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

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.

Could this be the thing, that some people don't want you to know about zombies?

Could this be the thing, that some people don't want you to know about zombies? The simplest way to control zombies, which are made by using tetrodotoxin, which is called "zombie poison" is to use the automatic dispenser, which is normally used in diabetes treatment. In this case, the dispenser would be loaded by using tetrodotoxin. If the level of this poison is right, the person would be totally under the control of other people. And if the system cannot detect this poison there is a possibility to make the laboratory experiment when the staff will follow the decrease of the tetrodotoxin, and then the system can use a simple clock, which will inject poison to the body of a victim after a certain time. This would be an effective tool in the hands of military and counter-terror operators. Those zombies can be captured enemy operators, who will send back, and then they just kill their ex-partners. By using genetically engineered bacteria could be possible to create t...

The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like.

.     The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like. Above is the image of the nano-submarine. There is introduced an idea, that this kind of system would equip with living neurons, which makes it like some kind of artificial bug or mosquito. The idea is that the robot can take the nutrient by using the robot tube, which acts like a proboscis. The neurons can get nutrients and the rest of the machine can use small fuel cells or the energy to that system can deliver by using the radio waves. Futurologists are thinking about the ideas, what the hybridization of the neurons and machine would look like? Could the hyper-technical civilization look like the group of midget submarines? Those submarines might take nutrients for the neurons, what is living in them. The purpose of the midget submarines, which might be size less than a couple of millimeters would maximize the survivability of the neurons. One of the most intere...

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...
