Why do all planets look different?

The reason why the planets seem different to us is that each of them is made up of different substances. Despite the fact that they all revolve around the Sun and are part of the same solar system, their composition varies. Very little is known about what the planets are made of, and this is one of the questions that man hopes to answer with the help of space studies that have been carried out and are planned in the future.

Let's take a look at each of the planets and see what we know about their composition.

Mercury is a small mountain world. It has several dark areas and many craters, but there is no atmosphere or water in the notes. Venus is a white orb with hazy spots. It is almost completely covered with a layer of white clouds, which do not consist of water vapor, but of hydrochloric acid vapor. Beneath these clouds is the atmosphere of Venus, mostly composed of carbon dioxide, which is unbreathable. It absorbs solar heat like a blanket, so the temperature on the planet's surface reaches about 500 ° C, and because of this, there is no liquid water on Venus. Mars is called the red planet because of the color of its deserts. It is half the size of Earth and has a very thin layer of carbon dioxide atmosphere in which clouds form. No definite signs of life have been found on Mars. Maybe it's because it's very cold there.

Jupiter appears before us as a yellowish ball with colored bands of clouds swirling around it, and a giant red spot clearly visible against the clouds. Jupiter is a giant liquid ball of mostly hydrogen and helium that gets denser towards the center of the planet. Saturn is mostly liquid hydrogen and has several bright rings around it. They are made up of countless particles that move in their orbits around the planet like small moons.

There are also rings around Uranus, but they are much darker than the rings of Saturn. Neptune is a dim greenish planet, while Pluto is the smallest planet in the solar system. It has an elliptical orbit and therefore sometimes comes closer to the Sun than Neptune. Space exploration through satellites and robotic stations is helping scientists learn more about every element of our solar system.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Memory eraser 18.11.2021

Scientists have developed a "memory eraser" similar to the one shown in the movie "Men in Black". Researchers at Kyoto University have done a successful memory-deletion experiment on mice.

The rodents learned a new task, then were subjected to an optical effect with a special device, and as a result, they completely lost their memories of what had happened to them before. The technology is based on the destruction of the cofilin protein, which is responsible for the transition of short-term memory to long-term memory.

Is it possible to erase a person's memory in the same way? In fact, it’s not quite the same as in this film, when they just shine in the eyes with some kind of device.

First, these animals are genetically modified. They produce a modified protein that, when exposed to light, generates molecules that lead to local destruction. And secondly, they also have a second modified protein that helps to perceive this light. Plus, they also need to implant this light source. That is, these mice are not just genetically modified, but in their head, right in the skull, a window is made and an optical fiber is inserted there, which transmits light of a certain frequency, which shines on those nerve cells that work there.

Of course, this is not good for humans. Because, first, we need to insert this fiber that will shine into the brain. And if you shine like that on an ordinary person, not modified, then nothing will happen. We do not yet know exactly how memory works - we know the pieces of this process. We know the specific nodes through which the signal passes. And there, when they intervened in mice, they acted on just one of the nodal parts of the system. And we have this nodal part in the depths of the brain, where in order to crawl through, you need to go through ten centimeters of brain tissue.
