Mercury: A Planet of Extremes
✨Mercury, the innermost planet in our solar system, orbits within the outer reaches of the Sun's atmosphere. This proximity subjects it to scorching temperatures, with one side perpetually baked while the other remains perpetually frozen. Its surface is a testament to its tumultuous history, scarred by countless impacts from asteroids, comets, and other space debris.
✨Indeed, Mercury boasts a denser concentration of craters than even our own Moon. Lacking a substantial atmosphere, the planet experiences extreme temperature fluctuations. Daytime temperatures can soar to a blistering 450 degrees Fahrenheit in most regions, surpassing 840 degrees near the equator.
✨Conversely, nighttime temperatures plummet to frigid lows of -275 degrees Fahrenheit. Like our Moon, Mercury exhibits synchronous rotation, meaning the same hemisphere always faces the Sun.
✨Historically, Mercury was mistaken for two distinct stars. The Greeks, for instance, referred to the morning "star" as Apollo and the evening apparition as Hermes. It was only in the fifth century that they recognized these celestial bodies as a single entity.
✨In 1991, a groundbreaking discovery emerged when radar signals were successfully bounced off Mercury's poles. The data strongly suggested the presence of ice sheets at both poles. This phenomenon can be attributed to the unique geometry of the polar regions, where the Sun remains perpetually near the horizon, maintaining perpetually frigid temperatures.
✨Mercury's rotation exhibits an intriguing peculiarity, resulting in an exceptionally long day. Its slow rotational speed dictates that a Mercurian day is twice as long as it's a year. Despite its rapid orbital velocity – a remarkable 30 miles per second, making it the fastest orbiting planet in our solar system
– Mercury completes its orbit around the Sun in a mere 88 Earth days. However, a full rotation on Mercury takes a substantial 176 Earth days.
✨Mercury follows an elliptical orbit around the Sun, maintaining an average distance of approximately 36 million miles. Although it completes a full rotation every 59 Earth days, Mercury ranks second slowest in rotational speed, trailing only Venus.

Part-2
✨Mercury is Moon like in appearance
and has no life. It has no water except for polar ice sheets. It does have a very thin atmosphere. It is made up of helium,hydrogen, oxygen and sodium.
✨The sun’s rays are 7 times more
powerful on Mercury than they are here on earth. It reflects only 6% of the sunlight shone on it. The sun would appear 2 ½ times larger in the sky, than it does here. It has no moons. It’s a small and rocky planet.
✨Mercury’s diameter is 3,032 miles at the equator, which makes it 2/5 the size of earth. The gravity is about 1/3 of ours.
✨Mercury is covered by a thin layer of
silicates, has many deep craters that look like what we have on our Moon. The largest crater is 800 miles across. There are some indirect signs of volcanism, but there are no cones or volcanic mountains.
✨Its core may be liquid iron that it makes up as much at ¾ of its radius.
It is the closest planet to the Sun. It is difficult to send probes there.
✨Because of the increased dangers of being so close to the Sun. Its distance from us and the unlikely ability of it providing informational benefits that could come from its exploration, no human exploration has been planned.

😃 Did you know what are forcefields?
⚛In speculative fiction, a force field, sometimes known as an energy shield, force shield, force bubble, defence shield or deflector shield, is a barrier made of things like energy, negative energy, dark energy, electromagnetic fields, Gravitational fields, electric fields, quantumfields, plasma, particles, radiation, solid light, or pure force.
⚛ It protects a person, area, or object from attacks or intrusions or even deflects energy attacks back at the attacker. This fictional technology is created as a field of energy without mass that acts as a wall, so that objects affected by the particular force relating to the field are unable to pass through the field and reach the other side, are deflected or destroyed.
⚛ This concept has become a staple of many science-fiction works, so much that authors frequently do not even bother to explain or justify them to their readers, treating them almost as established fact and attributing whatever capabilities the plot requires.
⚛The ability to create forcefields has become frequent superpower in superhero media.

🔥In this extraordinary universe how many of us have eagerness to learn starting elementary to the vast and complex world of life ?🤔I left the answer for who gonna read the below article .
What is brain 🧠?
The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS.
What is the brain made of?
Weighing about 3 pounds in the average adult, the brain is about 60% fat. The remaining 40% is a combination of water, protein, carbohydrates and salts. The brain itself is a not a muscle. It contains blood vessels and nerves, including neurons and glial cells.

🧠What is the gray matter and white matter?
👉Gray and white matter are two different regions of the central nervous system. In the brain, gray matter refers to the darker, outer portion, while white matter describes the lighter, inner section underneath. In the spinal cord, this order is reversed: The white matter is on the outside, and the gray matter sits within.
👉Gray matter is primarily composed of neuron somas (the round central cell bodies), and white matter is mostly made of axons (the long stems that connects neurons together) wrapped in myelin (a protective coating). The different composition of neuron parts is why the two appear as separate shades on certain scans.
👉Each region serves a different role. Gray matter is primarily responsible for processing and interpreting information, while white matter transmits that information to other parts of the nervous system.

