750 light-years away from the solar system, TrES-2b is the darkest planet ever found. It is even darker than coal. It has an albedo of 0.0136, which means that it reflects less than 1% of the light that falls on it. It is a gas giant exoplanet that orbits a G-type star. It is 0.03563 AU from its star. The star's intense light heats TrES-2b to a temperature of more than 980 °C. Reasons for TrES-2b's darkness remain unknown and are an active topic of research.

When Einstein died in 1955, pathologist Thomas Harvey performed the autopsy at Princeton Hospital and decided to remove and preserve the brain for scientific study, hoping to uncover the secrets behind Einstein's genius. Despite the unconventional and ethically questionable nature of his actions, Harvey eventually obtained retroactive permission from Einstein's son, Hans Albert, with the promise that the brain would be used strictly for research. Over the following decades, Harvey sent small pieces of the brain to various researchers. Despite numerous studies, however, no definitive conclusions have been reached on the connection between the physical structure of Einstein's brain and his intellect.

Nuclear Plasma

The strongest substance in the universe forms from the leftovers of a dead star. According to simulations, protons and neutrons in a star's shriveled husk can be subject to insane gravitational pressure, which squeezes them into linguini-like tangles of material that would snap — but only if you applied to them 10 billion times the force needed to shatter steel.

Loop quantum gravity (LQG) is a theory of quantum gravity, which aims to merge quantum mechanics and general relativity, incorporating matter of the Standard Model into the framework established for the pure quantum gravity case. It is an attempt to develop a quantum theory of gravity based directly on Einstein's geometric formulation rather than the treatment of gravity as a force. As a theory LQG postulates that the structure of space and time is composed of finite loops woven into an extremely fine fabric or network. These networks of loops are called spin networks. The evolution of a spin network, or spin foam, has a scale above the order of a Planck length, approximately 10⁻³⁵ meters, and smaller scales are meaningless. Consequently, not just matter, but space itself, prefers an atomic structure. @thecaqm

Is there sound in space?

✔️ Sound is a physical phenomenon generated by the oscillating motion of gas/solid/fluid particles. Most commonly, in everyday life, we hear sound through gas, i.e. air. 
 
If one means a spaceship, which is filled with air, then, certainly, we will hear everything perfectly, but in open space there are no air molecules, so you can enjoy the silence. 

Only not for long, since your eardrums in outer space are ruptured due to the difference in pressure inside and outside (you may feel something similar in an airplane)✨

Why can we sometimes see the moon in the daytime?

✨We sometimes see the moon during the day for the same reason we see it at night — it is reflecting light from the sun — After the sun, the moon is by far the brightest celestial object we can see. But the moon isn't always visible during the day. This is due to Earth's atmosphere and the orbital cycle of our natural satellite.

If our planet didn't have an atmosphere, the moon would be visible from Earth all the time. Meanwhile, the phases of the moon mean that when it moves between Earth and the sun — such as during the new moon — the illuminated side faces away from us and the dark side of the moon faces Earth, making it basically invisible to skywatchers on Earth

How many suns can a planet have?

💥Planets with two suns, such as those in Star Wars, are not uncommon, especially on a cosmic scale. Three suns are much rarer, yet there are cases.

The approximate distance at which stars stop interacting is tens of thousands of astronomical units.

Within these limits, even very distant objects are bound together by invisible forces, which are also constantly distorted by the effects of black holes. Nevertheless, an equilibrium point can theoretically be found.

American researchers give the example of our solar system, in which there are many moons, but the 9 satellites of Jupiter have no effect on the Earth. In the same way, the stars, being in the same system, may not have a destructive effect on their planet.

Sun imaged at night

This picture is extraordinary because it shows the Sun imaged at night in neutrino light. Neutrinos are subatomic particles produced in the Sun's core through nuclear reactions. Although photons from the core take about a hundred thousand years to reach the surface and finally escape at the speed of light, neutrinos take less than 3 seconds to escape the Sun. This is because they do not interact with matter. Hundreds of billions of neutrinos pass through our bodies each second.

Neutrinos are difficult to detect because they only interact through gravity and weak forces. However, in a rare occurrence when a neutrino interacts with an electron in water, it can cause the electron to be accelerated to a speed greater than the speed of light in the water, producing a pulse of light - called Cherenkov light/radiation that specialized instruments can detect.

This type of detection is used in neutrino observatories to study neutrinos and their properties. This image was taken by Super-Kamiokande (also known as Super-K or SK), a neutrino observatory in Japan, using the same principle. The Super K detector is placed 1000 meters below the surface because neutrinos can pass through the Earth unimpeded. The placement also prevents interruptions from cosmic rays and other background sources.

It consists of a large cylindrical tank filled with 50,000 tons of pure water, surrounded by thousands of photomultiplier tubes that detect light produced by neutrinos interacting with the water. The image is obtained through Cherenkov radiation detection in the 50,000 tons of water facility with a 503 days exposure. Brighter colors in the image represent the larger flux of neutrinos.
