, without properly consulting researchers.

…

However, the technology to accelerate protons at the unsurpassed energies proposed for the FCC does not exist yet. It is merely assumed that, in 40 years’ time, it will have been developed. Such an assumption worries some scientists, as well as the fact that the FCC will cost so much that it will lock scientists into a device that would monopolise funds for particle physics for decades.

Despite the stupendous pressures resulting from gravitational confinement I'd say that the Sun's interior is far too hot for liquid metallic hydrogen to be present, IIRC the hydrogen/helium plasma in the core of the Sun is ~six times denser than gold.

That’s the proper attitude in terms of looking at space expenses.

I remember reading old Pop Mech stories about how taxpayers were proud of great sums of money going to do science in remote locations—-an attitude the Greatest Generation had in spades that today’s tech-bros lack.
 
ALMA Discovers “Space Tornadoes” Around the Milky Way’s Core

Swirling through the Milky Way’s central zone, surrounding the supermassive black hole Sgr A*, dust and gases constantly churn as energetic shock waves ripple. An international scientific team using the Atacama Large Millimeter/submillimeter Array (ALMA) has sharpened our view of this action by a factor of 100, discovering a surprising new filamentary structure in this mysterious region of space.

Here are a couple of new ones, one is from Dr. Becky and it turns the results of her recently published paper to do with the appearance of Smoot-disc galaxies and the second is from Anton Petrov concerning recent findings about the Andromeda galaxy:


The James Webb Space Telescope, JWST, has been surprising us with new results about the early Universe that we can’t yet explain for the past few years now; from the little red dot galaxies, to the over massive galaxies, and finding galaxies with features like spiral arms earlier in the Universe than we ever thought they should exist. And this month was no exception, when a paper was published by Smethurst and collaborators on the Galaxy Zoo and CEERS teams claiming to have found featureless disc shaped galaxies way earlier in the Universe’s history than we ever thought possible. That’s right, we’re talking about my own research in this week’s video, and I’m so excited that it’s finally been published so that we can chat all about it...

PBS Space Time has uploaded a video pointing out that Earth had at least once in its' past an ring-system orbiting it:


Planet Earth is the jewel of the solar system—the shimmery blue oceans, the verdant green forests, the wispy whimsical cloud formations. Saturn is the only competitor for most gorgeous planet with that giant ring system. Hmm… what if we could put the jewel of the Earth in its own ring? Then no contest. Well, there’s an extremely good chance that Earth once DID have a ring system. At least, that’s the proposal by a recent study that has evidence that a mysterious burst in meteor activity nearly half a billion years ago was actually caused by that ancient ring system collapsing onto the Earth. And, you know, if we had a ring once maybe we can have one again.

Here's a PBS Space Time video on what distant from Earth would a supernova trigger a mass-extinction event:


The deaths of massive stars results in one of the most beautiful and violent events in the universe: the supernova. They are so luminous we can see them here on Earth and historical records show that we can even see them into the day. But supernovas release deadly and violent radiation that could destroy our atmosphere. So how far away do these supernova have to be for humanity to be safe? And when will the next supernova occur

So the most accurate map of the Milky Way galaxy has been released:


Astronomers have released the most accurate map of the Milky Way to date, built from an astonishing three trillion observations of two billion celestial objects over 11 years. It’s the masterpiece of the European Space Agency’s Gaia mission. For the past decade, Gaia has been tirelessly scanning the sky, and the results are breathtaking—offering both face-on and edge-on views of our galaxy in stunning detail. But Gaia did more than just map the stars—it uncovered secrets about the Milky Way that we never knew existed.

Warwick astronomers discover doomed pair of spiralling stars on our cosmic doorstep

Significantly, James’s new system is the heaviest of its type ever confirmed, with a combined mass of 1.56 times that of the Sun. At this high of a mass, this means that, no matter what, the stars are destined to explode.

The explosion is not due for another 23 billion years, however, and despite being so close to our solar system, this supernova will not endanger our planet.

Right now, the white dwarfs are leisurely spiralling around each other in an orbit taking longer than 14 hours. Over billions of years, gravitational wave radiation will cause the two stars to inspiral until, at the precipice of the supernova event, they will be moving so fast that they complete an orbit in a mere 30 – 40 seconds.
Click to expand...

…

For the supernova event, mass will transfer from one dwarf to the other, resulting in in a rare and complex supernova explosion through a quadruple detonation. The surface of the mass-gaining dwarf detonates where it is accumulating material first, causing its core to explode second. This ejects material in all directions, colliding with the other white dwarf, causing the process to repeat for a third and fourth detonation.

The explosions will completely destroy the entire system, with energy levels a thousand trillion trillion times that of the most powerful nuclear bomb.

Nearby exoplanet could offer clues about atmospheres around hot, rocky alien worlds

The exoplanet, L 98-59 c, is a hot, rocky world slightly larger than Earth that orbits a bright, young star about 35 light-years away from us. While the planet itself was discovered back in 2019, a new analysis of Hubble Space Telescope observations suggests it may be capable of hosting an atmosphere, adding to the diversity of known terrestrial worlds with clearly defined "air."

If confirmed, the new findings would also make L 98-59 c the first planet of its size with a detected atmosphere, astronomers say, potentially setting new constraints on the atmospheres of worlds with this size and their ability to endure extreme environments created by the harsh conditions of young, flaring stars.

Dr. Becky has put out a video concerning naked singularities and the cosmic censorship problem:


Nothing can escape a black hole; what’s going on inside that point of no return past the event horizon is completely unknown to us. Is all the matter crushed down into an infinitely dense, infinitely small point known as a singularity? Or is something else going on? Annoyingly, under the laws of physics as we understand them, cosmic censorship says will never know what happens beyond the event horizon. Or will we? Because when we run the maths, using Einstein’s equations of general relativity, and sprinkling in a little quantum mechanics, out pops the idea of naked singularities - infinitely dense regions of space, without an event horizon shielding them from view. Singularities that we might be able to see, and observe, to work out what does happen when matter collapses down to infinite density. Now this is all still hypothetical, we’ve never found a naked singularity out there in the universe yet, although some objects have come tantalisingly close to looking like one…​

Lingering brightness provides evidence for how planet met its demise.
Every year, scientists around the world apply for observing time on NASA’s James Webb Space Telescope. When proposals are selected after a vigorous vetting, the programs go into Webb’s observation queue for the future, ready to be scheduled based on various factors, including windows of visibility.
However, what if an astronomer wants to study something, but they don’t know ahead of time exactly when that event will take place? Or where? Think supernova explosions or a gamma ray burst. This is called a Target of Opportunity (ToO) observation, which astronomers can define in the proposal planning phase, ready to have them ‘enacted’ when the time comes.
One of the first ToO programs performed by Webb has now proven fruitful, providing insights into the immediate aftermath of when a star swallowed its own planet.

And from V101 concerning the fate of the Galileo atmospheric probe:


In 1995, a probe embarked on a journey not many people know about today: To fall into the gas giant Jupiter.
The mission was to plunge into Jupiter and find out what is happening below its chaotic clouds. Called the Galileo Atmospheric probe, it was engineered to withstand crushing pressures, scorching temperatures and hypersonic speeds. An environment that can only be described as extreme. Its mission was brief, but revolutionary. In just over an hour, it revealed a side of Jupiter no one had ever seen and no one has seen since. Yet, what became of this robotic explorer? What happened after we lost contact? Want to help me make videos?