⚛ Matter and Antimatter Destroy Each Other
–One of the coolest things about high energy physics, also called particle physics, is the discovery of antimatter.
–Antimatter is sort of the reverse of matter. The counterparts of electrons are called positrons (which are positively charged), and the counterparts of protons are antiprotons (which are negatively charged).Even neutrons have an antiparticle: anti neutrons.
– A neutron is made up of smaller particles called quarks, which have antiparticle versions, too.So the antineutron has no charge just like the neutron, but each of the quarks it’s made of is the anti- version of the neutron quarks.
–In physics terms, matter is sort of on the plus side, and antimatter sort of on the negative side. When the two come together, they destroy each other, leaving pure energy — light waves of great energy, called gamma waves. And like any other radiant energy, gamma waves can be considered heat energy, so if you have a pound of matter and a pound of antimatter coming together, you’ll have quite a bang.
–That bang, pound for pound, is much stronger than a standard atomic bomb, where only 0.7 percent of the fissile material is turned into energy. When matter hits antimatter, 100 percent is turned into energy.

Solar-Maximum
The magnetic pole of the Sun switch places every eleven years in a cycle called Solar max or solar maximum. At the height of this cycle or solar maximum, the Sun's magnetic poles flip. Along the way, changes in the Sun's magnetism produce a greater number of sunspots, more energy and cause solar eruptions of particles

😃what is parallel universe ?
👉Parallel universe, also known as a parallel dimension, alternate universe, or alternate reality, is a hypothetical self-contained plane of existence, co-existing with one's own. The sum of all potential parallel universes that constitute reality is often called a "multiverse".
👉While the three terms are generally synonymous and can be used interchangeably in most cases, there is sometimes an additional connotation implied with the term "alternate universe/reality" that implies that the reality is a variant of our own, with some overlap with the similarly-named alternate history.
👉 The term "parallel universe" is more general, without implying a relationship, or lack of relationship, with our own universe. A universe where the very laws of nature are different – for example, one in which there are no Laws of Motion – would in general count as a parallel universe but not an alternative reality and a concept between both fantasy world and Earth.

Mars and Water
👉In the distant past, Mars had floods, and it looks like it rained there. There are multitudes of evidence suggesting erosion from moving water. Ice patches near the poles have been found that are as big as seas. Ancient coastlines have been discovered. A snow flake was photographed on Mars!
🤔 What happened to the liquid water?
👉 The loss of liquid water could possibly be attributed to Mars losing its magnetic field of protection, allowing the harmful rays of the Sun to eradicate most of atmosphere.
👉By losing most of its atmospheric air pressure, Mars could no longer sustain water in a liquid form. As the planet chilled, due to for loss of its tempering atmosphere, Mars became too cold and dry to support liquid water. The water simply froze or evaporated.
👉Although there is much water ice on
the planet, no liquid water has been found on its surface. There still may be some under the surface due to remaining warm pockets in Mars’ crust.
👉In summary, water needs the right
amount of pressure and heat to remain in a liquid state. The surface of Mars presentlycannot support liquid water.

Planet Venus/Zhura
✨Known as the “planet of love and
mystery”, it is the second planet from the Sun. Shrouded in a thick cover of clouds. Venus is one of the five originally known planets.
✨In the days of the ancient Greeks,
Venus was called #Phosphorus. The
Babylonians, Egyptians and Chinese thought they were seeing two stars. Pythagoras proved it was a planet, which means “wanderer amongst the fixed stars” in Greek.
✨ The Mayans used Venus as a point
of calculation to construct their accurate calendar. The Romans associated the planet with love, and their goddess of love is named Venus.
✨Venus is the third brightest object in
our sky: (First the Sun, then the Moon and then Venus).
Did you know?
A key to discovering the distance from the Sun to the Earth was the measuring of distances between Venus and our star. This was done by Mikhail Lomonosov of Russia in the 1700s.
✨One rotation of Venus is equal to 243.1 Earth days, making it a very slow-turning planet. It has a 225 earth day year. So, for Venus the day is longer than the year!
✨Venus is a virtual twin of Earth in
size. It is 7,519 miles wide at the equator.
Shrouded in a thick set of clouds partly composed of toxic sulfuric acid, it has
a day- time temperature of nearly 900
degrees. The atmosphere is nearly ninety times the thickness of the air around Earth.
✨This means that the pressures are great, and moving through its atmosphere would resemble walking in water slowly. Storms full of lightning and sulfuric acid rain give the planet a hellish quality.
✨Venus is suspected of having many active volcanoes. Probes have taken a set of radar images that reach below the clouds to give us a feel for the landscape.
✨In many ways the geography resembles Earth, with one major exception; it has no water. This second planet is about 66,000,000 miles from the Sun.
✨ Venus had virtually the same size and chemical composition as our planet did. So, why did these two planets end up so different?
✨Venus is 25,000,000 miles closer to the Sun, putting Venus within its’ outer atmosphere, exposing it to a large volume of solar winds.It is a cloudy, burning, acidic, pressured hell, with molten sulfur lakes dotting the surface and acid steam clouds rising up, creating sulfuric acid droplets that rain down on the landscape.
✨Venus has carbon dioxide as the dominant gas in its atmosphere. It also has a unique feature that occurs nightly to its atmosphere.The sky glows. This is caused by the reconnecting of
oxygen atoms into molecules during night time.
✨There is atomic oxygen, hydrogen and helium in the higher clouds of Venus, but there is no measurable nitrogen in its air.
✨These chemical clues suggest that there were ancient seas of deuterium, a heavy isotope of hydrogen. Artist conception of weather underneath the
clouds.
✨Even though there are thick sets of
clouds and a thick atmosphere, some
sunlight does reach the surface, so much so that pictures can be taken without lighting aids.
✨This is because the Sun is closer and
therefore so bright it can penetrate these dense layers of clouds.
✨A certain rock type has been
discovered on the surface. Granite! This is another parallel with Earth. Venus is what Earth could have been. (You can see that the Sun has a very powerful influence on its planets.)
