Remnants of 10 billion years old Earth discovered in white dwarf's atmosphere.

"Artist’s impression of the old white dwarfs WDJ2147-4035 and WDJ1922+0233 surrounded by orbiting planetary debris, which will accrete onto the stars and pollute their atmospheres. WDJ2147-4035 is extremely red and dim, while WDJ1922+0233 is unusually blue.

In space is a binary star system of two white dwarfs WDJ2147-4035 and WDJ1922+0233. The age of WDJ2147-4035 is about 10,7 billion years old and it spent the 10,2 billion years cooling as a white dwarf. WDJ1922+0233 is much younger.

And it's almost sure. That those white dwarfs impacted each other. Then they started to orbit each other. So those white dwarfs have been separated a long time ago.

An interesting thing is that white dwarfs are remnants of the stars, quite similar to the sun. If the red participant of the binary star WDJ2147-4035 was really like our sun, it spent an incredibly short period of its life as the star that has nuclear fusions and its energy production. That means WDJ2147-4035 produced energy for only 0,5 billion years.

"The astronomers used spectroscopic and photometric data from GAIA, the Dark Energy Survey, and the X-Shooter instrument at the European Southern Observatory to calculate how long the stars have been cooling. They found that the ‘red’ star WDJ2147-4035 is around 10.7 billion years old, of which 10.2 billion years have been spent cooling as a white dwarf".

The blue participant of that system WDJ1922+0233 pushes debris to the red participant WDJ2147-4035. And that means the atmosphere of that red dwarf is polluted by planetary debris. The thing that makes this necro-planetary system interesting is that both white dwarfs might have an independent planetary system.

The remnants of the earth-like planet in the red dwarf's atmosphere are causing interesting speculations. Necroplanetology means that science research the remnants of exoplanets near dead stars. The most interesting of the star types are white dwarfs because they were once like the sun.

And if there is some kind of civilization in the universe that is more advanced than humans. Remnants of that civilization could be found near white dwarfs. If that hypothetical civilization wants to stay alive after the star erupts as a nova.

They must create an interstellar flight. But in that case, those civilizations would not return. And that means they must make only space arcs. The generations would change in the spacecraft fleet that speed is about 0,1-50% of the speed of light.

Or create giant space stations that would go to the shadows of those planets. In that case, planets could protect giant O'Neill cylinders where those creatures are moving when they cannot stay on their planets.

When we are thinking about that earth-like planet remnant in that white dwarf system that is 90 light years away from Earth there is the possibility that the origin of that planet is somewhere else than in this binary dwarf-star system.

By the way...

What is the difference between nova and supernova? Nova can mean many types of stellar explosions. But one determination for nova is that is the end of the life of the star that is too small for forming neutron stars. So, if the result of the star's last explosion is a white dwarf. We should talk about nova. But from the Wikipedia page about nova, you can read more about that eruption.

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper? The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown. But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with th

Nanoparticles are excellent tools for medicine transporters.

"Researchers have developed a new therapy for pancreatic cancer involving nanoparticles that stimulate immune responses and improve drug delivery. This innovative method has led to significant tumor reduction in mice and holds potential for treating other cancers. Credit: SciTechDaily.com" (ScitechDaily, New Nanoparticle Cancer Treatment Successfully Shrinks and Eliminates Pancreatic Tumors) Nanoparticles can carry medicines into wanted cells. The idea is that the same system that feeds those cells transports those nanoparticles into cells that need medicine. When a nanoparticle goes, into a cell, it releases the chemicals into the targeted cells. Because nanoparticles don't let medical molecules interact with a body that makes it possible to create new and more powerful cytostatics. Nanoparticles can transport things like ricin molecules into wanted cells. Ricin is one of the most poisonous chemicals. That chemical is useful for next-generation cytostatics, if researche

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology.

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology. Could a hypothetical Planet X tunnel all radiation? The myth of Planet X still lives. Nobody ever saw that planet, and the thing that supports the theory of previously unknown large-size planets in Kuiper's belt are mysterious anomalies in Neptune's trajectory. The thing is that nothing else supports the theory of the existence of the "invisible planet". The size of the planet must be very big. And its gravitational field strong that it can affect Neptune's trajectory. And the search for that mysterious planet is very long work. In some visions, the mysterious gravitational source is mentioned as the small black hole, but nobody understands why that black hole doesn't seem to interact. In some other theories, Planet X is a glimpse of dark matter. And that thing makes it invisible. But there is one weakness. The dark matter object must have some kind of
